Snake oil. I would say rational. In order for your theory to work, then all other races would have to stop improving or stand still. In what world will that occur. You and others like you who think that this will occur are insane and irrational. Also, why is it that when you take into account the improvement of other minorities, outside of African Americans, the data show that these groups are improving or ahead of whites, especially when looking Asians and Jews? Again, another data point that shows you were your argument falls flat. However, in order for your to acknowledge this point, you will have to answer the question what is causing blacks to not improve? I fear you will not like the answer you receive after being confronted with the problem as opposed to the symptoms. Free your mind.
