I do. Do we think economists are actually generating this understanding? I'd be curious to know about policy changes which have been the result of non-obvious insights from the field of economics.

I'd maybe question this a bit. I suspect that many things we consider obvious are only so because of the field of economics -- but that's admittedly only an initial hunch.
Hence economics is a probabilistic field. The things that occur have a probability behind them. Instead of a policy that needs X to happen the policy can be adapted to "If A then B, if X then Y".
