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...

Why not set up some public-service robot traders to counteract the behavior of traders when it snowballs into extreme moves? I show a blueprint of how this can be accomplished taking advantage of the theory of complex systems.

This essay asserts that the mutual gains accruing from the exchange of goods between siblings can moderate the famous parent-offspring conflict, an issue of interest in evolutionary biology. The rationale combines basic concepts of economics and behavioral genetics, and fills in the gaps of...

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 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...

Group thinking is the notion that animals do those things that maximize the chance of survival of their species. It is wrong because natural selection does not favor what is good for the group or the species; it favors what is good for the individual. Here, I show through examples how group...

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...

By combining basic concepts from economics and genetic economics, I elaborate a rationale for the mutual gains from the exchange of goods between siblings to moderate the famous parent-offspring conflict, an issue of interest for evolutionary psychology. The rationale also fills in the gaps of...

A recent neurobiology study showed that monkeys systematically prefer risky targets in a visual gambling task. We set a similar experiment with preschool children to assess their attitudes toward risk and found the children, like the monkeys, to be risk seeking. This suggests that adult humans...
