Default Gliders and Transponders......again.

I'll bet, on average, that people that have a PCAS look out MORE than
those that don't have one. The reason is feedback. When you don't have
a PCAS you scan, but mostly you don't find anything. Lacking positive
feedback (a reward), your scan degrades. When a PCAS alerts during
your scan, you naturally increase your visual lookout until you find
the target. This is reward based training, and over time you learn to
look harder and better.
