When tuning a radar system, the operator sets a detection threshold. It a signal does not reach that threshold, no detection event occurs. Not wanting to miss any real returns, an operator might increase the sensitivity (decrease the threshold) so that any real radar returns will exceed the threshold and show up on his screen.

The problem with that is that a lot of noise will also exceed that threshold and show up his screen too.

This is exactly the problem with oversensitive progs, who see normal differences in everyday life and their racism, sexism, and poor-poor-pitiful-me-ism detectors go off.

Black people get arrested more than Whites, so it must be racism, not the fact that Blacks commit more crimes. Black people make less money than Whites, so it must be racism, not the fact that Blacks tend to do less well in school. They see women getting paid less than men, so it must be sexism, not the fact that women are less likely to go into engineering, math, and real sciences, and are less likely to work overtime.

On the other side of the coin, I suspect my bullshit detector is too sensitive, since it seems that everything the progs say sets it off.
