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.

The real world isn't A/B tests. No government is going to spend millions on equipment and infrastructure on a congestion zone because some engineers are like "Let's just test this out. I have done zero research on what could possibly happen, but it would be fun to see what the results are."

When you write it out like that, it seems to make total sense! But then you read grant proposals that get funded - in things like the social sciences and humanities, and even conventional science and health - millions of dollars essentially just throwing darts to see what sticks.

Surely you see the difference between working in a development environment and working in production?

The comment to which I replied was referring to the cost, not to the implementation
