    Iq
In summary, the conversation discusses the limitations of using IQ as a measure of intelligence, pointing out that it is a relative measure and does not accurately represent the true cognitive abilities of individuals. The participants also mention alternative metrics and suggest that IQ should only be used in specific contexts, such as identifying students in need of special help.

What is interesting is that IQ is based on percentile. Isn't this number a misleading in an intuitive sense?

For example, consider Einstein. It is estimated that his IQ is somewhere around 160. Obviously this is well within the top one percent.

But the number doesn't really say how many times more intelligent( computational speed, creativity, being analytic etc) he is compared to someone of an IQ of 100.

And I think a misconception is that the score implies 60% greater.

Consider the effects of the tasks. In a few brief moments, he is able to derive things that would normally take an expert entire lifetimes to do. From this viewpoint, the computational/creative power of this brain is obviously far more than 60% greater than average. I would argue that it is so much greater that it is in a sense transcendent.

IQ is a relative measure. I suspect that it far under represents those at the top.

I'm just using Einstein as an example. But there are some tasks that those with higher IQ can do many times faster than one that is lower. So this is a general observation.

Another example are people with eidetic memory. They can perhaps memorize up to hundreds of times faster than a regular human. So that area of the brain is obvious going to be computationally greater by a wide margin.

So then what encapsulates brain power?

There are a lot of different metrics that measure different aspects of peoples' cognitive abilities. You might want to start with a search for psychometrics.

Unless you have a specific reason for wanting to quantify something, i.e. you're studying how exposure to a certain drug changes a person's cognitive function, it's best not to worry too much about such things. Too many people get too worked up over what, when applied incorrectly or out of proper context, essentially amounts to arbitrary numbers.

IQ is of value to specially trained psychologists looking for problems with patients and in schools for help in school placement for mentally disabled students. It was originally developed to identify students that needed special help. Any other use is questionable. It was not developed to see how smart someone was. Thread closed.

1. Is IQ the only measure of intelligence?

No, IQ is not the only measure of intelligence. There are multiple types of intelligence, including emotional intelligence, social intelligence, and creative intelligence. IQ only measures a small portion of overall intelligence.

2. Can IQ scores change over time?

Yes, IQ scores can change over time. Factors such as education, life experiences, and even physical health can impact IQ scores. Additionally, IQ tests are not always reliable and can produce different results each time they are taken.

3. Are IQ tests biased?

Yes, IQ tests can be biased. They often reflect the cultural and societal norms of the population for which they were created. This means that individuals from different cultures or backgrounds may not perform as well on the test, even if they possess the same level of intelligence.

4. Can a high IQ guarantee success?

No, a high IQ does not guarantee success. Intelligence is just one factor among many that can contribute to success. Other factors such as motivation, hard work, and opportunity also play a significant role in determining one's success.

5. Should IQ be used as the sole measure of intelligence?

No, IQ should not be used as the sole measure of intelligence. As mentioned earlier, there are multiple types of intelligence, and using only one measure may not accurately reflect an individual's overall intelligence. It is important to consider other factors and use a variety of measures to get a more comprehensive understanding of intelligence.
