Wanna see something cool?

At the Grammy's in 1976, Ella Fitzgerald and Mel Torme explained what jazz is.

The result? The crowd losing its mind. πŸ”₯

That's only true if repeated draws are independent, which is not the case here. The tension between the tectonic plates builds over time. More tension = higher probability of earthquake.

Controlling for things only works if you have so much data on individuals that whether or not they eat ultraprocessed foods is literally as good as random once you control for everything else. Safe to say, that is almost never the case. People don't randomly decide to eat junk food.

β€œI think that…most researchers think of statistical tests as a kind of annoying paperwork, a set of forms they need to fill out in order to get their work published… They feel they already know the truth…so then they find whatever p-values are necessary to satisfy the reviewers.”

Note to fellow journos: If only one "economist" agrees w Trump tariffsβ€”as evidenced by fact that this particular "economist" is now being interviewed and cited everywhere as only "expert" willing to publicly defend themβ€”consider confirming that he's actually an "economist." Check CVs, for example.

Federal spending is *up* under Trump according to the Wall Street Journal. Chaos is not actually the same as cost savings.

Actual budgeting is a kind of actual policy-making and takes real work spread over real time. Running around breaking stuff isn't that.

Important legal victory: a Texas judge has barred illegal deportations of Venezuelans to El Salvador. SCOTUS ruling that these cases must be tried in Texas does not mean the legal battle is lost.

Opinion | The Democrats Are in Denial About 2024 Party leaders have embraced convenient excuses. This perilous political moment requires more self-reflection and honesty.

Amazing to see how much it’s a settled assumptionβ€”not even worth questioningβ€”that public opinion is a static exogenous force that politicians must optimize around.

Make a nonsense model, get a nonsense finding. Citing Sam Altman as an "expert" is not serious academic research.

Separated Bike Lanes Means Safer Streets, Study Says β€” Streetsblog USA Cities that build protected lanes for cyclists end up with safer roads for people on bikesΒ and people in cars and on foot, a new studyΒ of 12 large metropolises revealed Wednesday.

Never forget, a 13-year study found that protected bike-lanes led to a drastic decline in fatalities for all road users.

ALL ROAD USERS.

And painted bike-lanes? No safety improvement at all.

For sharrows, it’s actually safer to NOT have them.

#RDDers: check it out.

"A Partial Linear Estimator for Small Study Regression Discontinuity Designs"

RDDs can lack statistical power.

Standard approaches focus on large N scenarios.

This paper develops a partial linear estimator for low power RDDs. This estimator outperforms leading estimators.

The most obvious lesson to draw from the leaked Signal chat is that these people really are morons. It's not a public act, it's not a schtick, there's not some secret back room where they drop the facade. They are genuinely stupid, incompetent people.

How SUVs Are Making Traffic Worse As larger, taller sport utility vehicles took over US roads, they also aggravated highway congestion, according to a new study. It’s yet another ill effect of β€œcar bloat.”

A groundbreaking new study found that the surge in SUVs from 1995 to 2019 reduced Minnesota's highway lane capacity by 9.5%.

Less lane capacity --> More congestion
