> Your athletic ability can vary from Usain Bolt to completely uncoordinated; some people have photographic memories (e.g. Lebron James apparently); some people can factor large numbers in their heads (computation), or recite huge strings of digits (non-episodic memory). I'm going to quibble with you. When you say that individual humans vary widely, you're mostly assuming a baseline scale of typical human variation. Which is basically begging the question. Of course the fastest or smartest people look very extreme, when you're implicitly comparing them to typical people. Usain Bolt is very fast for a human. But he's slower than the average housecat. On the flip side some people have really good memories. But even the dumbest humans manage to remember a huge number of symbols compared to what a chimp's capable of. Same for virtually everything else you listed. Food taste, aesthetic preferences, auditory capabilities, intoxicant consumption, etc. Normal human variance is swamped by variance between different animal species. This is mostly invisible to us, because most of our day-to-day interactions are with other people. Not exotic organisms. So I would guess just the opposite. I believe that sensory experiences across different people are very likely to be substantially similar. At least compared to an alien species, or AI, or even just an intelligence from a distant evolutionary branch (like an octopus).
