Jezebel is making funny over a Bloomberg report. Bloomberg's not known for Onion-esque pieces. It's based on several studies and a recent book by a neuroscientist.
Coates makes a convincing case that physiology plays a central role in driving markets, one that is generally overlooked. This insight might well form the basis of new investment indexes, even funds, based on widespread real-time monitoring of the hormonal biochemistry of the investing population.
What's more, I don't think it's the least ridiculous or extreme. Doesn't take a neuroscientist to observe that obsessive, aggressive risk-taking is a by-product of testosterone.
I'm a little surprised to see people leaping in and assuming it's a joke.
