Poor research design and data analysis encourage false-positive findings. Such poor methods persist despite perennial calls for improvement, suggesting that they result from something more than just misunderstanding. The persistence of results partly incentives favour them, leading to the natural selection bad science. This dynamic requires no conscious strategizing-no deliberate cheating nor loafing-by scientists, only publication is a principal factor career advancement. Some normative...
Human cooperation is highly unusual. We live in large groups composed mostly of non-relatives. Evolutionists have proposed a number explanations for this pattern, including cultural group selection and extensions more general processes such as reciprocity, kin selection, multi-level acting on genes. Evolutionary are consilient; they affect several different empirical domains, patterns behavior the proximal drivers that behavior. In target article, we sketch evidence from five domains bear...
Abstract Many of the most important properties human groups – including that may give one group an evolutionary advantage over another are properly defined only at level organization. Yet present, work on evolution culture has focused solely transmission individual-level traits. I propose a conceptual extension theory cultural evolution, particularly related to competition between groups. The key concept in this is emergent group-level trait. This type trait characterized by structured...
On October 27th, 2022, Elon Musk purchased Twitter, becoming its new CEO and firing many top executives in the process. listed fewer restrictions on content moderation removal of spam bots among his goals for platform. Given findings prior research hate speech online communities, promise less strict poses concern that will rise Twitter. We examine levels prevalence before after Musk's acquisition find rose dramatically upon purchasing Twitter most types increased, while astroturf decreased.

Many published research results are false, and controversy continues over the roles of replication publication policy in improving reliability research. Addressing these problems is frustrated by lack a formal framework that jointly represents hypothesis formation, replication, bias, variation quality. We develop mathematical model scientific discovery combines all elements. This provides both dynamic as well for reasoning about normative structure science. show may serve ratchet gradually...
Abstract. Turning verbal theories into formal models is an essential business of a mature science. Here I elaborate on taxonomies models, provide ten lessons for translating theory model, and discuss the specific challenges involved in collaborations between modelers non-modelers. It’s start.
<p xmlns="http://www.ncbi.nlm.nih.gov/JATS1">In the wake of replication crisis, there have been calls to increase clarity and precision theory in social sciences. Here, we argue that effects these may be limited due incentives favoring ambiguous theory. Intentionally or not, scientists can exploit theoretical ambiguities make support for a claim appear stronger than it is. Practices include stretching, interpreting an more expansively absorb data outside scope original claim, post-hoc...
We use cultural evolutionary models to examine how individual experiences and culturally-inherited information jointly shape risk attitudes under environmental uncertainty. find that learning processes not only generate plausible variation in attitudes, but also conservative strategies---emphasizing the preservation of generational knowledge---excel high-risk environments, promoting stable wealth accumulation long-term survival limiting asset growth as conditions improve. In contrast,...
It has long been proposed that cooperation should increase in harsh environments, but this claim still lacks theoretical underpinnings. We modeled a scenario which benefiting from altruistic behavior was essential to survival and reproduction. used spatial agent-based model represent mutual enforced by environmental adversity. studied two factors, the cost of unreciprocated living, highlight conflict between short- long-term rewards cooperation. In run, is favored because only groups with...
Humans regularly solve complex problems in cooperative teams. A wide range of mechanisms have been identified that improve the quality solutions achieved by those teams on reaching consensus. We argue many these work via increasing
Recent research has revived Long's "ecology of games" model to analyze how social actors cooperate in the context multiple political and games. However, there is still a paucity theoretical work that considers mechanisms by which large-scale cooperation can be promoted dynamic institutional landscape, join new games leave old ones. This paper develops an agent-based ecology where agents participate public goods In addition contribution decisions, different games, these processes are...
Many social phenomena do not result solely from intentional actions by isolated individuals, but rather emerge as the of repeated interactions among multiple individuals over time. However, such are often poorly captured traditional empirical techniques. Moreover, complex adaptive systems insufficiently described verbal models. In this paper, we discuss how organizational psychologists and group dynamics researchers may benefit adoption formal modeling, particularly agent-based for...
Disease transmission and behaviour change are both fundamentally social phenomena. Behaviour can have profound consequences for disease transmission, epidemic conditions favour the more rapid adoption of behavioural innovations. We analyse a simple model coupled infection in structured population characterised by homophily outgroup aversion. Outgroup aversion slows rate lead to lower rates later-adopting group or even divergence between groups when exceeds positive ingroup influence. When...
SignificanceMuch of online conversation today consists signaling one's political identity. Although many signals are obvious to everyone, others covert, recognizable ingroup while obscured from the outgroup. This type covert identity is critical for collaborations in a diverse society, but measuring has been difficult, slowing down theoretical development. We develop method detect and overt tweets posted before 2020 US presidential election use behavioral experiment test predictions...
When a population exhibits collective cognitive alignment, such that group members tend to perceive, remember, and reproduce information in similar ways, the features of socially transmitted variants (i.e., artifacts, behaviors) may converge over time towards culture-specific equilibria points, often called cultural attractors. Because cognition be plastic, shaped through experience with products others, alignment stable attractors cannot always taken for granted, but little is known about...
