Let's consider that a person makes a model to kill someone. If this model is blocked by PSM, that person can be considered as a normal one. However, if a person makes a model to kill someone and, in some conditions, the PSM does not work properly, that model can be activated. Based on MDT, such a situation is a hardware problem and so, that person is not a normal one. In "classical" psychiatry, they make a test to understand if the person was or not responsible for his/her acts. Based on MDT, as I said, here we have a hardware problem and so, the fact that the person was or not conscious of what he was doing is not relevant. Even more, based on MDT, a model cannot be destroyed by any hardware or software facility of the brain. So, a punishment has no effect. If a brain has a hardware problem, there is no solution to correct it. The main reason is the fact that any model is connected with almost all the models of the brain. Even XZMs must have some connections. In order to remove a model by external action, it is necessary to know the exact hardware structure of that brain and this, as I think, will be not possible at least in the next 50 years. C1 asserts also the condition that the brain must not contain ordinary models (O.M.). This condition is necessary because if an O.M. is included in PSM, that model becomes invariant (it cannot be changed by any information from the external reality). So, if an O.M. is included in PSM, any information obtained by IR from external reality must be compatible with that OMPSM. If not, that information must be distorted to meet, somehow, the condition requested by the OMPSM. When there is an OMPSM in the brain, this is an illness called "paranoia". A person with an OMPSM must distort the information obtained from external reality to meet the conditions requested by the OMPSM. Example: The authentic communists have included in PSM the OMPSM called "the working class is the leader of the society". Regardless of the external reality, they have a harmonic/logic structure of models based on this model. Fortunately, the absolute majority of the communists have no such model included in PSM and so, they are normal persons. Example: Usually, drugs create an OMPSM called "use them". Such persons will continue to use drugs regardless of any information associated with their negative effects. This is a special kind of paranoia. Example: smoking is also a form of paranoia, due to the same reason, as above. After many years of smoking, some persons can give up smoking. This could happen if, for instance, the person gets ill. The illness could make a non- smoking model, which enters the PSM too.
