Dishonest behaviours such as tax evasion impose significant societal costs. Ex ante honesty oaths—commitments to honesty before action—have been proposed as interventions to counteract dishonest behaviour, but the heterogeneity in findings across operationalizations calls their effectiveness into question. We tested 21 honesty oaths (including a ba...

Internet users often neglect important security actions (e.g., installing security updates or changing passwords) because they interrupt users’ main task at inopportune times. Commitment devices, such as reminders and promises, have been found to be effective at reducing procrastination in other domains. In a series of online experiments ( \(n\,{\g...

Dishonest behaviors such as tax evasion impose significant societal costs. Ex-ante honesty oaths—commitments to honesty before action—have been proposed as useful interventions to counteract dishonest behavior, but the heterogeneity in findings across operationalizations calls their effectiveness into question. We tested 21 honesty oaths (including...

Regulators who aim to reduce administrative burdens often promote trust‐based policy instruments, such as legal affidavits or honesty pledges, as substitutes to traditional bureaucratic procedures. However, little is known on how the general public view such instruments, and whether people would actually comply with them, and under what circumstanc...

A common regulatory dilemma is determining how much trust authorities can place in people’s self-reports, especially in contexts with an incentive to cheat. In such contexts, regulators are typically risk averse and do not readily confer trust, resulting in excessive requirements when applying for permits, licenses, etc. Studies in behavioral ethic...

A common dilemma in regulation is determining how much trust authorities can place in people’s self-reports, especially in regulatory contexts where the incentive to cheat is very high. In such contexts, regulators, who are typically risk averse, do not readily confer trust, resulting worldwide in excessive requirements when applying for permits, l...

Behaviorally informed interventions are growingly used to nudge consumers for various goals. While consumers are usually the target of nudges, businesses are involved in nudges in two manners: either they are the target of the nudges (i.e., government-to-business, or G2B nudges), or they serve as “nudging agents" on behalf of government regulation...

Commitment devices are a technique from behavioral economics that have been shown to mitigate the effects of present bias---the tendency to discount future risks and gains in favor of immediate gratifications. In this paper, we explore the feasibility of using commitment devices to nudge users towards complying with varying online security mitigati...

Attitudes of public groups towards behavioral policy interventions (or nudges) can be important for both the policy makers who design and deploy nudges, and to researchers who try to understand when and why some nudges are supported while others are not. Until now, research on public attitudes towards nudges has focused on either state-or country-l...

Self-images are among the most prevalent forms of content shared on social media streams. Face-morphs are images digitally created by combining facial pictures of different individuals. In the case of self-morphs, a person's own picture is combined with that of another individual. Prior research has shown that even when individuals do not recognize...

With the worldwide implementation of students’ evaluation of teaching (SET), faculty attitudes and trust in students’ feedback as well as possible defensive (i.e., self-protective) motivations seem most relevant to the facilitation of the primary organizational goal of SET, namely, teaching improvement. A questionnaire—administered to 2241 faculty...

Despite recent advances in increasing computer security by eliminating human involvement and error, there are still situations in which humans must manually perform computer security tasks, such as enabling automatic updates, rebooting machines to apply some of those updates, or enrolling in two-factor authentication. We argue that present bias-the...

Malleability of preferences is a central tenet of behavioral decision theory. How malleable preferences really are, however, is a topic of debate. Do preference reversals imply preference construction? We argue that to claim preferences are construed, a demonstration of more extreme preference malleability than simple preference reversals is requir...

Software updates are critical to the performance, compatibility, and security of software systems. However, users do not always install updates, leaving their machines vulnerable to attackers' exploits. While recent studies have highlighted numerous reasons why users ignore updates, little is known about how prevalent each of these beliefs is. Gain...

Privacy decision making has been examined in the literature from alternative perspectives. A dominant “normative” perspective has focused on rational processes by which consumers with stable preferences for privacy weigh the expected benefits of privacy choices against their potential costs. More recently, a behavioral perspective has leveraged the...

The success of Amazon Mechanical Turk (MTurk) as an online research platform has come at a price: MTurk has suffered from slowing rates of population replenishment, and growing participant non-naivety. Recently, a number of alternative platforms have emerged, offering capabilities similar to MTurk but providing access to new and more naïve populati...

Purpose This paper aims to examine how reversibility in disclosing personal information – that is, having (vs not having) to option to later revise or retract personal information – can impact consumers’ willingness to divulge personal information. Design/methodology/approach Three studies examined how informing consumers they may (reversible cond...

People falsely believe that equal increases in vehicles' fuel efficiency (e.g., miles per gallon (MPG)) will result in equal fuel savings. Whereas previous research on this "MPG illusion" has focused on people's biased choices of upgrading vehicle models, it has not examined a more common situation, namely, estimating a given vehicle's fuel efficie...

The Security Behavior Intentions Scale (SeBIS) measures the computer security attitudes of end-users. Because intentions are a prerequisite for planned behavior, the scale could therefore be useful for predicting users' computer security behaviors. We performed three experiments to identify correlations between each of SeBIS's four sub-scales and r...

While individual differences in decision-making have been examined within the social sciences for several decades, they have only recently begun to be applied by computer scientists to examine privacy and security attitudes (and ultimately behaviors). Specifically, several researchers have shown how different online privacy decisions are correlated...

Although researchers often assume their participants are naive to experimental materials, this is not always the case. We investigated how prior exposure to a task affects subsequent experimental results. Participants in this study completed the same set of 12 experimental tasks at two points in time, first as a part of the Many Labs replication pr...

Despite the plethora of security advice and online education materials offered to end-users, there exists no standard measurement tool for end-user security behaviors. We present the creation of such a tool. We surveyed the most common computer security advice that experts offer to end-users in order to construct a set of Likert scale questions to...

A long list of myths has been attributed to faculty members regarding Student Evaluation of Teaching (SET) over recent decades. However, curiously, data has never been provided validating the claimed spread of these beliefs. In this study, we used a large and diverse sample (N=2,241) of faculty members from numerous institutions to examine the exte...

When asked to mentally simulate coin tosses, people generate sequences that differ systematically from those generated by fair coins. It has been rarely noted that this divergence is apparent already in the very 1st mental toss. Analysis of several existing data sets reveals that about 80% of respondents start their sequence with Heads. We attribut...

Confessions are people's way of coming clean, sharing unethical acts with others. Although confessions are traditionally viewed as categorical-one either comes clean or not-people often confess to only part of their transgression. Such partial confessions may seem attractive, because they offer an opportunity to relieve one's guilt without having t...

Some products and services (e.g., toll roads, Internet speed, electronics, etc.) offer consumers higher operating speeds that save time for completing a task (e.g., a journey or downloading files on the Internet). Consumers interested in such products have to judge the benefit of obtaining a higher speed product, in terms of time-savings, to decide...

Data quality is one of the major concerns of using crowdsourcing websites such as Amazon Mechanical Turk (MTurk) to recruit participants for online behavioral studies. We compared two methods for ensuring data quality on MTurk: attention check questions (ACQs) and restricting participation to MTurk workers with high reputation (above 95% approval r...

Background. The security and privacy communities have become increasingly interested in results from behavioral economics and psychology to help frame decisions so that users can make better privacy and security choices. One such result in the literature suggests that cognitive disfluency (presenting questions in a hard-to-read font) reduces self-d...

Research showed that given the opportunity, people behave dishonestly only to the degree that will allow them to maintain a positive self‐concept. These experiments did not include the probability of getting caught cheating, although in everyday life, this risk always exists. If it is shown that people behave more honestly when faced with an explic...

Confessions are people's way of "coming clean," sharing unethical acts with others. While confessions are traditionally viewed as categorical (one either comes clean or not), people might often confess to only part of their transgression. Such partial confessions might seem attractive, because they offer an opportunity to relieve one’s guilt withou...

The time-saving bias describes people's tendency to misestimate the time they can save by increasing the speed in which they perform an activity such as driving or completing a task. People typically underestimate time saved when increasing from a low speed and overestimate time saved when increasing from an already high speed. We suggest that this...

The time-saving bias describes people’s tendency to misestimate the time they can save by increasing the speed in which they perform an activity such as driving or completing a task. People typically underestimate time saved when increasing from a low speed and overestimate time saved when increasing from an already high speed. We suggest that this...

People generally overestimate the time they can save when increasing from a relatively high driving speed. Previous research suggested that people follow a Proportion Heuristic, calculating the time saved as the proportion of speed increase from the new higher speed. The present study suggests that drivers use another heuristic - the Percentage Heu...

Time-saving bias-people's biased judgments in estimating the time saved when increasing speed-has been found to strongly impact driving speed choices. However, this bias may be relevant only when the driver's motivation for increasing speed is to arrive sooner. If, on the other hand, the driver is motivated by the desire to experience thrill and se...

Naftulin, Ware, and Donnelly published the study about “The Dr. Fox lecture” in 1973, claiming that an expressive speaker who delivered an attractive lecture void of any content could seduce students into believing that they had learned. Over the decades, the study has been (and still is) cited hundreds of times and used by opponents of the measure...

This study explored multiple biases—the possibility that different biases would concurrently occur in a given situation, and each would exert its influence independently on people's judgments. The study focused on media bias through nonverbal (NV) behavior, where viewers judged an interviewed politician after they viewed the interview with a nonver...

Duplicate respondents across related experiments are a substantial problem for conducting programmatic research on AMT. In this tutorial, we provide a straightforward alternative that allows researchers who use Qualtrics to exclude workers who participated in a previous study. This approach allows researchers to exclude workers who have completed a...

Past research has shown that people judge a TV interviewee more favorably when the interviewer's nonverbal behavior toward the interviewee is friendly rather than hostile. This study examined whether students who participated in a media literacy course could be less susceptible to this media bias. Two groups of high school students (media literacy...

People make systematic and predictable mistakes regarding estimations of average speed and journey time. In addition, people have been shown to commit a time-saving bias by underestimating the time that can be saved when increasing from a low speed and overestimating the time that can be saved when increasing from a relatively high speed. These mis...

When drivers are asked to estimate how much time can be saved by increasing speed, they generally underestimate the time saved when increasing from a relatively low speed and overestimate the time saved when increasing from a relatively high speed. This time-saving bias has been demonstrated to affect drivers’ estimations of driving speed as well a...

When respondents answer paper-and-pencil (PP) questionnaires, they sometimes modify their responses to correspond to previously answered items. As a result, this response bias might artificially inflate the reliability of PP questionnaires. We compared the internal consistency of PP questionnaires to computerized questionnaires that presented a dif...

According to the time-saving bias, drivers underestimate the time saved when increasing from a low speed and overestimate the time saved when increasing from a relatively high speed. Previous research used a specific type of task --- drivers were asked to estimate time saved when increasing speed and to give a numeric response --- to show this. The...

According to the time-saving bias, drivers overestimate the time saved when increasing from an already relatively high speed and underestimate the time saved when increasing from a relatively low speed. This study examined the effect the time-saving bias may have on drivers' choice of speed using hypothetical situations. Drivers were presented with...

Health care resource allocation is a central moral issue in health policy, and opinions about it have been studied extensively. Allocation situations have typically been described and presented in a positive manner (i.e., who should receive medical aid). On the other hand, the negative valence allocation situation (i.e., who should not receive medi...

This research demonstrates the effect of framing on applicants' reactions to two personnel selection methods: undergraduate grade point average and personnel interview scores. Presenting a selection situation framed positively (to accept applicants) caused applicants to rate both selection methods more favorably relative to presenting them with an...

Previous research demonstrated that viewers’ judgments of an interviewee are influenced by the nonverbal behavior of the interviewer. In studies of this media bias effect, judges view a short political interview with a friendly or a hostile interviewer, and then rate their impressions of the interviewee, whose behavior remains identical in all cond...

This research demonstrates the effect of framing on justice judgments. Presenting identical allocation situations in different modes of accomplishing the resource allocation, resulting in either positive (benefits) or negative (harms) outcomes, affects justice judgments. Two independent studies revealed that participants judged non-egalitarian prin...
