Helen Caldicott?
She was on CSPAN Saturday, and it sure sounds like her.
She's a big name on the Left, and got her Psycho Hose Beast license many years ago.
BTW, although she's full of shit about reading IQs, in what way is an IQ of 100, i.e. exactly average, a major handicap? In any case, from my experience at universities, I have seen many people with massive IQs that I wouldn't let within five parsecs of a position of any responsibility. As Stephen King once pointed out in "The Tommyknockers," intelligence and smarts are two different things.
