Among whites and blacks, Asians, Mexicans and Puerto Ricans, SAT scores have been rising over the last two decades, or at worst holding about steady. Minority group scores are rising the fastest. It seems like quite a contradiction. You'll never get to the bottom of this paradox by listening to political gas. Politicians understand statistics only just well enough to lie with them.
Baseball is more honest.
In the first half of the season, Ruth bats .290, Jackson .280. Ruth bats .350, Jackson trails again, averaging .340. The batting champ trophy goes to Jackson. Not at all. Jackson had 100, then 150.
