> The kind of guys that would steamroll the rest of the team as a bunch of idiots for not agreeing with him, but flip to a charismatic "ah good point" when incontrovertible proof of their idea not being correct was presented. The problem is you can't provide incontrovertible proof in real time in most cases, and lots of managers confuse their passion/certitude for correctness.
The problem is not that incontrovertible proof cannot be provided real time. Yielding evidence from complex, esoteric systems is always difficult and time-consuming.
The problem is the well-spoken people in the above example are not well-listening. Hearing a poorly-worded argument whose conceptual outlines might be worth considering is an important skill. Ignoring an argument because it is not eloquently delivered is hubris.
Because such people do not listen well, they cannot claim to have “Strong opinions, loosely held”. Requiring hard-to-yield evidence before changing one’s mind is “Strong opinions, tightly held”.
In the end, heated arguments are usually an indicator of dysfunction, even in high functioning teams. Teams are usually better off having honest, dispassionate debate.
