SUMMARY

The discussion centers on the limitations of IQ as a measure of intelligence, highlighting that it is a relative metric based on percentiles rather than an absolute measure of cognitive ability. The example of Albert Einstein, with an estimated IQ of 160, illustrates that such scores do not accurately reflect the vast differences in cognitive capabilities, such as computational speed and creativity, between individuals. The conversation emphasizes that IQ underrepresents those at the top of the intelligence spectrum and suggests exploring broader metrics in psychometrics to better understand cognitive abilities.

PREREQUISITES
  • Understanding of IQ testing and its historical context
  • Familiarity with psychometrics and cognitive ability assessments
  • Knowledge of cognitive functions such as computational speed and creativity
  • Awareness of the implications of using IQ in educational and psychological settings
NEXT STEPS
  • Research psychometric tests beyond IQ, such as emotional intelligence assessments
  • Explore the relationship between cognitive abilities and specific tasks in neuroscience
  • Investigate the historical development of IQ tests and their intended purposes
  • Examine case studies of individuals with exceptional cognitive abilities, such as those with eidetic memory
USEFUL FOR

Psychologists, educators, and researchers interested in cognitive assessment, as well as individuals seeking to understand the complexities of intelligence beyond traditional IQ metrics.

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.
