This goes to show you how we can end up in trouble so often. Blame it on the disease, because it's most likely to be true. But if people start predicting what I'm going to do BEFORE I do it, I'm doomed!

quoting from linked article above:
It follows previous research by the University College London team, which, using imaging techniques, detected a signal in the brain linked to how much someone enjoyed an experience. They found that signal could in turn predict the choices a person made.
With the suspicion that the signal was dopamine, the researchers set up a study to test how people make complex decisions when their dopamine system has been tampered with.

Seriously, they tested 61 people, using sugar pills and having participants "imagine" where they wanted to go for a holiday. I don't see much in the way of test relibility there, do you?

I think they need to research how our personalities are altered due to dopamine. Now there's a real needed study.
