But it can be.  Find a bunch more characters or make a prediction on a
character distribution.  If they tell the same inferred story or the
prediction works, hypothesis is still good, no problem.

If they don't, amend the hypothesis to accommodate the additional
evidence...  or explain away the evidence to retain a comfortable or
elegant hypothesis...  or go and find some other evidence that  tells
the story you want...

yep, tough call...
