Where she's located doesn't make that much difference because her renown comes from publications in top journals and conference papers. Most academics move to more prestigious universities because they want to, not because they have to. I know internationally famous academics who work at less well known universities. It's also dependent on funding, the ability to attract research monies and teaching loads.The initiative's work is secret so nobody outside the American government and its employees know about it, if Walsh is renowned for psych (though operant conditioning isn't a new discovery) then why is she working at UC Sunnydale instead of a more prestigious college? If she stays at UC Sunnydale because of the initiative then why is she so well known?
Psychology can be as "soft" or as "hard" as you want it to be. In most UK universities it's a BSc because of the need for BPS accreditation but, as far as I'm aware, it's possible to do a BA in Psychology or as part of Combined/Joint Honours degree. It depends on what career path you want to follow. I've yet to see a UCAS application form with "Witch" in the personal statement.
Thanks mate!Sometimes I think academia is like a play pen for people who are a little too eccentric to be let out into the wider world.
