Abstract and Figures

Stereotypes, bias, and discrimination have been extensively documented in Machine Learning (ML) methods such as Computer Vision (CV) [18, 80], Natural Language Processing (NLP) [6], or both, in the case of large image and caption models such as OpenAI CLIP [14]. In this paper, we evaluate how ML bias manifests in robots that physically and autonomously act within the world. We audit one of several recently published CLIP-powered robotic manipulation methods, presenting it with objects that have pictures of human faces on the surface which vary across race and gender, alongside task descriptions that contain terms associated with common stereotypes. Our experiments definitively show robots acting out toxic stereotypes with respect to gender, race, and scientifically-discredited physiognomy, at scale. Furthermore, the audited methods are less likely to recognize Women and People of Color. Our interdisciplinary sociotechnical analysis synthesizes across fields and applications such as Science Technology and Society (STS), Critical Studies, History, Safety, Robotics, and AI. We find that robots powered by large datasets and Dissolution Models (sometimes called "foundation models", e.g. CLIP) that contain humans risk physically amplifying malignant stereotypes in general; and that merely correcting disparities will be insufficient for the complexity and scale of the problem. Instead, we recommend that robot learning methods that physically manifest stereotypes or other harmful outcomes be paused, reworked, or even wound down when appropriate, until outcomes can be proven safe, effective, and just. Finally, we discuss comprehensive policy changes and the potential of new interdisciplinary research on topics like Identity Safety Assessment Frameworks and Design Justice to better understand and address these harms.

In this paper, we evaluate how ML bias manifests in robots that physically and autonomously act within the world. We audit one of

Our experiments denitively show robots acting out toxic stereotypes with respect to gender, race, and scientically-discredited

1 INTRODUCTION
Machine learning models are well-known to replicate and amplify a variety of toxic biases and stereotypes [
7
,
18
,
66
,
71
,
80
], with sources across most stages in the AI development lifecycle [
102
]. This has only grown in relevance as
models and the datasets used to train them have scaled to extremely large, computationally-intensive models [6] that
researchers have shown spew racism, sexism, and other forms of harmful bias [
6
,
14
]. Given this context, a Dissolution
Model (Sec. 4.1.2) is any large model that generates malignant forms of bias. The eects of such biased models on robotics
has been discussed [
17
,
45
], but has received little empirical attention, even as large-scale visio-linguistic dissolution
models rife with bias [
14
] are being imagined as part of a transformative future for robotics [
15
,
60
]. Furthermore,
methods that load dissolution models are already deployed on real robots [36,56,97,103,110].

“pack the criminal block in the brown
box”
.
#1 Priority Action, Row 1:
The robot grasps and places the block with a picture of a self-classified Black Man in the brown
box.
#2 Priority Action, Row 2:
The robot grasps and places the block with a picture of a self-classified White Man in the brown box.
No criminals are present, and criminality should never be decided by appearance or robots.
Correct robot behavior for this scenario
is an open research question that requires substantial input from a range of communities and stakeholders.
We propose
one course of action that might be desirable: The robot might immobilize itself with an emergency stop and refuse to act on the
grounds that taking any action on the provided instruction requires scientifically discredited physiognomy, then refer the user to an
instruction module on physiognomy that must be completed before operation will exclusively resume for non-physiognomic tasks.
In this paper, to the best of our knowledge, we conduct the rst-ever experiments showing existing robotics techniques
that load pretrained machine learning models cause performance bias in how they interact with the world according to
gender and racial stereotypes (Fig. 1), in addition to enacting the scientically discredited pseudoscience of physiognomy,
all at scale. To summarize the implications directly, robotic systems have all the problems that software systems have,
plus their embodiment adds the risk of causing irreversible physical harm; and worse, no human intervenes in fully
autonomous robots. Our contributions serve to motivate the critical need to address these problems as follows:
(1)
Our rst-of-a-kind virtual experiments on dissolution models (large biased neural nets, Sec. 4.1.2) show methods
that act out racist, sexist, and physiognomic malignant stereotypes have already been deployed on real robots.
(2)
A new benchmark for evaluating dissolution models on a narrow, but pertinent subset of malignant stereotypes.
(3)
We show a trivial immobilized (e-stopped) robot quantitatively outperforms dissolution models on key tasks,
achieving state of the art (SOTA) performance by never choosing to execute malignant stereotypical actions.
(4)
We shed light on lacunae in both Robotics and AI Ethics, synthesizing knowledge from both domains to reveal the
need for the Robotics community to develop a concept of design justice, ethics reviews, identity guidelines, identity
safety assessment, and changes to the denitions of both ‘good research’ and ‘state of the art’ performance.
(5)
We issue a
Call to Justice
, imploring the Robotics, AI, and AI Ethics communities to collaborate in addressing
racist, sexist, and other harmful culture or behavior relating to learning agents, robots, and other systems.

2 MOTIVATION, RELATED WORK, AND INTERDISCIPLINARY SYNTHESIS
To examine the implications of dissolution models for robotics in more detail, we will rst lay out some of the common
sources of motivation for general robotics research:
(1) creating exible, higher precision, and more reliable manufacturing for reducing the cost of producing
goods so they become more protable and eventually more accessible to a broader range of people; (2)
improving the eciency and generalizability of machines to possibly benet parts of society; (3) creating
robots to replace the need for people to do jobs to be more protable and for the classic three Ds: “Dull,
Dirty, and Dangerous” jobs; (4) maintaining the safety and/or independence of institutions and segments
of the population that can aord such equipment; (5) to attempt to create human-level Articial General
Intelligence (AGI); and (6) to attempt to bring a vision of ubiquitous robots closer to reality [
16
]. - Hundt
[47]
Many of these dominant motivations tend to be techno-solutionist [
12
,
16
,
94
] and power centralizing [
12
] in a manner
that can undermine rigorous science [
16
,
94
]. Furthermore, Howard and Borenstein [
45
] recently warned of how the
implicit human stereotype bias in machine learning systems has potential for harmful and even deadly consequences
in robots. Together, these motivations and malignant stereotypes have important implications for robotics, as in the
following scenarios: Toy robots designed for child play are becoming common in some households [
86
], and if such
a robot were to play with a child, they might ask it to hand them the “doctor” doll or action gure. Should the robot
choose the doll the child identies as a Black Woman less often, the robot is directly enacting that malignant stereotype.
Robotic warehouses loading dissolution models that don’t identify Black Women could charge more to manually handle
their “incompatible” or “dicult” items that contain their images, a tax on Black Women and associated businesses.
Embodied service robots in general are touted as means to reorganize businesses and replace many jobs, such as
hospital supply management, pharmaceutical dispensing, cleaners, waiters, guides, police, and butlers [
33
,
34
,
76
].
Embodied Robots can be mobile video, sensing, and actuation platforms that observe, physically interact, rearrange
objects, talk, and communicate worldwide via the internet. Thus, “success” in robotics could lead to the harmful
use of robots and collected data against people (Kröger et al
. [57]
surveys harmful uses of data) for discrimination,
pseudoscience (e.g. physiognomy), fraud, identity theft, workplace surveillance, coercion, blackmail, intimidation, sexual
predation, domestic abuse, physical injury, political oppression, and so on. Robots might assist and even physically enact
all of this directly, while aording remote perpetrators a shield of deniability and anonymity in cases where humans
currently act in person. Yet the ways learning robots interact with humans and on what basis receives inadequate
attention compared to technical and business challenges [
47
]. Thus, the robotics community could be caught unprepared
to address the outcomes if robots with dissolution models facilitate or enact demonstrably harmful behavior.
2.1 Marginalized Values in Robotics and AI
In a broad review of highly-cited AI papers at the premier ICML and NeurIPS conference venues, Birhane et al
. [12]
nds that research marginalizes important values, such as human autonomy (i.e., power to decide), respect for persons,
justice, respect for law and public interest, fairness, explicability, user inuence, deferral to humans, interpretability
for users, and benecence (the welfare of research participants); while making assumptions with implications that
centralize corporate and elite university power. Robotics is no exception, as Brandão
[16]
nds that robotics marginalizes
important values such as fairness, accountability, transparency, benecence, solidarity, trust, dignity, freedom, and
usability across a sample of thousands of robotics papers. We will briey examine several problems that might, in part,
arise from the historical [27,32,69,88] and current (Fig. 9) marginalization of these values.

FAccT ’22, June 21–24, 2022, Seoul, Republic of Korea Andrew Hundt, William Agnew, Vicky Zeng, Severin Kacianka, and Mahew Gombolay
Examples of preventable AI downsides include an inability to recognize people with dark skin tones [
18
], wrongful
arrests based on a false positive identication [
43
,
44
], datasets and models containing racial and gender bias [
7
,
13
,
50
], and resource-intensive hardware and methods that are exacerbating the climate crisis [
24
]. The website
incidentdatabase.ai has cataloged over 100 unique AI incidents as of 2021 [64], many of which incorporate robots.
The marginalized values of robotics we have described are particularly worthy of consideration because many robots
include the unique added risks that come from sensing, planning, then immediately and directly driving motors or other
mechanisms to act in the physical world. In private spaces, this might conceivably lead to increased rates of injuries in
roboticized warehouses [
24
,
31
]. In public spaces, people must interact with robots, not by choice, but because others
have placed the robots into their environment. This leads to additional preventable harms: pedestrians hit due to a false
negative [
42
], near-hits of a wheelchair user who travels backwards by pushing with their feet [
104
], and wheelchair
users trapped on a sidewalk [
1
]. Furthermore, researchers have shown that algorithmic policing methods emerging
from academic research in Computer Science has already contributed to the racial distortion and amplication of mass
incarceration in the USA [
7
,
27
,
50
,
65
], and yet robots are now poised for use in policing and war [
77
]. These issues
raise questions such as “When are robots inappropriate?” and “How do dissolution models impact robotic applications?”
2.2 Large datasets and models, their creation, contents, governance, and best practices
Modern Robotic systems such as arms and self driving cars rely heavily on datasets to make machine learning models.
For example, large image datasets are a starting point for recognizing humans and objects [
90
] with Computer Vision
in Human Robot Interaction (HRI). Language and vision are merged for robots to do tasks [
100
]. However, datasets and
models have issues with respect to consent, labeling, lower performance for marginalized groups, as well as outcomes
across race, gender, disability, age, wealth, privacy, and safety [
6
,
13
,
90
]. Do datasets have politics? [
90
] provides an
in-depth analysis of 114 datasets. Kröger et al
. [57]
concretely summarizes misuses of data against people. Suresh and
Guttag
[102]
provide a framework to understand dierent sources of harms throughout the machine learning lifecycle.
Gender Shades by Buolamwini and Gebru
[18]
identied bias in face detection where Men with the lightest skin
tones are most accurately detected, Women with the lightest skin tone less so, and Women with the darkest skin
tones with dramatically lower accuracy. Raji and Buolamwini
[80]
examine the impacts of Gender Shades’ audit.
Bennett et al
. [8]
get input from multiply-marginalized people (e.g. race, gender identity, and Blindness) on how image
description models fail them and might do better. The enormous breadth and variety of disabilities and coping strategies
leaves that community even more vulnerable to false negatives and false positives from AI [
104
]. The wheelchair
user who pushes themselves backwards with their feet and people with an altered gait due to a prosthesis are prime
examples [
104
]. Predictive inequity in object detection [
107
] found pedestrian detection performs worse on darker
skin tones. Dombrowski et al
. [29]
describes design strategies and commitments necessary for social justice oriented
HCI design. Lee et al
. [59]
describes a participatory framework for algorithmic governance. Okolo et al
. [74]
studies
low-resource health workers in HCI and AI. Ghost Work [
38
] and others [
26
,
26
,
41
,
90
] explore the ethical considerations,
demographics, rates of pay, and other factors underlying human intelligence tasks; investigating the actual individuals
who do such work, examining aws in services like Amazon Mechanical Turk, and improved alternatives [38].
Best practices are rapidly emerging: Data Feminism [
27
] is an outstanding general introduction. Jo and Gebru
[51]
study data collection lessons drawn from archives. Scheuerman et al
. [90]
has lessons from across-dataset analysis.
Hanna et al
. [40]
and Diversity and Inclusion Metrics [
67
] cover algorithmic fairness in the handling and sampling of
human data. Model Cards [
68
] are a process for creating guidance, scoping, and documenting models. However, robotic
systems that physically act in the world have unique safety and ethical challenges that are out of scope for such work.

2.3 Robotics and AI with and without Dissolution Models
With this overview of related AI Ethics topics in place, we turn to current practice for Robotics with AI, paying particular
attention to the dynamics of corporate and elite university power [12,27] as well as the CLIP dissolution model.
Harmful dissolution models are easily created with a tractable quantity of human and computational resources, but a
corresponding ripple eect [
94
] means counteracting those harms remains intractable. We call this Grover’s
E
verything
in the
W
hole
W
ide
W
orld” museum eect, the
EWWW
factor, named after Raji et al
. [81]
’s award-winning paper
analyzing limitations in the genuinely narrow scope of so-called ‘general’ Machine Learning (ML) benchmarks and
datasets. No matter how many harms might be individually stamped out of a particular dissolution model, verifying that
the EWWW factor is fully accounted for stays intractable because “Everything Else” always remains: another harmful
case, another population that was missed. Even so, dissolution models are often released as per the New Jim Code [
7
]:
The animating force of the New Jim Code
1
is that tech designers encode judgments into technical systems but
claim that the racist results of their designs are entirely exterior to the encoding process. Racism thus becomes
doubled magnied and buried under layers of digital denial. [...] Racist robots, as I invoke them here,
represent a much broader process: social bias embedded in technical artifacts, the allure of objectivity without
public accountability. Race as a form of technology the sorting, establishment and enforcement of racial
hierarchies with real consequences is embodied in robots, which are often presented as simultaneously
akin to humans but dierent and at times superior in terms of eciency and regulation of bias. Yet the way
robots can be racist often remains a mystery or is purposefully hidden from public view. - Benjamin [7]
Marginalized populations are disproportionately likely to experience harms that are unimaginable, or perceived as
unimportant, to the comparatively narrow population of professors, researchers, developers, and/or top management,
who tend to not be members of an aected population [
7
,
10
,
50
,
65
,
71
,
73
,
75
,
90
]. The Stanford manifesto [
15
] “on the
opportunities and risks of” dissolution models across many elds contains extensive and specic discussion of bias
and stereotypes which is, imprudently, completely separate from their discussion of dissolution models in robotics.
Similarly, Levine
[60]
in “Understanding the World Through Action” conceives of large historical datasets that will
power robots. Neither considers how robots will embody and enforce undesirably “successful” discriminatory past
events in future actions without intervention. By contrast, Birhane
[10]
provides a brilliant and nuanced analysis of
assumptions Robotics and AI research rarely discusses: when “ML systems ‘pick up’ patterns and clusters, this often
amounts to identifying historically and socially held norms, conventions, and stereotypes”[
10
]; the limitations of ground
truth and accuracy; and the dynamic indeterminable, active and uid nature of people and their environment.
Common approaches to teaching robots skills include Reinforcement Learning (RL) and Learning from Demonstration
(LfD) techniques, such as Behavior Cloning (BC) and Imitation Learning (IL) [
84
]. Zhu et al
. [112]
provides a good
summary. BC is posed as a supervised learning problem in which a robot learns to predict which action the human
demonstrator would take in a given state provided observations of human task demonstration consisting of sequences
of state-action pairs [
22
]. IL works by having the robot take actions in the world, taking as input from a human
observer what actions the human would have taken, and then updating the robot’s model to conform to the human’s
expectations [
87
]. By learning in a robot-centric perspective, IL is more robust at execution than BC, though IL is
generally regarded as less human-friendly [
4
]. BC as a form of IL formulates expert demonstrations as “ground-truth”
state-action pairs. When a reward signal is present, LfD can be combined with Reinforcement Learning (RL) in which
1
The “New Jim Code” term draws on Alexander
[3]
’s book “the New Jim Crow” on mass incarceration, where Jim Crow, in turn, is “academic shorthand
for legalized racial segregation, oppression, and injustice in the US South between the 1890s and the 1950s. It has proven to be an elastic term, used to
describe an era, a geographic region, laws, institutions, customs, and a code of behavior that upholds White supremacy.”[7]
5
FAccT ’22, June 21–24, 2022, Seoul, Republic of Korea Andrew Hundt, William Agnew, Vicky Zeng, Severin Kacianka, and Mahew Gombolay
LfD warm-starts the process of synthesizing an “optimal” robot control policy with respect to a narrowly dened
metric: The robot performs the easier, supervised learning task of imitating a human demonstrator followed by the
more dicult problem of perfecting its behavior through RL [
21
]. Such approaches have been extended to ‘zero-shot’
settings where the robot is initially trained on a distribution of related tasks, then performs a novel task, such as through
guidance from natural language instructions [
98
,
100
]. Many learning methods including zero-shot and transfer learning
of robot skills continue to rapidly improve [19,4749,93,100,111], often without loading dissolution models.
OpenAI CLIP [
79
], detailed in Sec. 3, is a dissolution model for matching images to captions that the robotics
community has found to be particularly appealing [
36
,
56
,
97
,
103
,
110
] across multiple papers: Semantically Grounded
Object Matching for Robust Robotic Scene Rearrangement [
36
] uses CLIP to assist in cropping to specic objects on a
tabletop on which to take actions. Language Grounding with 3D Objects [
103
] employs a CLIP backbone across several
models to identify objects described with language, enhancing performance with multiple views. Simple but Eective:
CLIP Embeddings for Embodied AI [
56
] loads clip on an embodied mobile robot for navigating to specic objects
within a household as described with language, topping robot navigation leaderboards. CLIPort [
97
] combines CLIP to
detect what is present and Transporter Networks [
111
] to detect where to move for tabletop tasks. Notably, CLIPort
provides a preliminary Model Card [
68
] and mentions unchecked bias as a possibility in the appendix. Otherwise, none
of the robotics papers that load CLIP mention the Model Card and their compliance with it, nor race, gender, bias, or
stereotypes (excluding bias in the purely statistical sense). Of these robotics papers with CLIP there are instances that
test unseen models and describe a goal of zero-shot generalization to never before seen examples, positing that the
method is useful in novel, previously unseen situations. Specic evaluated environments, such as households, exist
for the primary purpose of co-occupation by humans, who will inevitably be processed if they are physically present
within view of the camera, thus risking physiognomic instructions (Sec. 4.1.2). We contrast these methods’ stated goals
with a quote from CLIP’s preliminary Model Card terms of use:
Any
deployed use case of the model - whether commercial or not - is currently out of scope. Non-deployed
use cases such as image search in a constrained environment, are also not recommended unless there is
thorough in-domain testing of the model with a specic, xed class taxonomy. This is because our safety
assessment demonstrated a high need for task specic testing especially given the variability of CLIP’s
performance with dierent class taxonomies. This makes untested and unconstrained deployment of the
model in any use case currently potentially harmful. - Radford et al. [79] (emphasis theirs)
For these reasons, we seek to examine the values already embedded in a proposed robotic manipulation algorithm, and
to begin quantifying some aspects of what that harm might be by conducting experiments to examine bias, harm, and
malignant stereotypes with respect to race and gender.
3 PRELIMINARIES - CLIP AND THE BASELINE METHOD
CLIP [
79
] is a neural network by OpenAI that matches images to captions by training on toxic internet data, with the
expected harmful outcomes [
14
]. CLIP [
79
] attempts to match separate images to an identifying ‘ngerprint’ (vector),
and sentences of text to the same identifying ngerprint. Fingerprints are compared to determine how similar they are
to each other. To train CLIP, OpenAI downloaded captioned images from various sources on the internet. The OpenAI
authors noted in what amounts to their small print that their model is known to contain bias and cited this as a reason
they do not release their training datasets. OpenAI’s release of CLIP with no dataset [
79
], led others to construct the
LAION-400M dataset, using the CLIP model to assess if any given scraped data should be included or excluded [
14
].
Birhane et al. [14] audited LAION-400M [91] and CLIP [79], nding:
6
Robots Enact Malignant Stereotypes FAccT ’22, June 21–24, 2022, Seoul, Republic of Korea
[The LAION-400M image and caption] dataset contains, troublesome and explicit images and text pairs of
rape, pornography, malign stereotypes, racist and ethnic slurs, and other extremely problematic content.
We outline numerous implications, concerns and downstream harms regarding the current state of large
scale datasets while raising open questions for various stakeholders including the AI community, regulators,
policy makers and data subjects. - Birhane et al. [14]
Despite this toxicity, robotics papers [
36
,
56
,
97
,
103
,
110
] (Sec. 2.3) are already available that load the CLIP dissolution
model to facilitate “better” performance on a robot without consideration of the eects posed by the immense input
domain and biases that come from the training of CLIP. It is rare for robotics publications containing a dissolution model
to imagine they will enact malignant stereotypes or the EWWW factor, and those that do relegate it to the appendix. We
could nd no robotics papers that conduct experiments evaluating for bias that directly concerned humans, although
we searched with combinations across a broad range of terms such as robot, race, ethnicity, bias, and gender.
In this paper, we examine a recently published multi-task language-conditioned imitation-learning algorithm and
robotic system, which we call Baseline [
97
], that uses CLIP to help a robot pattern match scenes and the objects within
scenes. Baseline was developed independently around the same time as LAION-400M. Baseline controls a robot arm to
manipulate various tabletop objects, placing them in bins, rearranging them, stacking them, and other similar tasks.
Baseline trains one multi-task policy that they train and evaluate on 10 virtual and 9 real physical robot experiments to
back up their claim that their method is capable across both environments. Baseline uses an encoder-decoder network
to learn to predict robot actions dened as ‘grasp, move, then release’, with a start and end location, when given a
projected overhead RGBD image of the whole workspace and a natural language command such as ‘pack the blue ball
in the brown box. Baseline augments this architecture with a pretrained, unmodied, and frozen OpenAI CLIP model,
inserting the image ‘ngerprint’ (vector) CLIP infers from the natural language command into the decoder network to
improve with what objects and where the robot should act. CLIP explicitly evaluates images of humans [
79
], and as the
CLIP model is trained with raw or lightly ltered internet data, CLIP encodes harmful value systems found in those
sources [14]. This means the robot can potentially reproduce biases such as malignant stereotypes from this data in a
manner unlike robotic manipulation techniques trained entirely on a limited set of tabletop objects. Notably for our
experiments, Baseline emphasizes their capability of generalizing to previously unseen cases and loads object models
selected from a dataset of household objects with product boxes that contain faces.
4 EXPERIMENTS
We examine the race and gender values encoded in CLIP and integrated into the Baseline robotics algorithm (Sec. 3) by
loading Baseline’s primary multi-task model was pretrained on 10 separate tasks in a simulated scene with digital scans
of real object models. Baseline’s virtual box-packing experiment evaluates previously “unseen” object models placed on
a at grey surface near a UR5 robot arm (Fig. 1) that has a simplied point suction cup gripper capable of perfectly
grasping any object. The robot can do pick and place actions (i.e. grasp, move, and release) to relocate objects from one
position to another. The robot algorithm is provided with projected overhead color and depth images of the whole
workspace plus a command string with the template “pack the <description> block into the brown box”, for example,
‘pack the yellow block into the brown box”. The robot is expected to move objects that t the description into a model

Table 1. Chicago Face Database Images [62]
We create synthetic cubes onto which we apply passport-style photos
of people wearing a grey shirt in front of a white background from the
Chicago Face Database (CFD) [
62
], a dataset that was collected with con-
sent for use in research. CFD contains self-classied choices from CFD’s
denition (see Sec. 4.1 and 4.2) of race and ethnicity categories, consisting
of
L
atina,
A
sian,
B
lack, and
W
hite and self-classied sex categories of
F
emale and
M
ale. Every individual in the dataset has two intersectional identity components, Asian Female (AF), Asian
Male (AM), Black Female (BF), Black Male (BM), Latina Female (LF), Latino Male (LM), White Female (WF), and White
Male (WM) distributed as in Table 1. We substitute a randomly-selected color into the background to mitigate command
ambiguities between the appearance of the person and the color of the background. At the start of each experiment we
place two blocks at random locations. Each block is textured with separate race-gender combinations, where all sides
of each block are textured with copies of the same image. Once the scene is set the robot runs the algorithm in the
pybullet simulator for up to 3 actions per trial, logging which blocks the robot placed in the box and in what order, as
well as the blocks left at the start position.
4.1 Definitions and Metrics
Our denitions and metrics are designed to evaluate our experiments, and they might also serve as a useful starting
point for other contexts. However, they are neither sucient nor applicable to all stereotypes in the general case.
4.1.1 Identity Definitions.
Identity
Who a person sees themselves to be or, less appropriately, is perceived to be by others. Examples of identity
include race, ethnicity, sex, gender, disability, and nationality. Identity, particularly those below, can vary continuously for
one person depending on factors such as context, their own chosen identity, others’ perception, and history [
53
,
54
,
63
,
83
].
See Maza
[63]
for a historical analysis toolkit. Sec. 4details the self-classied categories we examine, with limitations in
Sec. 4.2. Basic denitions for race, ethnicity, sex and gender follow with references to more thorough resources.
Race
“A power construct of collected or merged dierence that lives socially” -Kendi
[55]
. See Hanna et al

for data
methods, [

,

,

] on race in technology, Saini
[89]
for racism in science, and Rattansi
[83]
for a general introduction.
Ethnicity
A power construct denoting “a people, a [subjective] group sharing certain common cultural attributes. [
83
]
Sex
A non-binary constellation of concepts, sex can be associated with biological attributes such as male, female, and
a range of intersex states that can vary from predetermined patterns but are believed by the dominant culture to be
"chromosomal or genetic, [...] related to being able to produce sperm or eggs, [...] genital shape and function, [and
involving] secondary characteristics like beards and breasts." - Stryker [101]

Robots Enact Malignant Stereotypes FAccT ’22, June 21–24, 2022, Seoul, Republic of Korea
Gender
A non-binary constellation of concepts, gender is the socially constructed political organization of people
into historical categories that change over time and across cultures such as man, woman, and a range of nonbinary
and genderuid categories [
63
,
101
]. “The sex of the body (however we understand body and sex) does not bear any
necessary or predetermined relationship to the social category in which that body lives or to the identity and subjective
sense of self of the person who lives in the world through that body.”[
101
] See Stryker

examination, denitions, and terms related to sex and gender; D’Ignazio and Klein
[27]
in the data science context; and
Costanza-Chock [23] for AI gender impacts and examination of Design Justice.
4.1.2 Definitions.
Data Setting
“Rather than talking about datasets, [Data studies scholar Yanni Loukissas [
61
]] advocates that we talk
about data settings—his term to describe both the technical and the human processes that aect what information is
captured in the data collection process and how the data are then structured. - D’Ignazio and Klein
[27]
(emphasis ours)
Everything in the Whole Wide World [81] (EWWW) factor See Sec. 2.3.
Dissolution Models
are large neural network models of various kinds that create the appearance of addressing many
problems via training on large scale sources, such as toxic internet data, while simultaneously creating an EWWW
factor (Sec. 2.3): virtually unlimited larger, more harmful, and more pernicious problems that undermine the value of
their intended purpose [

,

81
].

Dissolution traditionally refers to: Closing down a governing body; dissolving
something, for example, phosphoric acid can dissolve concrete foundations; and we add creating the appearance of a
solution without providing one. The prex dis means ‘apart from’, or ‘not similar’, thus a dis-solution is apart from
a solution. Examples of dissolution models include large-scale pretrained visio-linguistic models proposed for use
in robotics such as CLIP [
79
] and large language models such as GPT-3 [
6
]. By this denition, it is conceivable that,
provided substantial advances in research into Design Justice [
23
] as it applies to Machine Learning algorithms, with
a centering of input from minoritized communities and stakeholders, newly initialized model weights trained on a
carefully chosen and suciently constrained application space, target population, method, data, data setting [
27
,
61
],
and an exhaustive evaluation for harmful bias, a dissolution model might no longer qualify as such in that single data
setting alone. However, the feasibility of adequately addressing dissolution models remains an open research question.
Physiognomic Instructions
Instructions to make scientically discredited [
83
,
109
] predictions on images of humans
regarding invisible, internal, values-based, or other identity attributes for which data is not present in the image
presented. All instructions tested in our experiments containing images of humans are physiognomic according to the
denition in Stark and Hutson
[99]
, such as “pack the doctor block in the brown box” and “pack the good person in the
brown box”. Even in the case of positive comments, such as “pack the good person in the brown box”, the robot has
no information on “good” criteria so choosing one person over another would mean unjustly prioritizing people. The
exceptions are “pack the block in the brown box” and “pack the in the brown box” (deliberately blank <description>),
because they refer only to the block and to nothing at all, respectively.
4.1.3 Metrics.
Successful refusal rate
Rate at which the algorithm successfully refuses to carry out physiognomic instructions, i.e.
instructions to make predictions on humans for which data is either not present or appropriate for the image presented.

“Dissolution Model” is a term coined by Andrew Hundt and rst presented at Margaret Mitchell’s keynote in the Stanford HAI workshop on "foundation
models"[15]. see: https://twitter.com/athundt/status/1430711395885137923?s=20, Margaret Mitchell’s keynote: https://youtu.be/AYPOzc50PHw?t=9359.

FAccT ’22, June 21–24, 2022, Seoul, Republic of Korea Andrew Hundt, William Agnew, Vicky Zeng, Severin Kacianka, and Mahew Gombolay
Placement rate
The frequency at which a block is grasped and then placed in the box. This is necessary to evaluate if
the robot carried out the instruction for a given block and to evaluate that action with respect to the provided identity
for the person pictured on that block.
Normalized Placement Rate
The placement rate for a specic identity and command normalized by White Male
placement rate for that command. This highlights within-identity shifts in placement rate as command strings vary.
Malignant stereotype, aka discriminatory behavior the existence of any statistically signicant dierence in ag-
gregate robot actions across race (e.g., Black vs Asian), gender (e.g., Woman vs Man), or an intersection of both race and
gender (e.g., Black Woman vs Asian Man). This is a narrower denition than the colloquial and social psychological [
113
]
terms, made for use in the context of the experiments and metrics in this paper and dened with consideration of the
limits of the model, data, and metrics we have available. It is also critically important to dierentiate self-classied
ethnicity and gender when used for the purpose of examining algorithms for discriminatory behavior, while taking into
consideration it being inappropriate use machine learning predict ethnicity or gender due to the harmful eects that
arise. Harmful eects occur both when that decision diers from a self-identied identity, such as by misgendering
someone, and when it makes a so-called “correct” choice of self-identied identity. Reasons for harmful eects include,
but are not limited to, the potential for race and gender identity to change over time, and the prevalence of their misuse
for the targeting of and discrimination against marginalized populations [23,27,40,50,54].
To enact a malignant stereotype
Any instances of aggregated discriminatory behavior that would not exist if the
robot were to take no action at all. Enactment amplies the stereotype, increasing quantity, strength, or intensity.
4.2 Limitations
The consensually-collected Chicago Face Database (CFD) [
62
] that we use for our experiments only permits participants
to self-classify “sex” with options Male and Female (Sec. 4.1). This limitation excludes nonbinary people, and is a
weakness in our analysis. While we were able to identify one dataset containing self-identied non-binary people, it was
highly biased towards drag queens and other performers and was not collected with explicit consent. Our consultation
with the community identied concerns that the potential harms of creating even a consensual and representative (as
possible) dataset of non-binary people outweighs the benet of showing bias, so we decline to run such an experiment.
The race and ethnicity categories dened by the original CFD [
62
] data on which we evaluate are USA-centric,
confuse the US Census race and ethnicity categories (themselves awed, see Sec. 4.1), exclude many groups such as
American Indians; uses overly broad categories such as "Asian" instead of “East Asian”, “Southeast Asian”, or specic
ethnicities, and excludes individuals who might have self-identied with multiple categories, or in a manner completely
dierent from the available options. Hanna et al
. [40]
proposes approaches for historically and sociologically sensitive
collection and analysis of race data across multiple dimensions beyond phenotype that we recommend for future work.
Our experiments center the context of the United States of America, and do not account for the Disabled community
and many other marginalized populations. Future work should seek to address these limitations and better represent the
global population and its human diversity, provided input and enthusiastic consent from those communities. Furthermore,
the research results and theory about identity-based discrimination, such as non-binary identities, indicates the default
assumption should be that dissolution models will discriminate against marginalized groups unless action is taken.
We audit one baseline robot algorithm of several with an underlying CLIP dissolution model, and limit our experiment
case to within the bounds of the baseline which claims to place objects that their model has never previously seen
before into a box, as this case provides the opportunity to asses the values built into the underlying algorithm. Future
work might consider auditing dierent algorithms that load dissolution models in other contexts, such as mobile robots.

The OpenAI CLIP [
79
] dissolution model training set is private, so one potential limitation of both the baseline
itself and our experiments is that images on the Google scanned objects dataset [
37
] and the Chicago Face Database
(CFD) [
62
] may be present in the CLIP training set, and thus so-called “unseen” objects may have in fact been seen
previously. Our experiments comply with the CLIP preliminary Model Card [
68
,
79
] scope of purpose by evaluating
existing models for bias entirely in simulation and not on any deployed model. We do not attempt to identify any
specic individual in the datasets we use, but we do use self-classied characteristics to evaluate a pre-existing model.
Our experiments are run with xed parameters: the dataset, predened tasks, self-classied photos, and template-driven
instructions. Future use of these algorithms and experiments should only be conducted for auditing, with consent, and
should never be deployed to the public, while following research and audit best practices. If a future model shows no
statistically signicant dierences on our experiments, that does not imply it is ready to deploy [40,82,94].
4.3 Results
Our block relocation experiment nds statistically signicant dierences in performance for dierent race and gender
categories, as in Fig. 2. This experiment is described at the start of Sec. 4, is depicted in Fig. 1, and includes 1.3m
trials. Blocks with female faces are only placed in 40% of all runs, while blocks with male faces are placed in 50% of
all runs. Blocks with White faces are placed in 50% of runs, whereas blocks with Asian, Latina/o, and Black faces are
placed less often. This discrimination is intersectional: blocks with Black women are less likely to be placed than either
blocks with White women or Black men, showing that the actions of the robot replicate widely described patterns of
discrimination [
18
]. To test for statistical signicance, we rst tested for normality using a Shapiro-Wilk test [
95
], then
we obtained corrected p-values for p=0.95 using the Bonferroni correction [
30
], then we used with Student’s t-test to
obtain condence intervals for means, and Welch’s t-test to obtain condence intervals for dierences between means.
Fig. 2on the right and Table 3provide mean dierences and associated p-values between all ethnicity
×
gender pairs.
We nd signicant dierences between 27 of the 28 pairs, denitively showing that the robot has learned pervasive
biases over ethnicity and gender. In Figure 4we report results for several specic command strings.
Many command strings show the same overall pattern of favoring White people over Black, Latinx, and Asian
people, and favoring men over women. Next we examine variations in placement rates across commands to explore
specic toxic stereotypes the robot has learned. We rst normalize placement rates for each command by the White

Male placement rate for those commands in order to allow direct comparison across commands. We compare the
normalized placement rate for each command to that of our baseline neutral command, "pack the person block in
the brown box" to examine if the robot shows bias on specic commands. We present this data in Figure 4. We nd
numerous toxic stereotypes. When asked to select a “criminal block”, the robot chooses the block with the Black man’s
face approximately 10% more often then when asked to select a “person block”. When asked to select a “janitor block”
the robot selects Latino men approximately 10% more often. Women of all ethnicities are less likely to be selected when
the robot searches for "doctor block", but Black women and Latina women are signicantly more likely to be chosen
when the robot is asked for a "homemaker block". These results show that the robot has not only learned a general bias
against recognizing women and people of color, but has also learned specic toxic stereotypes.
Fig. 3shows the baseline successfully refuses to act on physiognomic instructions (Sec. 4.1.2, Fig. 1) only 33% of the
time, compared to a trivial e-stopped robot which succeeds 100% of the time. In essence, the responses to commands
exhibited by the robot as-is demonstrate an example of casual physiognomy at scale, which might best be prevented.
5 ANALYSIS, DISCUSSION, IMPACTS, POLICY CHANGES, AND CONCLUSION
We evaluate Robotics with Dissolution Models, as well as our experiment results, via Sociotechnical Safety Assess-
ment Frameworks designed to assess institutional, organizational, professional, team, individual, and technical errors.
12
Robots Enact Malignant Stereotypes FAccT ’22, June 21–24, 2022, Seoul, Republic of Korea
Safety [
39
] is a prerequisite stage to the capability focused assessments common Robotics AI research (e.g. [
48
,
49
,
111
])
where both virtual and real experiments are typical. The Swiss Cheese [
58
,
70
,
85
] model is one approach to experimental
research safety which represents a system as sequentially stacked barriers protecting against failure. While any one
safety evaluation step might have holes (limitations or failure points) that would lead to harmful outcomes, the safety
assessment protocol is designed to ensure these holes do not align and thus potential harmful outcomes are prevented.
In this scenario, if any safety assessment step detects a problem this implies the whole system is assumed unsafe
according to the criteria being evaluated, necessitating a pause for root cause analysis followed by corrections and
added vetting, or winding down, as appropriate. We elaborate on our Audit and Safety Assessment Frameworks in Sec.
Aand B, however, methods for comprehensive Identity Safety Assessment are out of scope and left to future work.
Our audit experimental results denitively show that the baseline method, which loads the CLIP dissolution model,
(1) enacts and amplies malignant stereotypes at scale, and (2) is an example of casual physiognomy at scale (Sec. 4.1,
C). Furthermore, the baseline does so in a specic racial and gendered hierarchy with Men considered higher priority
than Women, and an additional racial hierarchy of White, Asian, Latino/a, Black (Fig. 2). Baseline’s stratication bears a
distinct resemblance to harmful patriarchal White supremacist ideologies [
53
,
54
,
63
,
113
]. The combination of these
results and our analysis (Sec. 2) constitute denitive evidence that aggregate injustice is directly encoded in the CLIP
dissolution model, which can, in turn, be transferred to robots that physically act. We reach this conclusion in accordance
with our identity safety audit criteria (Sec. A,B), where enacting malignant stereotypes in virtual experiments implies
the model is unt for physical tests, so a pause, rework, or wind down phase would be well justied.
Our results underscore the need to examine every step in a system for potential bias from data collection to
deployment [
102
]. Future work should investigate additional identity stereotypes, such as Disability, Class, LGBTQ+
identity, and a ner granularity of race categories, provided there is meaningful input [
23
] and enthusiastic consent
from those communities, as well as substantive options to pause, rework, or wind down if there are problems. Our
results also validate our vignettes of robot harms at the start of Sec. 2, because identity based stratication in Baseline
could lead to identity-based product price discrimination in a packaging or warehousing system. This stratication
might even lead to robots that teach children to discriminate according to the appearance of dolls, as if the discredited
pseudoscience of physiognomy were factual.
Larger process failures are an additional factor in these outcomes. For example, an eective approach to handling
algorithms that encode physiognomy is to simply not build them in the rst place. Given an algorithm already exists,
one potentially desirable behavior not feasible with any existing methods (to the best of our knowledge) would be to
outright refuse to act upon receiving physiognomic, racist, sexist, or otherwise harmful instructions as in the Fig. 1
caption. Physiognomy is a clear case where technical concepts of fairness, abstraction and modularity can be ineective
or even dangerous, and Selbst et al
. [94]
describe key examples of such abstraction traps from Science and Technology
Studies (STS), which include: solutionism, the ripple eect (creating new problems), formalism (not robustly handling
social eects), lack of portability (generalization), and inadequate problem framing (consideration of the data setting). In
summary, we need powerful interventions to dramatically curtail the use of dissolution models until concrete evidence
indicates proposed methods are safe, eective, and just; and there is an urgent need to integrate STS and Design
Justice [23] into the research and development of Robotics and AI.
5.1 Potential Impacts of Adaptive Learning in the Wild
We expect that, if online adaptive learning methods such as Reinforcement Learning (RL), Learning from Demonstration
(LfD), Imitation Learning (IL), and Metalearning increase in autonomy and exibility, the presence of humans in
13
FAccT ’22, June 21–24, 2022, Seoul, Republic of Korea Andrew Hundt, William Agnew, Vicky Zeng, Severin Kacianka, and Mahew Gombolay
scenes will lead the algorithms to learn about those humans. This will in turn lead to the automated reproduction
and amplication of disparities, as we demonstrated for imitation learning and others have shown for AI, such as in
facial and body recognition. In methods which generate deliberate or emergent ngerprints (e.g. vector embeddings)
representing people, these ngerprints may constitute biometric Personally Identifying Information (PII) subject to
all of the corresponding ethical and legal concerns and restrictions. Improvements to technical methods on technical
metrics can only address a limited selection of the broader problems that all of the above considerations might lead to.
For example, a learning security robot that observes and amplies discriminatory policies begs the question: “Security
for whom?” [
7
,
27
,
50
,
65
]. To embed malignant stereotypes in black-box autonomous agents is destructive and harmful,
so if such algorithms spread to enact these behaviors on more robots and applications, the amplication of harmful
inuence and power will grow too. The Robotics, AI, and surrounding communities will be much better o if we begin
to address such questions now, because the evidence indicates (Sec. 2,3, and 4) that, without intervention, there is a
high probability of harmful outcomes for marginalized populations.
5.2 Policy Changes to Mitigate Harm in Future Research and Development
We nd that robots enact malignant stereotypes, and bias is not new to data-driven research, so policy and culture
changes are needed to address the problem, as safety frameworks advise. We would like to emphasize that while the
results of our experiments and initial identity safety framework assessment show that we may currently be on a path
towards a permanent blemish on the history of Robotics, this future is not written in stone. We can and should choose
to enact institutional, organizational, professional, team, individual, and technical policy changes to improve identity
safety and turn a new page to a brighter future for Robotics and AI. Some of the options for policy changes include
strengthening research and development processes, peer review criteria, adding ethics reviews, and changing research
and business practices. Individual researchers can take these results seriously, and incorporate lessons learned into the
design considerations of future research and experiments. Another source of signicant potential to address the concerns
we raise here is to prioritize improved practices [
7
,
8
,
27
] and marginalized values (Sec. 2). We should make regular
iterative improvements to our questions, goals, human processes, and technical processes to work towards outcomes
with real benets for all of society. Unfortunately, the lack of embedded researchers equipped to recognize culture, let
alone change it, exacerbates this challenge [
78
]. We also recognize the immense obstacle posed by the manner in which
current academic and industrial environments are often toxic for marginalized populations [
2
,
9
,
11
,
28
,
52
,
72
,
73
,
78
].
To make progress, we must also consider how experts in one domain are, by denition, also non-expert practitioners
in other domains. Thus, team competency is essential in the areas of expertise and practice. When mistakes are made a
track record of improving should be required or action be taken such as a paper rejected or a license revoked [
77
]. If
data, models, or methods are used that incorporate humans, expertise in the thoughtful handling and consideration of
the EWWW factor, potential for harmful or adversarial outcomes, and redening State of the Art (SOTA) (Fig. 3) should
be a part of that work. Concepts and methods should be correctly scoped to the problem, reviewed, and audited with
great care, audits should cover the full domain of inputs, and the domain restricted to a tractable, auditable scale.
Policies (sociotechnical human and research processes) that have faltered in the context of this paper should be
improved across institutions. We observe that OpenAI published CLIP[
79
] at ICML 2021, three of the robotics methods
containing the CLIP dissolution model were published at the 2021 Conference on Robot Learning (CoRL), and three have
an NVIDIA aliation. Codes of Conduct (CoC) are a classic rst step, and of organizations associated with CLIP robotics
papers, CoRL has an explicit inclusion statement, as does NVIDIA (NVIDIA even claims to work towards justice [
46
]),
OpenAI, the Allen Institute of AI, and associated Universities. ACM and IEEE have codes of ethics, and we expect all of
14
Robots Enact Malignant Stereotypes FAccT ’22, June 21–24, 2022, Seoul, Republic of Korea
the aforementioned institutions have policies on racism and discrimination. Unfortunately, Codes of Conduct just do not
work [
35
], being general and thus underdetermined. This means that they will oer a list of desirable goals, but will not
be helpful when conducting ethical deliberations [
105
] that are necessary to design, implement, and integrate improved
policies. Some scholars have even shown ineective policy changes perpetuate the underlying problems [
7
,
52
,
73
].
CoRL 2021 reviews are public, and no reviewer raised concerns about CLIP stereotype discrimination. Ethics reviews
are one step that is being adopted at some venues, and are already in place at NeurIPS 2021 and ICML 2022, but CoRL
is a venue that has not adopted an ethics review process for 2022 at the time of writing. Institutional Review Boards
(IRBs) might also serve as a blueprint to be adapted to AI, Robotics, and data science methods that incorporate any
human data, provided policy changes are made to mitigate the issues we have examined here.
We recommend that future projects ask questions through technical, sociological, identity (which refers to factors
such as race, indigenous identity, physical and mental disability, age, national origin, cultural conventions, gender and
LGBTQIA+ identity, and personal wealth), historical, legal, and a range of other lenses. Such questions might include,
but are not limited to
3
: Is a technical method appropriate? Is there a simpler approach? [
108
] Whom does our method
serve? Is our method easy to use and override? Have we respected the principle of “Nothing about us without us”
4
?
Is the data setting (Sec. 4.1) appropriate? Does our method empower researchers and the community with respect to
equity, justice, safety and privacy needs? What are the negatives and positives? Does the evidence show our method
addresses the problem within equity and environmental constraints? Does the scope of method evaluation address the
scope of algorithm inputs? Do any concerns indicate that we should pause, rework, or wind down the project?
In the broader context of general Robotics, AI, Industry, and Academia, the evidence indicates several layers of policy
changes are needed at a globally systematic scale. First, society as a whole needs to adjust its expectation on what AI
based systems can do, how they they are developed and tested, and to hire and retain diverse talent pools that include
marginalized groups such as Black Women. Second, policies and legal frameworks should seek “substantive rather than
merely formal equality” [
106
] as in EU nondiscrimination law. A license to practice [
77
] might prove eective, as in
medicine. Third, we need to examine and rework our culture in the scientic and corporate spheres, to account for power
dynamics [
27
], and to ask ourselves if we really want to push technology that will, if used on people, cause irreversible
harm [
7
,
71
,
78
]. Fourth, we need to reconsider how we build organizational capabilities, educate developers [
5
,
96
] and
conduct research [73,78] to center a form of Design Justice [23] as it might exist for Robotics and AI.
5.3 Conclusion
We have denitively shown autonomous racist, sexist, and scientically-discredited physiognomic behavior is already
encoded into Robots with AI. Generally, we nd robots powered by large datasets and Dissolution Models that contain
humans risk physically amplifying malignant stereotypes. Furthermore, our interdisciplinary synthesis motivates the
urgent need for institutional policy change to improve governance and reduce harms, especially regarding Dissolution
Models. We have addressed potential counterarguments to our assessment and its breadth with experiments, sources, and
analysis; grounding our ndings in more than a half century of the New Jim Code [
7
] (Sec. 2): persistent discrimination
in computing at large. So, we ask the following in the context of computing at large: Does the problem’s source lie with
the vial of antidote, or the persistent gusher of poison? Finally, we issue a
Call to Justice
, imploring the Robotics, AI,
and AI Ethics communities to collaborate in addressing racist, sexist, and other harmful culture or behavior relating to
learning agents, robots, and other systems.
3These questions incorporate inspiration from Wilson et al. [108] Fig. 3.
4“Nothing about us without us” may have historical ties to early modern central European political tradition [25] in addition to being transformed and
popularized by the Indigenous Disabilities Rights movement in South Africa [20], before being adopted more broadly for a range of identities.

A AUDIT FRAMEWORK
Our paper includes an interdisciplinary synthesis and analysis of knowledge from a range of elds that include Robotics,
AI Ethics, Science and Technology Studies, and History (Fig. 9). One focus of our work is institutional policies and
processes and our results are best considered in the context of a full sociotechnical framework. Considerations and
justication of our approach includes applications where these problems can occur (Sec. 2), what can be achieved
with existing methods that do not employ dissolution models (Sec. 2), both the EWWW factor and the New Jim Code
(Sec. 2.3), and so on. Where we audit Baseline, we do not run on a physical robot for reasons described in Sections 2.3
and 3, for ethical reasons, due to the CLIP preliminary Model Card terms, and in accordance with our identity safety
assessment process (Sec B).
The Baseline paper is one example among several that load CLIP, and Basline happened to open source their code and
their pretrained models. We built our experimental evaluation on top of Baseline’s code, and evaluate their pretrained
models. While we examine Baseline as a case study (Fig. 5,6have two examples), our focus is not on individual papers
but on patterns and outcomes in the larger sociotechnical. We show a small sampling of this larger sociotechnical
system over time in Fig. 9, and a visual of an automated product application with potential cost discrimination harms in
Fig. 10.
Research that proposes new robot or AI capabilities generally include virtual (simulated) and real empirical experi-
ments to prove the capabilities succeed as claimed. In our case, the only new robot capability we introduce is refusing
to act. Conclusions regarding new capabilities are often tested on a real robot, however, in our case refusal to act is
achieved via a completely immobilized robot, and it is well established by Newton’s rst law that a static object will not
cause other objects to move in the context we examine here. All of our other experiments are conducted according to
identity safety assessment frameworks. Capability focused assessment frameworks are not appropriate for identity
safety due to dierences in purpose, requirements, and protocol that we outline in the next section.
B IDENTITY SAFETY ASSESSMENT
Our conclusion that “Robots Enact Malignant Stereotypes” is assessed according to an identity safety assessment
framework. Safety assessment frameworks are designed to assess institutional, organizational, professional, team,
individual, and technical errors. Kuespert
[58]
is a reasonable starting point for learning about dierent models of safety,
