I’ve been a member for 20-ish years, and was chapter president in a prior locale. What follows is more a collection of factoids than a coherent essay.
It’s an odd group. You may find some fun folks or you may find it like tbdi found it. One of our local members here jokes that Mensa is a support group for people who score on the extreme fringe of a particular psychological test.
I will say as a general rule the folks are slight misfits, and comfortable with that. They are understanding that you too are probably a misfit and they are greatly relieved to have found a community where they’re not either uninterested, or unwelcome. Some folks are quite mainstream, just tolerant, while there are might also be a few real out-there’s who’re so weird they’re barely tolerated by the group.
The membership requirements are an IQ in the top 2%, so the potential field of membership nationwide is on the order of 6 million. That the actual national membership is just about 60 thousand says the group does not appeal to everyone who’s smart enough to join. Of course, 100% of America is eligible to join the NRA or WWF or SPCA or … & damn few do, so that’s not much of an indictment of Mensa.
Each local group is different. Some groups have a lot of pretty solid ordinary citizens, others are mostly a gathering of flakes & nuts. Economically, most are middle class. Most are college-educated but there are many who had the brains but never had the chance. Those folks make especially avid Mensans since their fellow truck drivers or warehousemen aren’t great conversationalists.
The national membership is about 50/50 male/female.
The average age is around 45 and under-25s are pretty rare.
US National Mensa also has a chapter expecially for the goegraphically remote. That has a more rural flavor and you may find that more interesting / relevant than the group in CSprings. They communicate via email, messageboard, etc.
Only 10-15% of the membership actively participate in the local chapter events (happy hours, dinner, picnics, game nights, etc). The rest pay their dues, get the magazine & do gosh knows what.
While the mensa website http://www.us.mensa.org talks about higher purposes, at the local level Mensa is really just a social club, a chance to get together & hoist a beer with convivial folks who share some of your quirks.
Conversation can be real mundane, or kinda abstruse, or both at once. Around a table you often get 6 people having 3 conversations simultaneously but all 6 people are in all 3 conversations. Topics are not that different from what other people that age talk about, but somehow the tone is different.
As Licentious Ectomorph says, there is definitely a crackpot fringe that uses Mensa publications as a soapbox to spout their silly ideas. Heck, there are even fools who write in to say they believe in god. They’re much more prevalent in print (or on the messageboards) than they are in real life.
Now for some advice:
Go vist the group in CSprings before you spend any money. They’d be glad to have you come to one of their events. Heck, you can attend as often as you like for months before anybody pressures you to actually join.
This is their web site http://www.plainsandpeaks.us.mensa.org/ . It has contact info for the local chapter officers, their schedule of activities, and an archive of the monthly local newletters. Read it to get a flavor of what they’re like then go try it out.
You’ll either like it (or not) and the only way to know is to give it a whirl.
