There are two remedies: Thinking about the ideas, and reading other people's thoughts about the ideas.

I generally recommend the former first, followed by the second, followed by the first again - don't read too much without giving yourself time to think the ideas through for yourself.

My general rule with new ideas is to get the summary first and think it through - my personal goal is to have (at least) one criticism, (at least) one supporting argument, and (at least) one derived idea before I read other people's thoughts on the matter.
