The aim of this text is to show how, using the achievements of modern computer science, psychology and neurobiology, we can search for an answer to the question about the a priori mechanisms of shaping a phenomenal image of reality given by experience. This phenomenalism statement is very close to, so called, Bayesian model of mind by Karl Friesen. The author asks how in massive scale to reach the cognitive processes taking place without representation, outside the field of consciousness, which influence the formation of this model of the world. The result of the consideration is to be a neuromachine project whose task will be to automate and mass research of hidden cognitive attitudes. Its activity is to become a real alternative to opinion polls performed in the paradigm of the so-called declarative sociology, which do not provide results significantly reducing the risk of decision-making in management.
