We examine whether investing experience can dampen the disposition effect, that is, the fact that investors seem to hold on to their losing stocks to a greater extent than they hold on to their winning stocks. To do so, we devise a computer program that simulates the stock market. We use the...

We assess the psychophysiological characteristics underlying the disposition effect and find that subjects showing greater disposition effect are those who sweat more and present lower body temperature and heart rate.

We replicate the Stanford marshmallow experiment with a sample of 141 preschoolers and find a correlation between lack of self-control and 2D:4D digit ratio. Children with low 2D:4D digit ratio are less likely to delay gratification. Low 2D:4D digit ratio may indicate high fetal testosterone. If...

We show that preschoolers exhibit the endowment effect as evidenced by experiments where children generally chose to keep their own toys rather than trading them for similar ones. Furthermore, we relate the emergence of this effect to children’s innate psychobiological traits—emotional...

A recent population-wide study for Germany, where credit lines on current accounts are available to 80 percent of the population, finds that overdraft debt is more likely for people who give intuitive but incorrect answers on a cognitive reflection test. This suggests those consumers in debt...

We experimentally assess the disposition effect and return performance, using electroencephalogram to measure the brain activity of the participants. The design of the experiment follows a previous protocol (Frydman et al., 2014). Our sample was made up of 12 undergraduates (all male, age range...

Group thinking is the notion that natural selection favors what is good for the group or the species, not for the individual. Most mainstream evolutionary biology rejects this idea and natural selection is viewed as working on the individual’s genes to promote their own survival and...
