A high-IQ society is a club where only people who are very smart can join. To join, you have to take a special test called an IQ test. IQ stands for intelligence quotient, which is a way to measure how smart a person is.
Think of it like a game where you have to solve puzzles and answer questions. The more puzzles you solve and the more questions you answer correctly, the higher your IQ score will be. If your score is really high, like 130 or more, you might be invited to join a high-IQ society.
These societies are like clubs or groups where people who are really smart can meet and talk to each other. They might have parties or events where they do things like play games or learn new things. They might also have special programs or scholarships for members who are still in school.
Being in a high-IQ society doesn't mean you're better than other people or that you should act like a know-it-all. It just means that you're part of a group of people who are really good at solving puzzles and figuring out tricky problems.
