Author of Substack criticizes that even best are only <2/3rds replicated. I am okay just understanding that’s how science works - we’re often wrong and most conclusions are uncertain.

My lesson is just we should update our views of bottom right and upper left quadrants.

The lack of correlation between impact and replicability is driven by low impact high replicability experiments journals (e.g. in poli sci; they deserve more respect) and high impact low replicability journals (aforementioned Soc psych and b-school journals that deserve less respect).

I should acknowledge the author of the Substack post’s point that there is no correlation between impact and replicability.

That’s a troubling finding. But I respectfully suggest there are mixed patterns reflecting the oddities of clusters of fields.

But I have to admit I’m surprised how well sociology journals do given American (but not European) sociology was so slow to take up replication and openness. Still, Demography and other leading Soc journals are moderate impact and high replicability.

The upper right good quadrant (high Replicability, highimpact is mainly top Econ journals.

A few disciplinary patterns stand out: b-school and social psych journals disproportionately occupy the bad bottom right quadrant: low replication and high impact.

Interesting Substack, but especially fascinated by the disciplinary patterns in this figure:

Needed - larger samples, more realism about (the lack of) heterogeneous treatment effects:
-"less than a third of proposed hypotheses were supported... the largest predictor of positive exp. results was sample size"
-"moderation hypotheses were rarely significant"

This reminds me Sassoon’ brilliant interview with Karl Marx. Seems appropriate to post it in this thread:

Relatedly, Masoud and I were just going on about how awesome Donald Sassoon is as a historian of the Left. His book _One Hundred Years of Socialism_ should be required reading by the Left intellectual space Mamdani has tapped into.

My friend Masoud does a nice job articulating what democratic socialism means. I’m not a democratic socialist, but happy to see Masoud’s mentor Erik Olin Wright get some credit.

Our discussion ranges from the distant past to speculation on how AI will affect future inequality.

If you’re a journalist who’s still on Twitter, from now on in your writing you have to replace “the American people want” with “troll bots in Eastern Europe demand”

Being there makes your judgment suspect. I don’t care how savvy you think you are, you’re marinating in a disinformation campaign.

Good riddance.

Doug Downey wants to convince you that schools actually reduce inequality, not expand it. In his conversation with @gtwodtke.bsky.social, they examine how the education system likely compensates for SES gaps and why school reforms are a band-aid fix to root problems.

When states like Colorado passed policies requiring employers to disclose salary information in job postings, what happened?

It increased competition, and raised wages, without harming employment or changing skill requirements.

Improved functioning of markets, helped workers.

Agreed - thanks for posting.

Only real apples to apples comparison is net of arrest and trial. Otherwise you’re comparing apples and oranges. Read more than the abstract - it’s great work and worth it.

Someone thought it was a good idea to make this guy president of one of the world’s best universities.

That compelling figure shows most of the Colorado River goes to agriculture. And most of that goes to alfalfa to feed cows.

While cities have done a remarkable job on water conservation, the biggest problem is basically beef.
