Even with the discussion section, there are ideas or questions too short or inchoate to be worth a post.
This thread is for the discussion of Less Wrong topics that have not appeared in recent posts. If a discussion gets unwieldy, celebrate by turning it into a top-level post.
Complete randomness that seemed appropriate for an open thread: I just noticed the blog post header on the OvercomingBias summary: "Ban Mirror Cells"
Which, it turned out when I read it, is about chirality, but which I had parsed as talking about mirror neurons, and the notion of wanting to ban mirror neurons struck me as delightfully absurd: "Darned mirror neurons! If I wanted to trigger the same cognitive events in response to doing something as in response to seeing it done by others, I'd join a commune! Darned kids, get off my lawn!"
