After edit: I would be very glad to see citations to research sources that back up any of the statements made in your comment. I would want to look especially at methodological issues<p><a href="http://norvig.com/experiment-design.html" rel="nofollow">http://norvig.com/experiment-design.html</a><p>if a study claims that something can't be done (rather than claiming that something hasn't been done).<p>After further edit: There is recent research showing that learning can actually change brain neural connections,<p><a href="http://www.post-gazette.com/pg/09344/1019898-115.stm" rel="nofollow">http://www.post-gazette.com/pg/09344/1019898-115.stm</a><p>so I think this year the burden of proof is on the people who claim lack of malleability, since malleability of human brain function is a replicated research result.
