Everyone has heard that one quote from Einstein about fish and bicycles. (EDIT MONTHS LATER: wow bicycles? for real? it’s a fish and its ability to climb a tree? This got past my own proof-reading in a post about intelligence? A little ironic…) It does relate strongly to this discussion, but I didn’t want to be predictable and include it as the main statement. I then accepted that it was probably inevitable that it would crop up somewhere in any discussion on intelligence whether I planned it or not, so I got it out of the way here. Now we can begin.
