Testosterone levels are linked to honesty
Testosterone can have a significant impact with regard to social behaviour. This is the suggestion of new research published in the Public Library of Science's journal PLoS ONE, which found an association between the sex hormone and honesty.
Investigators working alongside Dr Armin Falk, an Economist from the University of Bonn, discovered that in play scenarios, people who were given testosterone lied less frequently than those who only received a placebo.
Professor Bernd Weber, a Neuroscientist from the learning institute's Center for Economics and Neuroscience, noted: "Testosterone has always been said to promote aggressive and risky behaviour and posturing."
However, it has been suggested that testosterone also fosters social behaviour, with lead author of the study Dr Matthias Wibral explaining the hormone does not only influence a person's actions, but these behaviours also affect their hormone levels.
The researchers also indicated the hormone raises pride and the wish to portray a positive self-image.
Chartered Psychologist Professor Daryl O'Connor from the University of Leeds comments:
"These findings are very interesting and suggest that the effects of testosterone are not restricted to reproductive and aggressive aspects of human behaviour. Importantly, the results should reinforce the notion that testosterone frequently plays an adaptive as well as maladaptive function in terms of social behaviour. However, this may not be the case at higher, supraphysiological levels (or doses) of the hormone."
