Fwiw, anecdotally my impression is that a more common problem is that people engage in motivated reasoning to justify projects that aren’t very good, and that they just haven’t thought through their projects very carefully. In my experience, that’s more common than outright, deliberate fraud—but the latter may get more attention since it’s more emotionally salient (see my other comment). But this is just my impression, and it’s possible that it’s outdated. And I do of course think that EA should be on its guard against fraud.
