Post your never-tested unremarkable hypothesis here:

Mine is that smokers, being outside more often, will have a more accurate sense of ambient temperature than non-smokers.

In a test group, under my theory, smokers would be able to guess the actual temperature to within one or two degrees, while non-smokers' margin of error would be 5 degrees or more.
