While I agree that this guy needs to hand in his "Scientist" card this is an individual who no more reflects on his field than any other individual does on theirs.

There was a notable climate scientist whose response to people asking for his data was literally "no, you'll just try to use it to prove me wrong".

Edit: exact quote:"Even if WMO agrees, I will still not pass on the data. We have 25 or so years invested in the work. Why should I make the data available to you, when your aim is to try and find something wrong with it." http://www.theregister.co.uk/2009/08/13/cru_missing/

That doesn't make all climate scientists kooks any more than this guy makes all social scientists kooks.

There will always be people who manage to get research grants despite not really getting the whole point of science.

People who view being "right" as more important than having the correct answer.

People who respond to having authority by deciding that questioning authority, questioning them, is wrong and bad.
