Scott Douglas Jacobsen: Close to that mainstream reliability. So, you’re saying less than 10%.
Rick Rosner: It depends on what you’re using IQ for. If you’re using it to see whether or to differentiate a kid at 140 and a kid at 170 who might need super-duper extra help to that point that that kid might need to be home schooled or accelerated to the point that that kid is taking university-level classes at 13 or 14, that’s one thing — differentiating between 140 and 170. If you want differentiate between 168 and 171 because it has turned into some kind of sport, not even official tests can reliably do that, there’s a standard error of measure on IQ tests where you give somebody three different professional level IQ tests and the standard difference between their scores on a couple of tests might be 8 points or more.
You can’t pin it down, even though the tests have scores that are expressible in three digits.
