Every few years I Google this book and then ask about it book here on PF on the off-chance that someone recognizes it. I cannot nail down anything specific that Google can work with, so ultimately it fails. I'm going to try something different this time that should improve my Google search technique. My question is: what branch of science is this? Here is a synopsis of the book: The book documents an actual experiment carried out in an auditorium of people. The curtain rises to show a table upon which sits a tall, narrow featureless box. Nothing happens for several minutes. Then with no preamble, the box falls on its side. End of presentation. The audience is given pen and paper and asked to explain what caused the box to fall over. There were as many answers as people in the room, but that wasn't what was fascinating. What was fascinating was at what point people decided that the question had been satisfactorily answered. Some simply said 'an internal force pushed it over', some went a little further, positing plausible ideas such as a stiff breeze or a string pulled by someone offscreen; some made elaborate explanations, filling their page, replete with diagrams and cutaways of levers, or blocks of melting ice. Analysts found answers fell on a scale of 1 to 5. 1 being "it just fell", to 5 including diagrams.
