People lie about their IQ

When I was in college taking a statistics course, the professor began by discussing IQ distributions. He asked people in the class to raise their hand if they had ever told anyone they had an IQ above 145. Many hands went up. He said, "All of you lied." He then asked us to raise our hands if anyone we knew or met had claimed to have an IQ above 145, and many hands went up again. He said, "Guess what...they lied." In order for you to score really high on the IQ test, you'd basically have to ace it. Very few children below the age of 13 would know enough to be able to answer questions as they are adult questions. These are questions an average 18 year old should know. This is not a paper and pencil test either. It is verbally administered in most cases and with a professional scoring you. Many of the tests are timed. When you take online IQ tests, they are not real. They might be sample questions for a real IQ test, but you aren't being timed and your scores are not legitimate. IQ tests are not quick. They take a long time to administer. If you took a 20 question online "IQ test" and scored really high, you probably Googled your answers, and you could do that because it wasn't timed and there was nobody in front of you telling you to put your phone away during the test. In real life, you'd need to answer quick, verbally, and without outside help.
