In the chapter of Freakonomics called ?What Makes a Perfect Parent??, we analyze the data from the U.S. Dept. of Education?s Early Childhood Longitudinal Study, and argue that many things that modern parents do to make their kids ?smarter? (i.e. culture cramming), doesn?t have any effect on early childhood test scores. Apparently we?re not the only ones who think this is so.He's right. Parents commonly do a lot of things that are not educationally helpful.
