My guess is that group brainstorming sucks because people are afraid of being judged for having crazy ideas by other members of the group. Seems like marijuana might solve this problem.
More generally, we could rank various brainstorming methods from least controlled to most controlled:
Current data suggests that "one person sober alone" beats "one person high alone" and "several sober people", but we don't have much data for the high person who's getting directed. Furthermore, it's plausibly the one that's closest to the optimal level of controlledness.
This is a fundamental misunderstanding of what creativity is. Read "Serious Creativity" to dissolve the idea that creativity and craziness are related. (It's actually an optimization and search process -- and as per the Sequences, you can't improve such a process much by adding randomness to it. That is, above a certain small level of randomness, you won't be making things better, compared to changing the higher-level processes as per Serious Creativity. SC's author offers a proper reductionist explanation of creativity, at the, "AI people wanting to implement creativity should read this" level.)
First allow me to show you my preliminary data.: http://www.reddit.com/r/bestof/comments/obtqe/its_they_live_these_are_reddit_robots_programmed/
Introduction
I think I may have found a novel use for an old technique, which may or may not have implications for rational decision making. I am open to constructive criticism or even deconstructive criticism if you make a sound argument. Ultimately, I would like the experiment to be put to the test. If you have the supplies and know-how to carry it out, then feel free to try it and report your findings.
