Patriarchy

Back in the day, (think caveman days,) testosterone provided humans with strong single-minded males good for protection and labor. Force became a way to take control over other humans. Men are bigger.

Since men took power by force they were in place when the human mind began to explore the meaning of life and discovered God. Divine revelation included the idea that men should remain in power and women should be subservient. Imagine that! 

With Divinity and Force on their side men claimed to possess everything. As Economics developed, ownership and 'cash flow' made the trifecta and have been used ever since to retain male dominance.

We cheat ourselves of the wholistic thought processes that testosterone prevents.
