So ignore all non-significant results? What’s to say those methods result in findings closer to the truth than the methods with no significant results.

The issue is that so many seemingly legitimate methods produce different findings with the same data.

9 of the teams reaching a different conclusion is a pretty large group. Nearly a third of the teams, using what I assume are legitimate methods, disagree with the findings of the other 20 teams.

Sure, not all teams disagree, but a lot do. So the issue is whether or not the current research paradigm correctly answers “subjective” questions such as these.
