ok. i'll take your statistical analysis as authoritative and toddle off then. You're taking an introductory psychology course, so of course I should defer to your judgement on this.
Secondly, I don't buy it that the TSA is effectively an IQ test. You're full of shit on most things, so you probably are on this too. Also, you have yet to raise any substantive objections to the other subject specific tests. If private schools put as much effort into their pupils' applications as you suggest, they must surely be able to fool admissions tutors who, after all, have better things to do than carefully read applications.
Lastly, you've got me there. I admit it: black people are genetically stupider than us white folk. James Watson told me so.
