I read somewhere that kids with IQ 140 waste about half their time in school. Kids with IQ of 170 waste all their time at school. It's no wonder that kids with IQ 145 or greater are mostly home schooled, because there's no real school that can handle them and the issues that come with those kids. Skipping high school definitely sounds like a better path, especially given the social problems with being with kids so much older than you.

  I didn't know but I simply googled it. It's from Leta Hollingworth, a researcher on gifted children from the mid-20th century, her book "Children Above 180 IQ".

What percentage of people have a 145 IQ? That sounds really high.
- darthvoldemort 5y ago
  Every 15 IQ points from 100 is one standard deviation away, where 100 is the average. So 145 is 3 standard deviations away from average or 99.7%.

    I think it's 99.7% within three standard deviations (e.g., in either direction) so presumably half as many are three standard deviations above the mean—99.85% (top 0.15%). Tiny % either way.

  145 is ~ the top tenth of 1 percent. In a large high school there might be one such person.

    I feel the need to be pedantic here, because your post makes a couple simplifications in the same direction that skew the results by roughly an order of magnitude. 145 is the top three tenths of 1 percent, not the top tenth. The average high school size in the US is 854 students [1]. In an average school, you would expect there to be 2.5 students with 145+ IQ. The largest school in each state is about 5-10x the average size school for that state. Let's call a large school 3x average, then. In a large school, you would expect to find 7.5 students with 145+ IQ, or roughly 2 per graduating year. "About 8" and "Maybe 1" are almost an order of magnitude apart. 1: 2011 Dept of Ed statistics https://nces.ed.gov/pubs2011/pesschools09/tables/table_05.asp https://nces.ed.gov/pubs2011/pesschools09/tables/table_05.as...

      Really? I thought that std. dev. was 15, so 145 would be the .9987 quantile, which I abbreviate to about the top .1%. If std. dev. is 16 then it's the top .25%. But we agree on the bottom line: 145 is not rare. You might know someone of this IQ.

    Unless you went to HS with one of biggest gifted programs in a major city, where that level was common. I would say with some certainty they were fine with college aged social activities.
