Testosterone spikes inhibit risk assessment. Testosterone spikes based on social circumstance rather than the time of day. When there are smaller males/females around you can dominate, testosterone spikes. When the other males are bigger, stronger and more aggressive, testosterone doesn’t spike. Making you avoid conflict instead.
A lack of risk assessment, along with increased impulsivity, is a feature. Useful to get males to initiate fighting.
Reducing human behavior to a single hormone is a choice that is not very representative of reality.
Testosterone has complex effects. It is also one of the few hormones that significantly changes in the male brain. Learning to both control and utilise its effects is critical to the proper development of a man.
Testosterone changes your risk assessments, rather than jamming them. Uncontrolled, it can be problematic. It takes practice and training to channel that in productive directions. Without that practice, it’s effects are either bottled up (with a tendency to explode) or lead to fighting, or crude domineering. Neither is healthy.
