I have enjoyed this article series many times in the past. Having been in all three classes, he got losers and clueless correct, but he is mistaken on the sociopaths.
1. Sociopaths don't recruit. They build fiefdoms and leverage social ties. How many times have you seen a random guy making minimum wage become senior management? Almost never. The exception to this is people who are hired to be in the running for senior management who are moved all over the company at a fast pace to get the lay of the land.
2. Losers are sociopaths who do not have the birthright to be sociopaths. Put the other way around, sociopaths are losers born into valuable social ties. Their natures are the same. Power corrupts. Most people never learn what they become with power. The clueless are the strange ones, the glue that holds everyone together and keeps the lights on.
3. As the author says, gametalk is obtuse discussion distinguished by the stakes involved. That is normal human social patterns, only distinguished by the stakes. If direct, straightforward discussion was the norm, we wouldn't need to use adjectives for it. The clueless are once again the outliers of the organization. The stakes and who gets to use them are the dividing line once again.
It's hard to think that most people are so selfish they would throw their group and others under the bus for benefits, but if you look for it, you will see it everywhere. Most people do not have the ability to exercise enough power to make it obvious.
Think about Resume Driven Development. Half of it is clueless people genuinely excited for Brand New Thing, but what about the rest? They know that in five years, companies will demand ten years of experience in Brand New Thing. So what do they do? They push for Brand New Thing wherever they can. This lets them accumulate leverage for their next job. Who does this hurt? Their company and everyone who has to deal with their Ball of Mud when they leave. This is the moral equivalent of some senior manager taking short-term gains at long-term loss to grab a fat bonus and fail upwards into another company.
I really enjoyed the series, but it has the same problems as other realpolitik subjects. Clueless will grab onto it thinking they can become the next Alexander the Great or Jeff Bezos and make a fool of themselves. The essential ingredients are never spoken out loud, and topics like this are always gross oversimplifications by their very nature.
