Ivan Oransky and Adam Marcus put a common statistical test under their microscope, quoting scientists who think it's overused: "Getting statistics right is difficult — and requires careful thought, not just slapping on a p-value and calling it a day. It wasn’t always this way; p-values are only about 350 years old. They’re not the laws of physics. That doesn’t mean we could or should throw them out — although some have — but it means we can make them work better for us."
