The evidence discussed to date suggests that opioid  peptides play a specific role in some aspect of the neural  system underlying the expression of palatability, the opioidpalatability  hypothesis. In order to evaluate fully this idea in  humans, an alternative measure of orosensory reward is  needed in order to get around the potential problems of  interpreting hedonic rating data. One approach has been to  examine in detail changes both in eating rate and the pattern  of changes in subjective appetite during meals following  manipulations of palatability alone [79]. Increasing the  rated palatability of a food increased intake and also resulted  in increases in rated hunger during the early stages of the  test meal [80].

To begin with this fragment we’d like to note one evident problem we constantly have analyzing the higher spheres of human activities. Generally, the psychology as well as other social sciences always face a difficult dilemma. On the one hand, the scientific status, which like a burden is carried by the same psychology or sociology, requires knowledge convertibility and nearly mathematical precision. On the other hand, from the same mathematical point of view the brain and the inner world of a human is such a complex system that can’t match a mathematical body, even if all data is available. The phrase “even if all data is available” is a bolder presumption then the presence of any such mathematical body. Alas, modelling a human is a faraway future challenge. Maybe then the answer will be given if it’s possible at all.
