"Eating this during pregnancy doubles the baby's risk." "This additive raises the odds of developmental problems by 1.5 times." Parenting information contains a relentless stream of articles that use numbers to amplify parental anxiety.
Those numbers may not be wrong. But numbers without context mislead. If the underlying risk was 0.1%, a "doubling" still leaves it at 0.2%. The story of one in a thousand lands in a parent's mind as "my child is in danger."
Statistical literacy is not the ability to distrust numbers. It is the ability to read them correctly. A handful of concepts is enough to change how you receive parenting information.
