Many people don't understand the global geopolitical implications. Increases in the demand for As in the US make it vulnerable to bad actors applying strategic pressure on the global supply!

“In 712 Harvard course offerings last year, every enrolled undergraduate received an A.”
“In another 532, A’s were common enough that the class would have violated the…newly approved grade cap.”
“Together, those courses made up more than half of all undergraduate course[s].”

Many of us were taught that experiments are for testing hypotheses. In Ch 1 of Experimentology, our open methods textbook, my coauthors and I argue for something different: experiments are for estimating the magnitude of causal effects.
I think this reframe matters. 🧵

New article published in Communications Psychology!
Large reaching datasets quantify the impact of age, sex/gender, and experience on motor control.
nature.com/articles/s44271-0…
As we age, we move slower and less precisely—but how much, exactly?
We analyzed one of the largest datasets on motor control to date.
Findings:
Reaction time: –1.2 ms/year
Movement time: –2.3 ms/year
Precision: –0.02°/year

Let’s bring science back to X.
Not influencers. Not grifters.
Just scientists.

This looks like a great book and if I wasn't R-osagnostic, I would use it in my course. Is AI good enough to make it all Python/PyMC for me?

Hitting the nail on the head!

The diagram from Roger Penrose I think expresses the circular dependence conundrum of science nicely. The question isn't "is X real?" but "what does 'real' mean?"

So Bayesians: I'm giving one lecture on Bayes in a full course on advanced regression. What is your go-to example of easy to do with Bayesian stats but hard or impossible in frequentist?

This study, led by the talented Hanna Kossowsky Lev, explores the fascinating interplay between perception and action in haptics.

Spontaneous recovery is a fundamental feature of motor adaptation, implying at least two timescales of learning.
A new paper from @AliGhazizadeh11 finds that reward learning also exhibits spontaneous recovery, and links it to the prefrontal cortex.

Scientists (rightly) trust their eyes more than statistical tests. That's because NHST doesn't actually work. It is empty ritual.

These are all within 2 sigma, how is this considered significant ?
