>I suspect that there a quite a few things we do that seem to be a good
idea, but of which there is no decent evidence as to their benefit.

Unless one runs a control group, how would one notice whether there was an
"obvious" detriment?  I can think of plenty of  beekeeping practices that
are of detriment to the bees, yet commonly practiced.
