“Why are there schools of martial arts, but not rationality dojos? (This was the first question I asked in my first blog post.) Is it more important to hit people than to think? No, but it’s easier to verify when you have hit someone. That’s part of it, a highly central part.” (Eliezer Yudkowsky, Rationality)

Rationality like a martial art, Easier to build an education system when the goals are clear and measurable
