The task that you are engaging is quite difficult, as I am sure you
realize. If participants are to hold confidence in any collective
understanding or decision two things must be assured: 1) all of the
relevant ideas have been included, and 2) all of the relevant relationships
among ideas have been considered. If either of these conditions are not
met, participants will hold weakly to any recommended outcomes because they will
sense -- if not explicitly recognize -- that the conclusions can be compromised
by not knowing what we do not know. This isn't an unusual predicament, but
it seemed worth adding in the context of the effort.
