Today, I'm going to make a bold statement. Yes, I am also posting two days in a row, something I have not done for quite some time.
Generalism makes for a stronger mind due to intellectual cross-training, something you get less of by being a specialist.
Many of us have at least heard of cross-training, doing training in a completely different sport to make us better at our primary sport. I'm now claiming that a person can benefit just as much by cross-training in a different discipline. I'm also claiming that a generalist, a person who, by definition, learns about a multitude of varying subjects, effectively cross-trains their mind. Combined with the Pareto Principle (http://en.wikipedia.org/wiki/Pareto_principle), this gives a generalist the advantage.
Granted, true intellectual cross-training makes one more of a versatilist than a generalist.
I have much more to say on generalism as a whole, but you will have to watch out for my new blog on the topic. Yes, you heard that right: the guy who slipped in and out of his blogging coma through this past fall is going to handle two blogs at once. I'll still post on the more general aspects of my life here, but I want to give this other blog a bit of independence.
