This is not a group of people getting together because they share an interest, it's a group of people who seek to seperate themselves from the rest of the population on the basis of a near-meaningless measure of intelligence.
I have talked to a few people from my local chapter of mensa and most of them joined as a way to meet people, they joined so that they would have an easier way to find people to socialize with. They definitely aren't looking to "seperate themselves from the rest of the population," in fact, the exact opposite is true.
Mensa states it's goals as the fostering of human intelligence, encouraging research, and to provide intellectual opportunities for its members. Which of those goals requires an IQ above 140 to accomplish? Mensa is a joke.
Just because none of these goals REQUIRES an IQ in the 98th percentile doesn't mean that a group composed of these people cannot attempt to accomplish these goals. That is not the only goal of mensa, here is a quote from the website of my local chapter. " But we are more than just a social organization. Although one of Mensa's purposes, as stated in our constitution, is "to promote stimulating intellectual and social opportunities for its members
," another is to "identify and foster human intelligence for the benefit of humanity." With this in mind, local Mensans also contribute energy, knowledge and money to educational, adult literacy, and similar programs in our community. To support such activities, and to keep our group going, we also do some fundraising - another good excuse for socializing. You may find us helping at the Scottish-Irish Festival or running an occasional garage sale." To me that doesn't sound like a group of people seeking to seperate themselves from the rest of society.
