There are enough people, mostly on the left wing, who refuse to accept that we are born with different brains, that author Steven Pinker felt he had to write a book called The Blank Slate to refute this idea. In a famous example of blank slate thinking, a sex change clinic for children with ambiguous genitals here in Norway would randomly assign sexes to children, believing them to adapt to any sex assigned to them, since gender roles were obviously a construct of society, and male and female brains were of course identical at birth. It turned out to be disasterous for the children in question, and they changed their practices to include a gender identity test.

The way the Scandinavian system is designed is strongly biased toward this kind of thinking.
