I enjoyed Mensa. I went to weekends away, and evenings in the pub. I met some nice people, and some crushing bores. I took the test initially to try and boost my social life. I do not think I had more intellectual discussions than I do with work colleagues.

Sir Clive Sinclair for a time hosted weekends in moderate hotels, with dinner parties. So I have enjoyed a couple of long general discussions in a group of about a dozen including him and Madsen Pirie of the Adam Smith Institute, and he is still one of my best name-drops.

When I foolishly disclosed to an employer that I was in Mensa, every time after when I made a mistake he would say, "Mensa strikes again!", mockingly. I think being in Mensa does not give a useful signal.

I have kind of lost interest. I have other social groups to join with. The magazine in Britain is not interesting.
