In this study, we use computational methods for analyzing cultural transmission to examine the role of cognitive selection pressures on the evolution of narratives, the first use of computational phylogenetic analysis in the study of contemporary legends. It has been suggested that a number of biases in transmission may alter the content and struct...

This study uses urban legends to examine the effects of the social information bias and survival information bias on cultural transmission across three phases of transmission: the choose-to-receive phase, the encode-and-retrieve phase, and the choose-to-transmit phase. In line with previous research into content biases, a linear transmission chain...

This study used urban legends to examine the effects of a cognitive bias for content which evokes higher levels of emotion on cumulative recall. As with previous research into content biases, a linear transmission chain design was used. One-hundred and twenty participants, aged 16-52, were asked to read and then recall urban legends that provoked b...

Evidence for Emotional Content Bias in the Cumulative Recall of Urban Legends.

As the use of large language models (LLMs) grows, it is important to examine whether they exhibit biases in their output. Research in cultural evolution, using transmission chain experiments, demonstrates that humans have biases to attend to, remember, and transmit some types of content over others. Here, in five preregistered experiments using mat...

Conspiracy theories allege secret plots between two or more powerful actors to achieve an outcome, sometimes explaining important events or proposing alternative understandings of reality in opposition to mainstream accounts, and commonly highlight the threat presented by the plot and its conspirators. Research in psychology proposes that belief in...

During the 2020 US presidential election, conspiracy theories about large-scale voter fraud were widely circulated on social media platforms. Given their scale, persistence, and impact, it is critically important to understand the mechanisms that caused these theories to spread. The aim of this preregistered study was to investigate whether retweet...

Cultural evolution theory proposes that information transmitted through social learning is not transmitted indiscriminately but is instead biased by heuristics and mechanisms which increase the likelihood that individuals will copy particular cultural traits based on their inherent properties (content biases) and copy the cultural traits of particu...

Conspiracy theories provide explanations of important events or circumstances which allege a secret plot between two or more powerful actors as the salient cause, and commonly highlight the threat presented by the plot and its conspirators. Given the importance of threat in conspiracy theories, an interest in obtaining threat-related information mi...

We conducted a nationally representative survey of parents’ beliefs and self‐reported behaviors regarding childhood vaccinations. Using Bayesian selection among multivariate models, we found that beliefs, even those without any vaccine or health content, predicted vaccine‐hesitant behaviors better than demographics, social network effects, or scien...

During the 2020 US presidential election, conspiracy theories about large-scale voter fraud were widely circulated on social media platforms. Given their scale, persistence, and impact, it is critically important to understand the mechanisms that caused these theories to spread so rapidly. The aim of this study was to investigate whether retweet fr...

Conspiracy theories have been part of human culture for hundreds of years, if not millennia, and have been the subject of research in academic fields such as Social Psychology, Political Science and Cultural Studies. At present, there has been little research examining conspiracy theories from a Cultural Evolution perspective. This chapter discusse...

Background: Conspiracy theories regarding vaccination programmes, medical side effects, and cover-ups by governments or pharmaceutical companies are prevalent in many countries and have highly detrimental and far-reaching effects on people’s wellbeing. For research and policymaking in public health, it is vital to understand the nature, constructio...

Moral stories are pervasive in human culture, forming the basis of religious texts, folklore, and newspaper articles. We used a linear transmission chain procedure to test three competing hypotheses: (1) that moral content in general is preferentially transmitted between individuals compared to non-moral content; (2) that negativity bias leads spec...

Conspiracy theories about secret agendas behind vaccination programmes, the side effects of medical treatments, and cover-ups by the government or pharmaceutical industry are prevalent in many countries, and can have highly detrimental and far-reaching effects on people’s wellbeing. For, research and policy-making in public health, it is therefore...

Two potential forms of mutation in cultural evolution have been identified: ‘copying error’, where learners make random modifications to a behaviour and ‘guided variation’ where learners makes non-random modifications. While copying error is directly analogous to genetic mutation, guided variation is a specifically cultural process that does not ha...

Rationale: Although vaccines are an invaluable weapon in combatting diseases, they are often surrounded by controversy. Vaccine controversies usually arise with the claims of some parents or doctors who link vaccines to harmful outcomes. These controversies often negatively affect vaccination coverage. Objectives: This experiment simulated a vac...

Recent research into cultural transmission suggests that humans are disposed to learn, remember, and transmit certain types of information more easily than others, and that any information that is passed between people will be subjected to cognitive selective pressures which alter the content and structure so as to make it maximally transmittable....
