What is your evidence that the consistently followed public health didn't deliver the promised results? The US sure didn't follow anything consistently and earned the predicted results.Cool, so make an effort to explain what many people would see as a lack of correlation between govt. response and outcome at the global level(and state level in the US) rather than just saying “lol don’t you even believe in #science bro.”
This is a big problem for public health experts whose recommendations failed to achieve the promised results at nearly every turn. The arrogance to not feel you have to explain why your didn’t work is astounding. Failure of anyone in the profession to own up to anything or convey uncertainty will come back to bite us next time because no one will listen any recommendation. “The public just wasn’t obedient enough” won’t cut it.
I'd suggest reading Michael Lewis' book Premonition to learn more about how the US public health system works and doesn't work. Discussing this topic on the basis of one extremely high level chart is pointless.
