My biggest learning opportunities in science have come from watching two intellectual heavyweights engaged in robust debates. Unfortunately, it seems increasingly common for people to infer mental or emotional states of their fellow debater, which derails good debate. Reasonable etiquette in science is critiquing the expressed ideas and methods rather than the person (or what has been inferred).
