I once read a study of a New Guinea tribe that ate defeated enemies. It was noteworthy that they just cut up the bodies on the spot and ate them raw. Again, cooking does not denature all proteins equally. Smaller proteins may be denatured less than larger ones. Prions are not large proteins, even though they can have different structures. And just one surviving prion will infect you. This is just theory, for which I cite no sources; however one thing we could do is to go to a major proponent of prions and ask about this question. To the endless argument between Henson and Stodolsky: The idea of memes developed by analogy with genes. It suffers badly from the simple fact that ideas do not work like genes. They are not, unlike genes, individual traits which together combine into a complex thing, but meld and twist into one another at all levels and combinations. Second, so far as I can see, biological psychology is merely another set of words to describe sociobiology. To draw connections between our behavior and our biological history is HARD, and hardly a job which can be done as lightly as Henson and Stodolsky seem to assume. Although they're hardly identical subjects, a bit of consideration of how our brains would also needs to be used, simply because it will test out whether some way of thinking or algorithm is really the one we actually use. (Minsky fails badly on this issue). Not only are such connections hard to make, but our behavior including our social behavior depends on other factors than just our genes, as it should. It seems to be among the most labile traits of animals: monkeys which in one setting develop a hierarchical society will in another live much more independently. What this does to the notion that our biological history will explain our present behavior I will leave unexplained, except that such an idea becomes far less plausible. I do find references to various ideas generally interesting, and will try to find Sheets-Johnstone. I don't like any discussion containing ideas with no attribution (when there is one), mainly because "he said that he said that he said that he said" often destroys the original message in the original source.
