This is ONE OF 2 responses to Vol 16 Larry 1 ("Qualitative analysis")...
Larry brought up an excellent point. It would be difficult for John to bring sex into the conversation in many voice cards.
With this in mind, I analyzed his contributions in the latest volume (16), throwing out cards where a mention of sex would be difficult or awkward.
The results: John scored a comfortable 66% on the S.F.I.
Admittedly, my classification scheme was rather subjective.
