IQ：我参加了3个IQ测试，为何结果差异能非常之大

I took 3 IQ Tests in my life (108, 132 and 150). How can the results be so widely different?When I was a small child, I supposedly got the lowest score the tester had ever seen on one type of IQ test, followed by the highest score they had ever seen on a different type. Granted, mine was an extreme case - I had both obvious gifts and obvious deficits. But most people aren't equally good at everything.Also, you're not going to perform the same on any given test. Maybe your sleep was off, or you just got upsetting news. Or maybe you happened to know the trick for something and solved it quickly. IQ is a meaningful predictor at the population level, but it's a crude estimate (at best) for any given individual.
