Just mindlessly lying in the caption to a photo doesn't engender a ton of confidence that the rest of the article is going to be intellectually honest.
Saying "only one" when it's actually only two out of forty or more is hardly "mindlessly lying". At best it's < 5% error that doesn't change the big picture the article and the caption tries to make.
Doubly so since they actually are correct on who has really gray hair (Norvig) as opposed to the graying/gray-ish hair the other person has.
Ironically all of you are making judgements based on appearance.
What else in the article wasn't intellectually honest?
the problem being that everyone in this picture is 27.
