ICYMI: I sat down with political scientist @samuel-bagg.bsky.social to discuss the crisis in our information environment and its roots in social identity.
The cure for misinformation is not more information or smarter news consumers
Political scientist Samuel Bagg explains why social identity is at the root of the misinformation crisis -- which calls for something deeper than factchecking.

Quick reminder:
Money invested in climate protection yields many times its value. 1€ = 4,80€ (see link). So if there are conservative (and even worse) parties that actively prevent this, the logical conclusion is that these parties are destroying prosperity.
