@kknnaabb @_mbdr_ One such credible effort from before vaccines is here. It shows that policies did matter, a lot, but also other conditions (inequality, nursing home population, etc) also matter a lot. Cherry picking one state or another (or one pair) is misleading.

@kknnaabb @_mbdr_ 疫苗出现之前的一项可信的努力就在这里。它表明政策确实很重要，但其他条件（不平等、疗养院人口等）也很重要。樱桃采摘一种或另一种（或一对）具有误导性。
