I think this is tosh. To prove the thing either way you have to do the
same amount of work, you have to assess the instinctive abilities in some
quantifiable way of a statistically significant number of humans. This
significant number is the same which ever statement you are looking at. I
can see no way in which the statement "No humans have an instinctive
ability to swim" is easier to prove than "All humans have an instinctive
ability to swim".
