1-6-11 Lessons learned from riddles o It is often important to view a problem from more than one perspective o We learn that determined questioning from a wrong perspective leads to little or no progress, but once the correct perspective is found, the solution to the riddle is often easily determined o Prior assumptions concerning data are dangerous; Questioning basic assumptions is often productive o Students in parachute riddle assume that man is wearing a common backpack, leading to fruitless questioning; overlook the unexpected in scientific data o Yes/ no questions, properly formed, yield highly useful data o In experiment it is similar to alternative and null hypotheses o Details that do not fit expected patterns are often of crucial importance o Discovering that there are no footprints around the body is inconsistent with most interpretations of the problem and can lead to a quick solution when reexamining it.
