Take the following as truth: Since The Bell Curve was published, it has become clear that almost everything about it was inexcusably  suspect data, mistakes in statistical procedures that would have flunked a sophomore (Murray--Herrnstein is deceased--clearly does not understand what a correlation coefficient means), deliberate suppression of contrary evidence, you name it.
Then the following statement: "The Bell Curve authors made up some of their conclusions to bolster their hypothesis." is true, false, or inconclusive?
Answer: Inconclusive
