What percentage of the population has an IQ of 150 or better?

to answer your first question, go to

www.assessmentpsychology.com and click on IQ and find the answer in the chart.

150 and better is about the top .05 percent.

And, sorry, if you're taking online tests, they aren't very accurate. I got everywhere from 143 to 155 when I was taking all sorts of online IQ tests a few years ago, but I know better than to take them seriously.

You should have yourself professionally tested! I'm sure you're in the top 5%, but online scores or any unprofessional practice IQ tests need to be taken with a grain of salt.

Good luck!

Go to an educational psychologist and take one of the main psychometric IQ tests if you want to confirm your results from online IQ tests. The psychologist will also give you an analysis.

I take online IQ tests for fun, and I sometimes score labout the same, sometimes lower and sometimes higher than on the WAIS IQ test given to me by a psychologist, so they are not necessarily bad or inaccurate- but do them just for fun.

i think the majority doesn't care about iq tests...it's all about the benjamins

Mine is 163, but all I care about is death.... so I only memorise morbid statistics.
