In memoriam of Dr. Martin Luther King, Jr.

On this date in 1929 (January 15), the Reverend Dr. Martin Luther King, Jr. was born.

To honor his legacy today, I'd like to share a couple of his important works. Here's a brief excerpt from "Letter From a Birmingham Jail:"

I would agree with St. Augustine that 'an unjust law is no law at all'...We should never forget that everything Adolf Hitler did in Germany was 'legal' and everything the Hungarian freedom fighters did in Hungary was 'illegal.' It was 'illegal' to aid and comfort a Jew in Hitler’s Germany.

The entire "Letter From a Birmingham Jail" is brilliant, insightful, and well worth a read! The full text can be found at http://amp.miamiherald.com/opinion/op-ed/article194707929.html

The "I Have a Dream" speech, an instant classic, was delivered on the steps of the Lincoln Memorial at the March on Washington in 1963. Fortunately for posterity, his speech was recorded in its entirety. Here it is, via YouTube:

Dr. King was assassinated on April 4, 1968. Though the man himself was mortal, his actions, his words, and his legacy of nonviolent resistance to injustice shine as brightly today as they did in the 1960s!

I would like to leave you with two other inspiring quotes from the Rev. Dr. King:

Always remember Dr. King's principles and his commitment to fairness and justice. May we all work with tireless integrity to uphold these principles, in all times and places, and for all people.

Guides to pre-registered experiments

Guides to methodological pre-registration for experiments

If you're like me, you've considered doing a pre-registered study but put it off because you weren't sure what to expect or how much paperwork there would be. I've become a big proponent of open science [I'm working on a future blog post on the topic], as I think it's crucially important to make your materials, data, conclusions, etc. available to other researchers and to the wider public!

As Simmons, Nelson, & Simonsohn (2017) wrote, pre-registration and full methodological disclosure are crucial to the credibility of psychological research. If we want to be taken seriously as scientists, we should behave in accordance with the highest standards of scientific integrity...and that includes pre-registering our studies.

Why pre-registration? Two big reasons: 1) it prevents us from fooling ourselves about our own research findings, and 2) it gives us something we can point to and say "Yes, I planned to do that all along!"

And if we didn't actually plan it all along, it forces us to face the facts—which should serve to keep us humble.

Despite what some people may think, increased transparency is good for science. Period. Sanjay Srivastava gives the topic a thoughtful treatment here, and I agree with him. Our priority should be high-quality science first, PR/funding concerns a DISTANT second. If we have good science in the first place, many of the other concerns will evaporate.

So, here are two resources to give you a good overview of the pre-registration process, and to guide you through what's required:

• A pretty comprehensive 22-page overview openly available on the OSF: https://osf.io/sn6by/
• A much briefer blog post by James Bartlett, a PhD student in the UK: https://bartlettje.github.io/2017-03-29-effective-preregistration/
