The study of moral judgements often centres on moral dilemmas in which options consistent with deontological perspectives (that is, emphasizing rules, individual rights and duties) are in conflict with options consistent with utilitarian judgements (that is, following the greater good based on consequences). Greene et al. (2009) showed that psychol...

Background: Public opinion on who performs more beauty-enhancing behaviors (men or women) seems unanimous. Women are often depicted as primarily interested in how they look, opposed to men, who are presumably less focused on their appearance. However, previous studies might have overlooked how masculinity relates to self-modification among men. M...
Article
Disgust sensitivity differs among men and women, and this phenomenon has been observed across numerous cultures. It remains unknown why such sex differences occur, but one of the reasons may relate to differences in self‐presentation. We tested that hypothesis in an experiment comprising 299 participants (49% women) randomly allocated into three gr...

It has been hypothesized that an increase in literacy within a society is associated with more negative perceptions of aging and older adults. The present study empirically tested this premise among the Dani in West Papua. Sixty-one Dani participants were asked to nominate two individuals within each of the following categories: (1) most respected,...

Although the susceptibility to reasoning biases is often assumed to be a stable trait, the temporal stability of people’s performance on popular heuristics-and-biases tasks has been rarely directly tested. The present study addressed this issue and examined a potential determinant for answer change. Participants solved the same set of “bias” tasks...

According to a view widely held in the media and in public discourse more generally, online hating is a social problem on a global scale. However, thus far there has been little scientific literature on the subject, and, to our best knowledge, there is even no established scholarly definition of online hating and online haters in the first place. T...

The beauty of science lies within its core assumption that it seeks to identify the truth, and as such, the truth stands alone and does not depend on the person who proclaims it. However, people's proclivity to succumb to various stereotypes is well known, and the scientific world may not be exceptionally immune to the tendency to judge a book by i...

The male beard is one of the most visually salient and sexually dimorphic traits and a hypothesized potential marker of other traits, such as dominance, masculinity, social status, and self-confidence. However, as men can easily alter their facial hair, beards may provide unreliable information about the beard owner’s characteristics. Here, we exam...

To tackle the spread of COVID‐19, governments worldwide have implemented restrictive public health behavioural measures. Whether and when these measures lead to positive or negative psychological outcomes is still debated. In this study, drawing on a large sample of individuals (Ntotal = 89,798) from 45 nations, we investigated whether the stringen...

Research has demonstrated that increases in testosterone (T) concentration can affect the expression of behaviours and preferences that are typical of high mating effort. However, little research has considered whether such T increases affect mating strategy more generally and whether this is achievable using a physical intervention. In this pilot...

Measuring food wasting behaviour at the consumer level is challenging. Most existing methods focus on food wasting at the household level, which in turn limits the possibility to study the situational and individual factors shaping food wasting behaviour in a single person. To fill this gap, we conducted a series of pre-registered studies in which...

How can we maximize what is learned from a replication study? In the creative destruction approach to replication, the original hypothesis is compared not only to the null hypothesis, but also to predictions derived from multiple alternative theoretical accounts of the phenomenon. To this end, new populations and measures are included in the design...

Stress and threats have been shown to influence our cognition and performance. In a preregistered online experiment (N = 446), we examined whether thinking about the ongoing covid-19 pandemic influences creative (insight problem solving) and analytic thinking. We found no support for our a-priori hypothesized effect (decrease in insight problem sol...

The digit ratio (2D:4D) is said to be a potential marker of exposure to prenatal sex steroids. Some studies suggest that the 2D:4D is also linked with the testosterone response to challenging situations due to organizational effect of prenatal hormonal milieu on adult endocrine functioning. However, up to date, there were only four studies (conduct...

The Trivers-Willard Hypothesis (TWH), frequently investigated by evolutionary psychologists, states that human beings may have evolved to produce a greater number of sons when having a high status, and a greater number of daughters when having a low status. To test this hypothesis, we examined the sex of children of Polish high status: kings, dukes...
