Dropping Conditions that "Work": P-Hacking Your Way To Fame | Part 2 of 6

This video is part of a series of videos on p-hacking, what it is, and why it’s so dangerous for science. I give a pretty detailed high-level explanation of p-hacking in the first video in this series, so if you’re not familiar with the idea, please have a look there first. I’ll put a link to that video below. But in a few seconds, researchers are motivated to get what’s called a p-value to be below a threshold of .05. If they do that, their findings are considered meaningful and they can typically publish their results. If they don’t, well all their work is largely wasted. And to get those p-values below .05, there are some very dubious and unethical approaches they can take. In this video, we’ll dig into one of those unethical approaches that researchers can use to p-hack their data...by dropping experimental conditions that “don’t work.” Welcome to Data Demystified. I’m Jeff Galak, and in this video we’re going to dig into one of the key p-hacking approaches: dropping conditions that “don’t work.” So let’s jump right in.
