Certain topics, that otherwise might be interesting to discuss, are surrounded by minefields. One such topic is the distribution of intellectual ability within subgroups of the population. In contrast to the minefields that Kolmogorov deliberately avoided, this minefield was not put in place by a repressive government. Nor was it secretly put in place overnight by a fanatic band of social-justice zealots.

My observation, which I will offer without citation, is that this particular minefield was put in place, mine by mine, over a period of decades, through a process of fairly broad societal consensus.

To those who suggest clearing the minefield, thus permitting this topic to be discussed freely in public, I will invoke the principle of Chesterton's fence [1]: Before you talk of removing the mines, you need to show that you understand why the minefield was created in the first place, and you need to explain why now is the time to remove it.
