I was on the street in Cambridge, Massachusetts, one Saturday night in 1970. A hawker passing out half-sheet flyers with a mimeoed paragraph put one in my hand."FREE SCIENTOLOGY LECTURE" time, address, room number--ah ha, within fifteen minutes, right here, upstairs, down the hall.
A room full of folding chairs with a brother in a plaid used-car-salesman jacket at the chalk board. Very jive, very Psych 101.
I asked a few questions; got a few glib brush-offs.
Finally the E-meter: two washed-out soup cans sans labels, wired to the mystery meter read by used-car-salesman brother in his wild and crazy jacket.
Questions and response. Stupid questions--
--and, wonder of wonders, Jive Jacket Man told me the dire news--
--I had "negative concepts" and would need work.
I handed him back his cans.
