While we shouldn’t fall for junk science, we also shouldn’t fall for cynicism as an excuse to stick to our priors. It might not replicate if you try to do so, but until someone does, we shouldn’t write it off.
They are both making claims. (And I think usually most people are making some sort of claim, unless they are just nitpicking). One is claiming that they remember a study — pretty vague, and easily proven (as far as we can tell at least) by just showing us any study. The other is claiming that that study doesn’t replicate… without having seen it, which seems like a pretty high bar to clear.
