Letter from FBI Director Kash Patel firing veteran FBI agent Walter Giardina, whose wife died of cancer last month at age 49. Patel accuses this agent, a Marine combat veteran, of โ€œweaponization.โ€ Many of his FBI colleagues told me he did his job scrupulously and ethically.

New executive order puts all grants under political control All new funding on hold until Trump administration can cancel any previously funded grants.

It's been obvious for a while that they were headed in this direction, & this attempt almost certainly won't go unchallenged, but you need to understand that this is & has been America's Lysenkoism moment knocking on the door, & it has to be resisted every way it can.

Abstract for the paper: The P-curve (Simonsohn, Nelson, & Simmons, 2014; Simonsohn, Simmons, & Nelson, 2015) is a widely-used suite of meta-analytic tests advertised for detecting problems in sets of studies. They are based on nonparametric combinations of p values (e.g., Marden, 1985) across significant (p < .05) studies and are variously claimed to detect โ€œevidential valueโ€, โ€œlack of evidential valueโ€, and โ€œleft skewโ€ in p values. We show that these tests do not have the properties ascribed to them. Moreover, they fail basic desiderata for tests, including admissibility and monotonicity. In light of these serious problems, we recommend against the use of the P-curve tests.

Paper drop, for anyone interested in #metascience, #statistics, or #metaanalysis! @clintin.bsky.social and I show in a new paper in JASA that the P-curve, a popular forensic meta-analysis method, has deeply undesirable statistical properties. www.tandfonline.com/doi/full/10.... 1/?

The economy is on the precipice of recession. Thatโ€™s the clear takeaway from last weekโ€™s economic data dump. Consumer spending has flatlined, construction and manufacturing are contracting, and employment is set to fall. And with inflation on the rise, it is tough for the Fed to come to the rescue.

Unemployment remains low, but thatโ€™s only because labor force growth has gone sideways. The foreign-born workforce is shrinking, and labor force participation is declining. Telling is the economy-wide hiring freeze, particularly for recent graduates, and the decline in hours worked. 

Itโ€™s no mystery why the economy is struggling; blame increasing U.S. tariffs and highly restrictive immigration policy. The tariffs are cutting increasingly deeply into the profits of American companies and the purchasing power of American households. Fewer immigrant workers means a smaller economy.

Any notion that the economic data misrepresents the reality of how the economy is performing is way off base. There are revisions to the data, even big revisions, but they universally say the economy is doing worse. Thatโ€™s because it is. 

BTW, the DOGE cuts are a key factor in the revisionsโ€”not because BLS has cut staff, although that canโ€™t help, but because the government often reports payrolls to BLS late. It didnโ€™t matter when government employment was stable, but now that itโ€™s declining, the cuts are picked up in the revisions.

Under Pressure, Psychology Accreditation Board Suspends Diversity Standards As the Trump administration threatens to strip accrediting bodies of their power, many are scrambling to purge diversity requirements.

Extremely disappointing & cowardly. The American Psychological Association is rescinding diversity requirements. Not due to any actual mandate from the federal government, but only because it may *someday* face pressure from the government www.nytimes.com/2025/03/27/h...

At this point, I might as well --
Here's an infographic showing different ways to include age as a predictor. The top shows two extremes, just as a plain old numerical predictor (imposes linear trajectory) vs. categorical predictor (imposes nothing whatsoever). And then three solutions in between!

For MAGA, Ignorance is Strength Research cuts arenโ€™t about shrinking government, theyโ€™re about killing science

"two first-rate economists, David Cutler and Ed Glaeser, have made a stab at estimating the impact of cuts at NIH. Their analysis suggests that these cuts might save $500 billion in federal spending over the next 25 years โ€” while imposing more than $8 trillion in losses."

A tricky thing about modern society is that no one has any idea when they donโ€™t die.

Like, the number of lives saved by controlling air pollution in America is probably over 200,000 per year, but the number of people who think their life was saved by controlling air pollution is zero.
