I'd be interested to see some data on what the real ratio is.
I suspect that 1 in 5 might actually be high, which IMHO is sad -- not because I think less of those without any kind of Lisp experience, but because I think they are seriously missing out.
For any CS folks (or just developers in general) who have thought about learning a Lisp of some sort, but for some reason have never gotten it done, I would encourage you to do so -- it really is worth the effort.
I know; if any random sample of five CS people could be expected to have 0.9 to 1.1 Lispers in it with a 19/20 confidence, that would be a different world, ha!
