Wouldn't it be nice if policy changes were accompanied by an A/B testing plan to evaluate their impact? I have always thought so. I have also seen a major pitfall of A/B testing that real humans can hand-pick and slice data to make it sound as positive or negative as wanted. Nonetheless, the more data the better.

Yeah, let's do that for everything: safety belts, safety on gun triggers, melamine in milk, etc...

Do you A/B test your comments too?
