In summary:BlackVision said:There are a number of factors that causes criminal behavior. Testosterone level would be one of them. Certainly not in all aspects a bad hormone. This magical hormone does many things. It gives you a sex drive, it allows you to build muscle mass, as well as other so called "male" characteristics. One of them is aggressive behavior. Aggressive behavior would often even be positive. It allows you to be more competitive which is great as long as you have it under control. But this aggressive behavior often times turns criminal.
80-90% of homicides are commited by men. It's hard to make a case for environment being the main cause of it. Men are much more aggressive than their female counterparts. That magical male hormone testosterone probably responsible for it.
Now do certain races have a higher median level of testosterone than others? If this is the case, the pattern of higher aggressive behavior should be visible.
race -> testosterone -> aggression -> crime.
Let's examine the last in the chain first.
There are many types of crime; which ones have well-established relationships with aggression? What proportion of all crime do these types comprise?
