Abstract
Humankind faces many problems, such as terrorism, crime, the collapse of the family unit, drug abuse, war, theft, etc. I performed this multidisciplinary study to determine whether there were primary and common psychological reasons. I have discovered some fundamental factors that are significantly limited or reversible of human intelligence by some psychological factors. As I hypothesize, these limitations might be due to activating delusional thoughts and decisions, which are the declines in intelligence, mainly caused by psychological mind viruses (MVs). These issues impact optimal living and psychological, physical, and social well-being. Therefore, better practical solutions and preventive methods are needed. The leading psychological limiting factor for intelligence development is MV, and its remedies are healthy mind viruses (HMVs). Intelligent learning, training (meditation), and intelligent decisions might evolve the nature of the brain, nurture, and X-ultra quantum conscious particle genome (X-UQCPG); all six factors seem interdependent.
