Hi all! Laymen here interested in quantative psychology. I recently pondered up a scenario that I've been itching to have answered.

Say two scientists look at the same study and agree on its quality. One takes the findings at face value. The other says: "this other phenomenon Y also scored positive the same metric as the this study, X, but in addition has Z property, so therefore X probably has property Z too."

Is that second move considered evidence for the claim about the other phenomenon? Or is it just a hypothesis that now needs to be tested directly? My intuition says the latter.

Thanks in advance!
