I was thinking, for example, of amatory selectiveness on the part of
teenage girls. If mates are chosen indiscriminately and there is no
chance of getting a supportive one, the proper strategy is to mate early
and often. That's the current positive feedback, in the wrong
direction, and that
*does* create social instability. If mates are being chosen for their
supportiveness, more selectiveness is appropos. The best part of this
positive feedback is that it operates on the derivative; if we can get
the process to reverse itself only a little, it's self-sustaining.
