Slide titled: The non-experimental psych workaround
- introduction: relies on a causal reading of the literature
- methods & results: implicitly (but never explicitly) causal inference-y
- discussion: only makes sense in terms of causality
- IMPORTANT: add a paragraph that your study was only observational and no causal conclusions are warranted. future longitudinal or experimental studies will surely fix this problem.

International student arrivals to the US fall by 19% The US recorded a 20% drop in student visa arrivals this August, though the full picture remains unclear amid contradictory datasets.

New federal data has revealed a 19% year-on-year decline in international students entering the US in August 2025, including a 45% drop from India, America’s largest sending country. thepienews.com/internationa...

The Economic Geography of American Slavery Founded in 1920, the NBER is a private, non-profit, non-partisan organization dedicated to conducting economic research and to disseminating research findings among academics, public policy makers, an...

Ending slavery increased GDP by 9.1% as slavery reduced the welfare of the enslaved substantially, while only generating minuscule welfare gains to slave owners. Fascinating topic that once again highlights how coercive instructions are economically detrimental!

If you rebrand post-docs as AP non-tt, you have to highlight this no?

Jamal Khashoggi, the Washington Post, and the Cost of Speaking Out As Saudi Arabia hosts comedians and courts gamers, the silenced voice of Jamal Khashoggi still echoes.

Washington Post dismantled the platform Jamal wrote on. Discarded the fellowship they created in his memory.

They fired me unjustly for speaking the truth.

But I’ll never stop talking about my friend, writer, and amazing human, Jamal Khashoggi.

RIP, Jamal.

in Canada, the Liberals were historically unpopular, then Trump started talking about the 51st state stuff, the Liberal leader did a lot of talk about resisting him, and the polls looked like this:

Let's be serious, I do not have the feeling that anyone really has a strategy to attract the people. Top unis will attract them anyway and the rest will stay put.

"Cutting the VAT rate on restaurant meals, for example, was not one of the most pressing priorities coming out of the Munich Security Conference."

Well put, Deutsche Bank. (On the disappointment with Germany's infrastructure fund helping to finance giveaways.)

"New study finds salary benchmarking cuts pay gaps by 25%. Pay dispersion partly arises from firms’ uncertainty about market rates, with key implications for pay transparency policy."

The professor has been fired and senior administrators removed from their post. No mention of this in the New York Times, The Free Press, The Atlantic or other outlets who drove the campus speech moral panic.
