If we're going to rely on science as a means for reaching the truth — and it's still the best tool we have — it's important that we understand and respect just how difficult it is to get a rigorous result. I could pontificate about all the reasons why science is arduous, but instead I'm going to let you experience one of them for yourself. Welcome to the wild world of p-hacking.
