In this thread, I describe how I questioned DCs by asking them math questions. Most answered incorrectly, but I found one DC who could do math. (Although the last question I asked stumped him.)

Also, as I say in this thread, Paul Tholey did an experiment with lucid dreamers (that’s published) about the consciousness of DCs. In the study, DCs were able to come up with rhymes, answer math questions, and even, apparently, tell the dreamer a word that she didn’t know.
