Well the comment you replied to said: > the US (obesity, pollution, circadian cycles disruptions, etc.) is also the country with the smallest measured drop and you said that the US is known to lie (with so many examples). So for that above to be a lie, many people across different states need to work in unison, delivering false results. Also nobody really knows if this effect is really there to begin with, let alone knowing what causes it. People lobbying so organized across the states against an unknown is very unlikely.
