It depends on the subject being discussed. If it is something that the redneck is experienced in, I'd go with the redneck, and vice-versa.
If it is something that I do not expect neither to have detailed knowledge of, I'll base my trust on the transferability of the domain. So, for example, a nobel price winner in physics will still have a reasonable understanding of chemistry, and thus cooking.
I'd simply expect a scientist to have finished 4-8 years more in school, and to have spent several decades with smart and learned people. Again, depending on the subject being discussed.
There is also the case to be made that a Nobel price winner will have a reputation to uphold. Going on the record saying silly things will hurt him more than someone that has no reputation. Though I'm less inclined to this reasoning, as this assumes that reputation is something important to the Nobel prize winner.
