Humankind faces many problems like terrorism, crime, the collapse of the family unit, drug abuse, war, theft, etc. I did this multidisciplinary research to find whether there are primary and common psychological reasons or not. So, I have discovered some fundamental factors that are significantly limited or revers of the human intelligence by some decisions making and those limitations might be due to activating of delusional thoughts and decisions which are declined of intelligence, mainly cause by psychological mind viruses (MV) in them, as I hypothesis, here. Those issues are impacting optimal living, psychological, physical, and social well-being. So, better practical solutions and preventive methods are needed. The leading psychological limiting factors for intelligence development are known as MV and its' remedies are healthy mind viruses (HMV). 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 these six factors seem to be interdepended. The X-UQCPG might bond with the X-ultra quantum unique conscious particle (X-UQUCP). However, the X- UQUCP might never evolve or change and it might maintain the uniqueness of the conscious state of a person. The X-UQCPG helps to evolve the latent potential level of well-being and optimal living gradually of the related person. Here, I show the unearthed core of early Buddhist teachings, training (meditation), and decisions inclusive of the 8-fold path may be an efficient methodology for Intelligence evolution. The evolution of nature, nurture, X-UQCPG, psychological well-being, and intelligence might be represented in a theoretical 3D graph. If life after death occurs, when clinical death of a person's finally evolved level, and micro quantum key of the X- UQCPG (+X- UQCUP) might be crucial to natural transmission to bond with a matching and vacant zygote/early embryo of its X-ultra quantum particles and its new conscious state, might depend on the lastly evolve genome of the X- UQCPG. However, there are many more mysterious issues to be solved in future researches, so this might not be a theory of everything on the central theme.
