Filter
If you continue to look in corners and under rocks, you sometimes come out with more information that NEEDS to be looked at.
Looking under rocks is not bad in and of itself.
But when someone says there might be a live elephant under that little rock, I'm not going to bother to turn it over and see. That's the whole point of the idea of having a mental "filter." You have to be able to discard ideas that CAN'T be real.
