Modern man is surrounded by numerous and varied streams of information. The social environment has many sources of powerful information that impact man, his consciousness, and his subconsciousness. Therefore, the problem of the psychological security of the person is increasingly becoming realised. The influence of information from the social environment on man is determined not only by his personal characteristics but also by his biology, where psychology and biology are inseparably linked. Physical health depends on mental health. It is therefore important to examine the information security of man not only from the social point of view but also from the biological point of view. The latest advances in science require a review of the concept of ‘information’ itself and adoption of the concept of world order based on the Information-Energy Doctrine as a synthesis of advanced knowledge. The time has come for a new scientific discipline in psychology: information psychology.
