>has been previously estimated to affect between 2 and 2.5 percent of people in the world ... a little later in the article "between 31 and 72 out of 3341" ...a little later "as many as as many as one in 33 people (3.08 percent) may meet the criteria for face blindness" so we go from 2% to 1% to 2.1% to as high as 3.08% Yes, 3.08% (possibly) is more than 2.5%, but it's still a pretty small percentage
