Before commenting, the empathy and perspective taking interventions were presented to the treatment groups. I have two control groups, including one that receives a simple friction placebo.
The aim of the boost was to target participants’ motivation to engage in empathy and perspective taking to better manage conflicting political views and keep a constructive (non toxic) discussion going.
Back to bottom line - In this sample, reducing toxicity online does not seem to work via simple changes in the user interface (nudging). However, boosting appears more promising to preemptively reduce toxicity before important voices are forced out of the public discourse online!
Thanks for tons of helpful suggestions by @simonmunzert @lorenz_spreen @seramirezruiz and many more! Further feedback very welcome!
