A researcher looking for evidence of extrasensory perception (ESP) tests 500 subjects. Four of these subjects do significantly better (P < 0.01) than random guessing. Is it proper to conclude that these four people have ESP? No, because we would expect more than just 4 out of 500 to have ESP. No, because ESP is not a real thing. No, this could have happened just by chance given the sample size and the significance level. Yes, because they did significantly better than expected.
