Unfollowing toxic social media influencers makes people less hostile!
In 2 experiments, we found that unfollowing extreme influencers:
-Reduced partisan animosity by 24%
-Increased satisfaction with X
-Led people to share higher-quality news
Effects lasted for 6+ months.

In economics, editors, referees, and authors often behave as if a published paper should reflect some kind of authoritative consensus.
As a result, valuable debate happens in secret, and the resulting paper is an opaque compromise with anonymous co-authors called referees.

Wikipedia is the last good website, the one staple of the early internet that hasn't been degraded by pursuit of profit.
It's not an acceptable academic source—it's subject to change—but it's a great first cut, and has citations to acceptable sources.
