The linked paper “Hierarchical Complexity: A Formal Theory” is very interesting and quite short. If you ignore the references it is only 12 pages long. It starts from the very simple case of explaining how to formalize the idea that (1+2)*3 is more complicated than (1+2)+3. The paper develops its mathematical theory rather quickly. I was surprised the authors managed to create a psychological theory that was concrete enough to apply in practice. The authors describe the results when they used their theory to analyze two different studies.
Of course many methodologcal issues remain. However I was very impressed. If you are comfortable reading abstract math I recomend the paper.
I had alot of fun helping to co-organize the NYC SSC meetup. I was wondering if people had advice on what questions to use an icebreaker when welcoming new people into the rationalist community. Here are two questions I have tried at the SSC meetup:
-”How long have you been reading Scot?” : Some people found this question obvious and uninspired but it worked pretty well.
-”Has Rationality has had direct practical benefits in your daily life?” : I think the later question would have worked better at a “lesswrong” not a SSC meetup. A common feeling was they valued “rationality” in discussion and weren’t especially interested in using rationality for self improvement.
Does anyone have suggestions for better questions?
