I have no idea if this study has any weight at all but I do know that I have a high degree of focus. When I was a kid I would focus so deeply sometimes my dad had to physically shake me to get my attention.
Never had my IQ tested though so no idea if I exhibit the correlation or not.
How is your statement relevant to either the article or the article headline? The news is just that there's a correlation between A and B, which suggests that either A causes B, B causes A, or A and B both relate to some third factor C. Where did you see an unjustified claim of causation?
