You guys. We just did a little demo in my research methods class to introduce them to p-values and statistical significance. And I'm super excited at how it went down
The demo was simple. Students pair up. One student, the flipper, flips a coin. The other, the guesser, guesses the result. Flipper tells them right or wrong. Then they switch roles and do it again. Everybody reports their results on their iClicker
Before I show the result, I ask them what they think it'll be. Some say 50-50. Some say not exactly 50-50 because of randomness. Are there other possibilities besides that? We discuss stuff like maybe people are faking-good. Or they can read partner's nonverbals. Or minds. Etc.

This is your semi regular reminder that among players who have been admitted to the NBA, height has no association with basketball performance
And that’s not even getting into the validity issues with the criterion variables
P.S. I don’t have a SoundCloud, instead let me promote this meta-analysis by Kuncel et al. psycnet.apa.org/record/2001-16…

Let's talk cross-lagged panel models! A short example/provocation, inspired by some discussion yesterday
Say you have 2 things you're interested in, X and Y, each measured at 2 times. You want to know does X cause Y, Y cause X, or both? (or if you're shy about saying "cause" you say "lead to," "predict," "is a risk factor for," "Granger-cause," etc.).
X and Y could be anything, e.g.:
* Depression and stress
* A personality trait and a social role
* Parental something and child something else
* This brain region and that brain region

So you decide to run 2 regressions:
x2 ~ x1 + y1
y2 ~ x1 + y1

One of the issues @alexa_tullett, @siminevazire, and I talked about in this episode is a super important and kinda counterintuitive question (b/c superficially it feels unscientific): When should you believe research you do not understand? (thread)
This question was posed really well by @NaomiOreskes, who pointed out that even scientists do not have the subject-matter and technical expertise to evaluate all of the science they consume and rely on ted.com/talks/naomi_or…
Oreskes proposes that we should accept scientific consensus as a kind of argument from authority - but a special one because the "authority" is a community of experts
