Such predictions could be correct for many situations, but, because they are just predictions, there is a limited guarantee on their correctness. Example: a person was "seen" by a clairvoyance medium. This medium was asked on the status of the heart of that person. The answer was that the heart is in a good shape. The answer was correct. But there was a "little" problem: that person was wearing a pacemaker, which was not "seen" by the medium, in accordance with MDT. MDT can be used to see how to develop such paranormal qualities. First of all, for it, let's remember that XZM are image models and so, developing the interaction with external reality based on image models is strongly recommended. Also, a natural tendency towards image models is mandatory. Such persons must be well balanced, or able to obtain a stability status by different methods, so that the normal structure of models has a reduced activity. Such persons must have a reduced tendency to control the activity associated with the problem (to reduce even more the activity of the normal structure of models). It is also very important to obtain as much as possible information by direct interaction (based on image models) with the problem. The information based on symbolic models could be useful too, after translation on image models. MDT considers that XZM models are image models. But, there is a supposition that some symbolic-models could be illegal too. If so, an XZM-symbolic model could explain, e.g., how some persons can perform extremely complicated arithmetical operations. THE NORMAL HUMAN BRAIN This section was intended to treat the subject declared, but instead, it is just an evaluation of the problem. The reason is the inexistence of sufficient data on XZM models. To make a local model on the normal human brain, we take some conditions from MDT, as follows: C1: The PSM must act to protect the being and to ensure the unconditional survival, forever, of that being. The PSM must also contain some models associated with the society in which the being lives. The PSM must not contain ordinary models. C2: Any model of the brain must be stable (harmonic or logic). C3: The whole structure of models must be stable. That is, any truth of any model must be accepted (or at least not rejected) by any other model of the brain. Let's develop a little this local model. The main condition of normality is that the person has to be accepted by the society. That is, the person has to integrate in that society. For a cannibal- type society, the person has to integrate in that society. Otherwise he will be rejected by the society. The limits or normality are, as we see, very broad. For a democratic society of our time, some of the conditions of normality are "not to kill", "not to steal" and so on. Such models must be in the PSM and this goal is achieved by education since many generations.
