Why is there a Replication Crisis? That is, why are there so many findings in the published scientific literature that can't be replicated, or are exaggerated far beyond reality? There are four proximal reasons, and they are: fraud, bias, negligence, and hype. In this talk, I'll discuss all four, giving examples, and will also discuss the ultimate reason for the Crisis, which is to do with our current academic system and its incentives. I'll also propose some potential solutions that might put science back on track.
