I didn't vote.
The phrasing of person A is poor, but I believe what they intend to say say is that they're empiricist.
What they're actually saying is that they come form a conclusion, then set out to support it, but then listen to the data they find.
The first interpretation is more charitable. The second is more likely to be what is happening (because human), whether that's what they meant to say or not, it's much, much easier to start off with a conclusion and then find supporting evidence. I'd love to see some stats on just how many google search terms are phrased in such a way to disprove a preconception, rather than support it.
