I've long been interested in seeing debate formalized. That is, a back and forth structured discussion with the end goal of arriving at a narrowly scoped truth. One strategy for winning could include attacking core assumptions underlying an argument, thus weakening any claims that followed from that assumption (question the methodology/replication of a study that claim vaccines cause autism). The problem I have with debates in popular culture is that it's often performative and participants devolve to whoever is best at dominating a discussion, or whoever is the more eloquent with not much light at the end of the tunnel.
