The staff of PUP interviewed 23 Harvard graduates, alumni and faculty, asking each “Why do we have seasons?”...The PUP interviewers found that 21 of the 23 interviewed could not explain why we have seasons, a topic that is taught repeatedly in school http://cmap.ihmc.us/Publications/ResearchPapers/TheoryCmaps/TheoryUnderlyingConceptMaps.htm http://cmap.ihmc.us/Publications/ResearchPapers/TheoryCmaps/... I don't find it strange or alarming. No more than the fact that a dog who has learned to bark on command doesn't automatically know how to kneel on command. Memory is an odd thing though. I mainly remember why the earth has seasons now (though I always knew it) because I remember the study that I quote above.
