I like this. "Strong opinions held loosely" always struck me as annoyingly hard-headed, but I think the author is able to strike a balance between having an opinion and seeking out new information to get at the truth. Having to have an opinion forces you to really engage with the material in a deep way, instead of just passively absorbing it, doing things that feel like work. It's a cool shortcut; I'll try it next time I'm learning something!
