Researchers describe strong "affective polarization": people feel intense dislike for opposing groups even when those groups often share similar views on key debates such as sexism, racism, and economic policy.

Ellis Pinsky, who grew up in Irvington, New York, has been linked to a large cryptocurrency theft that investigators say happened when he was 15. Authorities allege he orchestrated the theft of about $23.8 million in digital assets. By May 2020, masked intruders were reportedly trying to access some of the stolen funds, but Pinsky apparently no longer had the money. The case attracted attention because of the amount and the age of the alleged organizer.
