I think the population of those who apply when they shouldn't, and those who don't apply when they should, are probably different populations. In some cases, you want the population of people who are overconfident, or able to "fake it 'til you make it". But in many cases, you want the population who respect the project requirements as being real, and those might be the same people who treat the job requirements as being real. So, in at least some cases, you have created an anti-filter that will let through unsatisfactory candidates, but keep out satisfactory ones.
