I believe that childhood experience completely causes*:

• Most differences in intelligence up to at least the level required to comfortably achieve a college degree in most subjects.

• Most differences in physical coordination and physical quickness in people of similar size.

• Most behavior issues, such as violent acts, crime, bullying, and suicide.

• Most emotional issues and psychological distress.

• Most cases in these psychiatric disorder categories: depressive; bipolar and related; anxiety; obsessive compulsive and related; feeding and eating; trauma and stress or related; dissociative; somatic symptom and related; sleep-wake; disruptive, impulse control and conduct; substance related and addictive; personality; and paraphilic.

• Most of cases of ADHD.

• Most cases of high functioning autism.

• Many cases of schizophrenia spectrum and other psychotic disorders.

I also believe that childhood experience is a primary contributing factor for:

• Most medical problems that are treated by primary care physicians.

• Many other medical problems.

• Susceptibility to dental problems.

*Completely causes means that if the effects of childhood experience are removed, the condition listed will no longer exist in that person.
