Even worse, it's very likely the author wasn't even right most of the time. They claim a frequent occurrence is that "the room" turns against them. Now, their rationalization is that they are ego-driven, yadda yadda, no other possibility of why "the room" is often against their position. If they were rational as they claim to be, maybe they could show some insight or introspection into the possibility they are wrong about some or all of the details, at least some of the time.
But no, their conclusion is that humans are ego-driven and it's best to disengage and only debate with truly smart people.
This reminds me of the joke about the guy who's driving and hears a warning on the radio: "beware of a madman driving the wrong way on Av XYZ", and he replies "ONE madman!? There are HUNDREDS of them!"
