Thanks for the recommendation, DNCall.
Have you ever read any of Michael Shermer's work?
He doesn't talk about System 1 & System 2 but he does talk about how our brains are wired for quick pattern recognition. Early humans who ran when they saw stripes in the bushes survived even though 99 times out of 100 there wasn't actually a tiger ready to pounce. Those whose brains weren't as good at pattern recognition got culled by fat & happy tigers.
Here's a link to a brief essay he wrote in Scientific American a while back:
His most recent book is
The Believing Brain
From Ghosts and Gods to Politics and Conspiracies—How We Construct Beliefs and Reinforce Them as Truths
I've got a signed copy that says: "To Open Mind, Yours "in faith", Michael Shermer"
I guess you can tell I'm a fan.
