Steven Pinker - The Blank Slate

Back in 2003 Steven Pinker demonstrated that human mind at birth is NOT a blank slate and our behavior depends a lot from the gene set that we got.
Pinker also explained Elite/Liberal Arts decline and showed why most of parenting advise (from parenting industrial complex) is plain wrong.

"Identical twins or any siblings separated at birth are no less similar than if they have grown up together. Everything that happens to you in a given home over all these years appears to leave no permanent stamp on your personality or intellect".
