Dog Breed Doesn't Affect Behavior, According to New Genetic Research

This is true, but only in the stupidest sense. If you include enough traits that most dogs have, breed will appear non-predictive. But, breeds aren't supposed to predict those traits; they're supposed to predict once less evenly distributed.

It's like saying "color doesn't predict most attributes of a can of paint" because the underlying formulation is mostly consistent between colors.
