Since this is an informed discussion, I get uneasy when practices are
promoted based upon superstition rather than evidence.

Question: is there any supporting evidence that dumping the bees on the
ground away from the hive prevents the laying worker(s) from returning?  Or
is this simply a commonly-practiced superstition?

Does anyone know whether a simple controlled trial has ever been performed
to see whether it makes a bit of difference to go through the motions?  It
would be very easy to perform such a trial by creating a group of laying
worker colonies, and then attempting to requeen them all with a nuc, but
only shaking the bees in half of them.
