Character Polarity (from Molecular taxonomy: on way out?)

If you believe that then you have nothing to worry about. Few people
know are have analyzed fully everything they have a strong opinion about
and I would predict that this applies to most if not all participants in
TAXACOM discussions. It's a well known fact that scientists cover up
their weaknesses of knowledge and understanding. It would probably be
career suicide to do otherwise.

I've seen the lack of technique analysis in biogeographic discussions on
TAXACOM where people have strong views on panbiogeography and on
dispersal without having analyzed the technique. However, I would not
simply say that they have disqualified all their statements.
