The Claim
Testosterone administration has no differential effect on economic preferences based on baseline testosterone levels, cortisol levels, or personality traits including dominance or impulsivity, as no statistically significant interactions were observed in a sample of 1,000 men across preregistered and exploratory analyses.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In a study of 1,000 men, giving testosterone did not change economic decision-making differently depending on a person's starting hormone levels or personality traits like dominance or impulsivity.
See the scientific wording
The effect of testosterone on economic preferences does not differ based on baseline testosterone levels, cortisol levels, or personality traits such as dominance or impulsivity, as no statistically significant interactions were found in a sample of 1,000 men across multiple preregistered and exploratory analyses.
Testosterone binds to receptors in brain regions that control risk-taking and fairness decisions, changing how those areas communicate. This change happens the same way in everyone, no matter how much testosterone they had before or how dominant or impulsive they are.
What the research says
1 studyScientists gave men a dose of testosterone and saw no change in how they made economic choices, no matter how much testosterone they had naturally or how dominant or impulsive they were. So, testosterone doesn’t affect decisions differently based on who you are.
