I've been working on a side project over the holidays related to this, but nothing to share yet unfortunately. Suffice to say, I would love it if we could frame discussions around specific policy issues, and focus on listening to one another and prioritizing and agreeing on problems as a first step before jumping straight into political rhetoric and speaking only to one's own base or those who already agree with you.
Also somewhat related - the history of decline of political discourse is staggering. Apparently in the US, Abraham Lincoln used to debate by having 90 minutes of uninterrupted complex analysis. This has been replaced by modern debate formats like those popularized by the Jubilee YouTube channel which optimize for 10 second clips.
Interestingly, there is a counter movement where long-form interviews are becoming popular again among niche crowds who actually want to hear and discuss issues. Joe Rogan, Jordan Peterson, Lex Friedman, Sam Harris, Destiny to name a few. I don't think we've seen the end of the changes for these discussion mediums. Hopefully we'll see changes for the better!
