“My research shows how pet ownership reflects complex personality differences, even when it comes to philanthropy.” A new study by professor @herbertchang.bsky.social ’18 finds cat owners donate slightly more, more often, and more diversely than dog owners. Yet, people without pets donate the most.

“Productivity slows down, firms get smaller, sometimes they go out of business.” @dartmouthecon.bsky.social professor Ethan Lewis explains what happens to companies that don’t get H-1B visas, which the Trump administration recently put a $100,000 fee on, via @marketplace.org.

Will the $100k fee on H-1B visas help U.S. workers?

The fee will likely help some American workers in the short term. But over time, the U.S. economy could suffer from failing to attract the world's best scientists and engineers.

“This isn’t a problem that can be fixed at the grassroots level alone.” Research from @prl.bsky.social, co-led by professor @seanjwestwood.bsky.social, finds most attempts to reduce partisan animosity are modest and fleeting. Structural reform and civic education are key to lasting depolarization.
