For people freaking out in the comments: we don't need to change the scientific method, we need to change the publication strategies that incentive scientific behavior.

The most shocking thing to me in this video was the fact that some journals would blindly refuse replication studies.

we should open up a journal for replication studies only

Sadly these incorrect published studies cause people to distrust all of science entirely.

When something is published it's proof that someone with the ability to publish things decided to publish that thing.

Outstanding video. It wasn't until I really started getting into research at MSc level that I began to realise so much of the research I was appraising was deeply flawed. At undergrad, I assumed that it was ME who was flawed every time I saw a glaring error. At that level, you don't have the confidence to criticise the work of experienced researchers.

This is an awesome explanation and it's going to be really fun reading everyone commenting with their confirmation bias while I read their comment with my own biases that I have about what biases they have

Oh sweet brain, such complex things

Cole Turner

An engineer with a masters in nuclear engineering, a mathematician with PhDs in both theoretical and applied mathematics, and a recent graduate with a bachelors in statistics are all applying for a job at a highly classified ballistics laboratory. Having even been given the opportunity to interview for the job meant that each candidate was amply qualified, so the interviewers ask each the simple question, "what's one third plus two thirds?"

The engineer quickly, and quite smugly calls out, "ONE! How did you people get assigned to interview me!?"

The mathematician's eyes get wide, and he takes a page of paper to prove to the interviewers that the answer is both .999... and one without saying a word.

The statistician carefully looks around the room, locks the door, closes the blinds, cups his hands around his mouth, and whispers as quietly as he can, "what do you want it to be?"

Statistics show that 83.17% of research stats are false. (Including this one, of course.)

From first hand experience I know that a lot of researchers (especially in the social sciences or similar) don't even care about research quality. They just want to get their masters or phd done and then leave academia or are profs that don't care anymore about anything and just want a long publication list. They produce tons of useless papers that have no real research but many citations.

True. I read a paper based on 2, yes 2, human subjects. Howled with laughter. Dr. Van Nagakawara (OSU) wrote a paper for the DOT&FAA where he admitted his protocol was flawed and threw in unnecessary facts for we who knew them. Yet it became the Headline:

SCIENTISTS SAY FLYING SAFE FOR ELDERLY & GLAUCOMICS

NO, it's not. Pilots have a glaucoma rate 5-7X the general population. There are good researchers out there, and they will often tell that their paper is bunk.

I feel like everyone in the world needs to watch this video. There's so much crap out there an no one ever thinks past what they want to hear. This should help.
