That's a strawman argument you know. And I gave the same reply to a leftist when he replied with that kind of wording - " oh that's a right wing historian". That was just one of the first source and in the end it only says :
Some criticism may be politically motivated but I find his point about it not being an academic book but self publishing theory pretty valid. This book is not an academic work and yet being used as such.
Both camps say they debunked others theory. So, have you actually checked out the details of the IQ samples and tried to determine validity of the assumptions made in this theory?
I didnt reduce all his criticisms to being politically motivated, I acknowledged that some of his criticisms were apolitical (miscalculations/incorrect sources), and as far as too agree with the point about I.Q. not being an end all be all determinant of life sucess and that socioeconomic factors were ignored in the study. I only prefaced my response about Lemann's political bias because he shows it in his tone throughout his article in how he approaches TBC.
Now, I'd like to see the reassessment of Murrays data that Lemann referenced in his article, but it's not only unpublished, it's not sourced anywhere on the page outside of mentioning the participating parties. I tried googling for it, but only came up the link to Lemann's article, so I can't really weighout the scales between the two to sets of data to see if either one debunks the other. Instead, I'll work from common knowledge.
The general consensus on what percentage of I.Q. his attributable to genetics is around 50%. Taking all relevant figures into consideration, Murray claims that the percentage is no lower than 40% and no higher than 80% (which leaves a large margin of error) which can be averaged out to 60%, and Lemann's uncited, published research team found that the percentage was 30% to 50% hereditary. All three seem to overlap around the 50% mark with only Murrays' highball of 80% and Lemann's lowball of 30% being "outliers". I personally believe don't believe that the 80% mark doesn't fall too far out beyond the realm of possibility, but you may disagree. I also believe that if Lemann wants to criticize Murray's figures for having to wide of a margin of error, he has every reason to do so, but I don't believe Murray's figures is enough to discredit TBC as having miscalculations.
Well when your sources don't even agree with you, why would I believe you? Maybe you should go back and re-read them.
Im literally using information from thoses sources in literally all my arguments in every single post in this thread. You're either being disingenous or your reading and comprehension skills aren't up to scale. If you find that my sources are in complete contradiction to my arguments, ignore my comments as lunacy and keep believing what you believe. I don't have time for games.
