"Modern IQ tests are made up of about a dozen subtests which make insignificant 'impurities,' specific aptitudes or bias from social and educative factors."

I'm not at all sure what that means. Perhaps you can explain it in plain English.

When I ask a child to identify a picture of an electrical outlet and he says its a "plug-in", the answer is incorrect. I am not allowed to mediate. I only administer the test and score the results.

Thats how testing is conducted. Regardless of how 'insignificant' the impurities might be, the final score is always effected. I'd have to see these so-called, modern tests to determine how unbiased they are. I am certainly not going to take your word or Dr. Watson's word for it. His word is worth nothing.
