Thanks to everyone who took the time to answer the survey. About 75 individuals did so (I haven't figured it out exactly because not everyone did all four sections). Results were as follows (scale of 1-5):

B1 (Preferred System Complexity): mean score 3.69
B2 (Bidding Aggression): 3.53

I1 (Postmortem Complexity): 3.57
I2 (Bookishness): 3.24

D1 (Carding Complexity): 3.42
D2 (Opening Lead Aggression): 2.98

S1 (Pace): 3.59
S2 (Overall Competitiveness): 3.59

The "typical" survey responder (using the mode of each trait) has a Bridge Personality of: 44 44 33 44. This would correspond to someone who:
--likes a bidding system that is fairly complex
--is relatively aggressive in the auction
--likes to engage in a somewhat detailed postmortem
--often reads bridge books and/or has a fairly extensive collection
--enjoys straightforward carding agreements
--is middle-of-the-road on opening lead
--is a relatively fast player
--is competitive but not cutthroat

I was somewhat surprised by the results for I2; I'm not sure why, but I expected forum users to read more bridge books than is apparently the case (the mean was barely above average). I was also interested to note that there were no "1" or "5" responses on D2 (Opening Lead Aggression); maybe this isn't such a great question if everyone is clumped in the middle.

It might be interesting to see the results of the same questionnaire asking about one's regular partner. I'd be wiling to bet (with your money, of course) that a large majority would rate partner lower on bookishness. I'd guess (not even bet with your money) that the responses would be more extreme (i.e., more 1s and 5s) on many of the questions.

detailing the number of bridge books probably killed some people. I read and reread bridge books all the time, and have subscriptions to two bridge magazines, but I have not acquired 50 real books in my personal library as of yet.
