The statement “Ninety percent of all the scientists who have ever lived are alive today” is completely false. The total number of human beings who have ever lived is approximately 110 billion whereas the the number alive today is probably a little less than 8 billion. Therefore the percentage of all people who have ever lived who are alive today is less than 8%. And you’re telling us that the percentage for scientists is so disproportionately more as to be 90%? This misleading statement casts doubt on the credibility of your entire article.
