I dunno, Einstein was smart enough to get the fuck out of Europe in the 40's, win a Nobel peace prize and become the most popular scientist of the 20th century,
he probably could have at least figured out some plan of stealing a chicken without lifting a finger.
Haha, my thoughts exactly.
I don't think IQ tests are 100% accurate, but they are a pretty good assessment of a person's ability to attain knowledge
(not the actual amount of knowledge that they have). This is measured by the person's capacity to reason, to plan, to solve problems, to think abstractly, to comprehend ideas, to use language, and to learn. This is why your IQ score remains basically unchanged from childhood to old age. It doesn't matter how many books you've read, how many degrees you have, or what you've studied. I took an IQ test in the third grade and scored 134. I haven't taken one since, so I don't know if it's the same, but I would assume so.
So I wouldn't say that Einstein would be considered a "dumb shit" in a raw nomadic world of hunter-gatherers. In fact, if he has such a high IQ, then he would be able to adapt more quickly and successfully than most people. If Einstein were born in the Stone Age, he wouldn't have been a physicist, but I bet you he would have been one smart caveman. He probably would have been the one who discovered agriculture, astronomy, or metal tools. And I'm pretty sure he would have no problem stealing a chicken. I don't know what makes you think he wouldn't be capable of that.
There probably is a small Western bias, but it would be extremely difficult to have one universal test for the whole world. I know there are several different kinds of IQ tests, but I'm not sure if there is an "Eastern" version or something similar.
