Men in the US increasingly take testosterone supplements. This can lead to impulsive decision making. Hypo-gonadism, causing low T levels, can make a man fatigued, and uninterested in sex, which can be cured with T; but men with ordinary T levels are taking T. What is the effect?
Men and women were given the Cognitive Reflection test, which is a series of maths or logic puzzles with an intuitive, wrong answer and a need to think carefully to get the right answer. Eg, a bat and ball cost $1.10, the bat costs $1 more than the ball. How much does the ball cost? Not 10c.
Men and women given a testosterone boost are less likely to analyse carefully. They care less about what other people would think. They are more likely to think they outperform others. In simulated asset trading, they were more likely to overprice assets, and slower to recognise that prices were falling.
I got all that from the NYT, and recall a factlet from something I read some time- after watching a football match, fans of the winning team had increased T levels, and fans of the losing team had decreased T levels.
More impulsive decision making could be worthwhile in a leader. Where are the mammoths we need to hunt? If our best way of working it out is magic with mammoth bones, it’s better to just guess. We need a decision and it almost does not matter what that decision is. Other people will be grateful for leadership.
In the more complex modern world, good decision making takes account of a wide variety of expertise, and a testosterone-inspired random plumping may be sub-optimal. The problem is, only the women notice.
If high-T males rampage through life damaging things, and women trail in their wake, fixing the mess, the man might never realise he had made any false steps. However the research does not prove that high-T is a bad thing, just that a sudden change in hormone levels can discombobulate a person. I knew that already.
