Reposting something that I originally posted elsewhere:

I'm reading Rationality and I'm paraphrasing/summarizing the posts so that I understand and internalize them better. I got to Focus Your Uncertainty, and it felt a bit more opaque than the others, what with all of the sarcasm and italics. I compared my summary with the wiki summary, but I felt like the wiki summary was sort of like a dictionary definition that uses its own word. I'd appreciate it if someone could give me feedback on my summary:

Even when you don't have an explicit prior to refer to, you still have an implicit, intuitive prior that is more likely to be accurate than a prior that assigns equal probability to all outcomes, and you should use it.
