Is the awareness test relevant?

The awareness test (http://bit.ly/fr2qoX) and change blindness (http://
bit.ly/g5laiC) are simple and popular. The tests seem to imply that
most of the time we walk around unaware and that there are gorillas
around (we just don't see them).

My question is: Is the test relevant to everyday life? In other words,
if you meet a person who says "I see a gorilla," what are the chance
that the person is correct, versus the chance that he's crazy?

I don't know. I guess, if you're in a business that is subject to
frequent surprises, you've got to think he might be correct.
