Richard Lewontin is a Marxist Jew who has dedicated his career to attacking genetics as an explanation for human variation. He co-authored a silly book called Not In Our Genes along with some other nutty Marxist Jew.
According to his fallacy, most genetic variation is within groups and not between groups. 85% is within any given group, and only 15% is between the average of any one group with any other.
Why this is a fallacy can be easily shown. For instance, within Whites, IQ’s in a group of 1000 Whites have IQ’s ranging from 148 to 68 or so. There are 80 points variation within the group.
Now let us look at the average of 1000 Whites versus the average of 1000 Blacks. The 1000 Whites have an average IQ of 103. The 1000 Blacks have an average IQ of 89.8. There are 13.2 points variation between the averages of each group.
According to Lewontin’s Fallacy, the 13.2 point differences between Blacks and Whites is inconsequential to meaningless, since the difference within Whites ranges from geniuses to idiots! Yet that difference has real meaningful consequences at many levels, particularly societal and sociological but also political.
In contrast, the 80 point differences within Whites which Lewontin claims is the real enchilada is just normal variation in any White community, easily handled within the community. The geniuses go on to get advanced degrees, and the idiots get Special Ed, disability checks, easy government subsidized jobs, and state-subsidized group homes to reside in. Everything flows along pretty smoothly.
Pretty dumb analogy huh?
