Which doesn't mean we should overstate those weak correlations as casual. Parents do read things like this and it creates an enormous amount of stress to see the "science" pull in so many different directions. The only real ways out are to just follow the research that backs your own preconceptions or give up on following the science at all and just reason from first principles and adapt dynamically to your child. The former is where most people end up—cherry picking the studies that "prove" they're already right—and the stronger we state the results the worse that effect becomes.
