The next time you are told that lead was responsible for decreased intelligence and/or bad behavior in a child, you will know that there is no possible way that an expert can extrapolate from the literature to the child about whom he/she is testifying.

Claims of Lead toxicity in a child producing cognitive disorders, behavioral problems, delinquency, ADHD, etc. all suffer from the same misuse of data.
