"What kind of people are Members of Mensa?
There is simply no one prevailing characteristic of Mensa members other than high IQ. There are Mensans for whom Mensa provides a sense of family, and others for whom it is a casual social activity. There have been many marriages made in Mensa, but for many people, it is simply a stimulating opportunity for the mind. Most Mensans have a good sense of humor, and they like to talk. And, usually, they have a lot to say.
Mensans range in age from 4 to 94, but most are between 20 and 60. In education they range from preschoolers to high school dropouts to people with multiple doctorates. There are Mensans on welfare and Mensans who are millionaires. As far as occupations, the range is staggering. Mensa has professors and truck drivers, scientists and firefighters, computer programmers and farmers, artists, military people, musicians, laborers, police officers, glassblowers--the diverse list goes on and on. There are famous Mensans and prize-winning Mensans, but there are many whose names you wouldn't know."
IQ is the measure of intellegence not the depth of the well of ones knowledge (or their language skills) . Intellegence is the practical application of knowledge. The person with the higher IQ is more likely to be able to "think on their feet". 2% of the population qualifies for membership to Mensa with 6,437 members, Arboristsite has 128 potential mensans.
