"It takes a factory to build guns!"

No, it doesn't.

And this is why 'social scientists' are so often considered to be bigoted fools.
Perkins published his findings last November in a book called The Welfare Trait (Palgrave Macmillan, £19.99), but you won’t have heard about it or seen it reviewed in any UK newspaper anywhere because his research has been judged to be off limits by the self-appointed guardians of the academic establishment and their outriders in the media. A senior editor of Nature, one of the leading academic journals, refused to consider it for review because she regards scientific research into the personalities of the long-term unemployed as ‘unethical’, and a sociology professor whom the publishers had asked to peer-review the book refused to do so on the grounds that any book linking benefit dependency to personality must be nonsense because personality is a ‘capitalist construct’.
Yeah.  Personality didn't exist until capitalism.  'Social scientist' pronouncement.
