We probably don't disagree too much on the core issue here by the way. Compared to an arbitrary reference class that is somewhat meaningful I tend to be far more likely to accepting of the 'blank slate' capabilities of the brain. The way it just learns how to build models of reality from visual input is amazing. It's particularly fascinating to see areas in the brain that are consistent across (nearly) all people that turn out not to be hardwired after all. Except in as much as they happen to be always connected to the same stuff and usually develop in the same way!
