Research shows there are no easy fixes to political hatred

A massive meta-analysis of 25 previous studies found that efforts to reduce partisan animosity are largely ineffective, with superficial interventions improving feelings towards the other party by only 5.3%. The effects are fleeting, disappearing within one week, and even repeated interventions fail to produce lasting results.
