Early Intervention for Learning Challenges
Social stigma around receiving mental health treatment.
Pediatricians are generally not experts in identifying or treating mental health.
Identification is complicated and expensive (both for cost of services, and lost wages due to time off work for parents)
Skill-related fitness is very modestly heritable. Being good at a certain skill is mostly due to sheer amount of practice and just devoting a lot of time, hours, and concentration towards one subject. While some people certainly exhibit greater talent due to a higher heritability quotient, this is not necessarily the case.
