I admit the system is subjective. This is a gray area: nomina dubia
are in the eye of the beholder. But I think this is OK. On that
point, David M. made this statement:

I think this is too harsh when applied to paleontology and biology,
because frequently we deal in probabilities, rather than absolute
certainties. That's why statistics are so important. For example,
one phylogeny does not *disprove* another phylogeny; one phylogeny is
only deemed more probable based on a set of pre-determined
assumptions (such as parsimony).
