This is my favorite climate change chart. Japanese monks, aristocrats, and emperors kept meticulous records of cherry blossom festivals for 1,200 years and accidentally built the world's longest climate dataset.

Alphabet, Amazon, Meta, and Tesla paid just 4.9% of their profits in federal corporate taxes in 2025. They have seen their collective tax bill drop by $95B thanks to two rounds of Trump tax cuts. Meanwhile, they've laid off thousands of workers. Trickle-down economics was always a scam.

America now has 935 billionaires with $8.1 trillion in collective wealth — a 20% increase from 2024. Meanwhile, the bottom 50% of Americans control $4.2 trillion in wealth. When 935 people control more wealth than half a country’s population, we have a very serious problem.

My paper "Voter Information and Distributive Politics" has been accepted for publication at the AEJ: Micro 🥳 Ungated version here: osf.io/preprints/so...
Voter Information and Distributive Politics
Benjamin Blumenthal
Abstract
Does more information benefit voters? I examine this question in a novel setting of distributive politics and electoral accountability. Homogeneously-informed electorates can benefit from less information through improvements in the control or screening of politicians. For heterogeneously-informed electorates, I show that the distribution of resources and voter welfare is affected by the nature of informational heterogeneity and by voters’ ability to communicate with each other. When communication is impossible, less-informed voters can be better off than more-informed voters.
