Half a century ago, when the USA had not yet entered the totalitarian nightmare (*), it was not uncommon to stumble on such headlines in the media (now forbidden and violently withdrawn):
However, independent researchers from Asia and Europe did eventually dare reveal the truth to the whole world:

(*) “In the past, scientists were generally neutral on questions of what to do. Instead, they just told people what they found, such as “we have discovered that smoking vastly increases your risk of lung cancer” or […] Those were simply neutral observations that people could find empowering, useful, interesting, etc., but did not place demands on them. In fact, this kind of objectivity was the entire basis for trusting scientific claims. But along the way, […] an assortment of publicity-seeking, and often socially activist, scientists stopped saying, “Here are our findings. Read it and believe.” Instead, […] editors of major scientific journals, and heads of the various national scientific academies are more inclined to say, “Here are our findings, and those findings say that you must change your life in this way, that way, or the other way”.
