It's funny when a science experiment confirms what hippies have been saying for decades, hippies like Steve Jobs included:

"I wish him the best, I really do. I just think he and Microsoft are a bit narrow. He’d be a broader guy if he had dropped acid once or gone off to an ashram when he was younger."

Broader thinking is the exact effect the study identified.

Wonder how long it'll be before this headline makes it into anti-drug programs as "DRUGS WILL CHANGE YOUR PERSONALITY FOREVER", without any mention that the study findings were that the changes were positive.
