I am responding based on my experience, first of all premising that anyone who believes Mensa is an association of super-intelligent nerds who act superior is completely off track. I consider myself anything but a Nerd, and those who know me can easily say so; I live a life where I try not to deprive myself of anything, I love art and culture just as much as I love spending time with my girlfriend, going out with friends, talking nonsense, and discussing trivial topics like any other person not enrolled in Mensa.
In my experience, I have been able to evaluate that those who express themselves in this sense towards the association are those who:
1) Do not know the association and speak without knowing what they are saying because they associate: Mensa -> Intelligence -> People who act superior
2) Are afraid of taking the test because they fear they won't be able to pass it
3) Have taken the test but did not pass (the highest percentage in this dispute).
I have been a member of Mensa since 2007 (the year I took the entrance test).
To join Mensa, it is actually necessary to take an IQ (Intelligence Quotient) test. Intelligence is distributed like a Gaussian curve; therefore, in the area of maximum probability (100 at the center of the graph), the largest number of people is concentrated. As you move away from this center, the probability of finding people with a higher or lower IQ decreases progressively. To gain access to Mensa, a member must obtain a score of at least 148 points on the Cattell scale, meaning they fall within the top 2% of the world population. Being a Mensa member thus implies that in a sample of 100 people, 2 will have the intelligence quotient required for entry.
Often, the measurement of the intelligence quotient is mistaken for the measure of an individual's total intelligence. This is TOTALLY FALSE!
The intelligence quotient alone provides some indications as it quantifies the abilities of the individual undergoing the test in a specific area of intelligence, namely logical-spatial intelligence. Total intelligence, however, is determined by a myriad of factors, to name just a few: verbal intelligence, mnemonic intelligence, social intelligence, etc., etc. Therefore, this type of test only identifies the faculty of being able to solve logical problems.
The test consists of 45 questions to be completed in 20 minutes (Raven's Matrices), which are matrices where one cell is missing and must be filled in by choosing from the possible answers.
In the end, the tests will be evaluated by psychologists and the response will arrive within two weeks by mail.
What are the benefits?
I would say first of all having the opportunity to participate in a forum where the most disparate topics are discussed, making new friends, being able to attend very interesting conferences, having support even abroad since Mensa is a worldwide association and, if desired, one can request hospitality abroad from other members, attending dinners, etc., etc.
I have just come from a dinner held last night in a magnificent hotel in Rome. In the morning there was a Brain competition for members and non-members, a conference in the early afternoon, and the dinner. Unfortunately, due to commitments, I could only participate in the dinner.
Here is a small snapshot of my girlfriend next to the Mensa sail...
It is certainly an experience that can also be useful at a curricular level.
I must say that I feel good within the association. At my last concert, even though they were notified at the last minute, 5 members came, of whom I only knew 1 (noting that of my usual friends, only 2 came). It is certainly a place where one can make very stimulating new friendships.
In short, it is not an association where Nerds are enrolled; there are engineers and scientists, but also butchers and workers. The common thread is somewhat the desire to know, to socialize, to exchange opinions, and to rack one's brains: very complex themes such as those related to society, marketing, logic, etc., have often been successfully addressed...
