Men are more likely to make extreme choices and decisions compared to women, a new study has found.
Researchers from the University of Sydney Business School discovered that men were much more likely than women to be at the extreme ends of the behavioural spectrum.
They either acted very selfishly or very altruistically, were very trusting or very distrusting, were very fair or very unfair, were very risky or very risk averse and either very short-term or very long-term focused, and there was no middle ground when making decisions.
They analysed more than 50,000 participants across 97 samples, and found that the extreme choices and decisions of men can be both positive and negative.
And they suggested that policies aimed at reducing extreme behaviours should be more tailored towards men.
Study leader Professor Stefan Volk said that the difference in decision making could be due to male variability, which is an evolutionary theory that suggests men need to stand out to attract more sexual partners.
"Parental investment theory explains that men, in contrast to women, invest less in parenting, are less selective in their partner choice and compete more for sexual partners," he explained.
"This evolutionary theorising suggests that men had to deviate from the average to stand out and be attractive to women to reproduce, while women were able to attract sexual partners without deviating from the average," Volk added.
