This can be said about a lot of individual studies, but it leads to missing the wood for the trees. We need seemingly trivial studies because they accumulate towards a greater understanding of our world and ourselves.
Also you can’t have the big interesting surprise results unless you are testing something where the answer seems obvious. This study seems fine.
isn't this the case for many studies in the past decade? just confirming what we've known all along
