How do you explain Dachs, then? Gamma mutation?
I don't really know how to "do my homework," but I know plenty of intelligent people, on this site and others, which can get good ideas from. And yes, I know not to stop at just one book. I've assembled 6-7 books on ancient Egypt alone, and then I'll move on to the ancient Near East (Israelites, Phoenicians, Mesopotamia, etc).
Easy, Dachs did his homework. Then he picked an audience where he could for sure be "the man" aka CFC. Creating the brand of "being the man" immediately spawned an arms race, he continues to do enough homework to remain "the man", while folks like Owen go Justin Gatlin and break his old world records while he keeps powering forward.
Meanwhile, to maintain the trophy's very existence and attention that comes with the knowledge, Dachs makes sure to shame anyone he perceives a faker, resulting in all the people who fall for the appearance of intelligence rather than the substance of it will fall for his own self-grown cult. It's a popular hip-hop technique, which is a pop-culture you will notice all our young historians are wise to. But note that faker is relative to the bar he sets, which is why CFC is his forum. One of the largest non-expert bodies of history lovers. Aka people who will sing his praise.
Shaming his opposition, lame in of itself, has a cool result in this case though. It ups the ante of what's needed to remain the man. He picked a good enough audience that his competition will be successful in outing him to us non-experts if he goes Niall Ferguson on us and relies too hard on his position as The Man, and doesn't do his real work.
This means to keep the title he has to do real work that has started at some point to translate to real life success and expertise in the actual field of history. And it also brings to our attention just how for-real history is, and why we shouldn't fake it, and should respect it.
The downside of shaming those less expert is that it discourages people from studying history because no amount is enough to someone you look up to will insult you for learning too little and asserting what you've learned. So while those motivated to compete compete harder, others who would have contributed real stuff drop out entirely.
So the cool thing about Dachs is that he's actual for real about it, and doesn't settle for just looking like the man, even if he adds style on top of substance. The style bit works though--people like me didn't pay much heed until others joined his cult and sang his praises. "I wish I had dachs' brain" said one. I was like "really? him?" then I was like, hmm. A year later, because he's true to his game, I was like, damn, this guy deserves his praise, and now I pay him a lot of attention.
Dachs knew his game and is winning it. You're asking how to win in Dachs game, but you don't want to train for it. You want to look like an expert, but you don't want to be an expert. After all, if you are an actually expert, it means you've sacrificed your expertise in all other unstudied areas because you had to pick and choose.
(Pro-tip, notice how Dachs has defiantly made a case for his animé avatar as cool and respectable and not for teenage posers. His willingness to own that part of him, publicly, relates to why he's willing to actually read for hours and hours knowing no one will ever give him credit for 97% of the work he devotes his life to.)
