One of the counterexamples given here, in which the organism anticipates a future shortage, is not a situation in which transitivity is violated. In this case the organism is acting on a lack of knowledge of the future and playing it safe. This is not a failure of the logic of transitivity, but a great accomplishment of life: the ability to accept that one doesn't have all of the information and to manage regardless. The authors are essentially doing the same thing by suggesting that our preconceptions of logical behavior don't cover all situations!
Can we please try to make the content behind the links more transparent in the future? I'd like to know which one is the new story without having to scan through them all.
