Not necessarily true, but you do use a common misunderstanding of averages. Consider this simplified case involving weights. Take 10 people, and let's say that 9 of those people weigh 100 pounds. The 10th person, however, weighs only 65 pounds. Thus, the average weight is 96.5 pounds. As you can clearly see, 9 of the ten people weigh more than average. Only 1 of the 10 is below average
Interesting if we were discussing a population of 10, 9 of whom weighed the same.
Not so interesting as we are discussing a classic bell curve distribution of intelligence across the entire human race.
There are more interesting points in this survey, such as who are the 16% of JW's that think many religions can lead to salvation. LOL
The headline 21% mentioned in the subject line are composed of belief in a personal God (6%), impersonal force (12%) and don't know/other (3%).
I venture that the 6% of 'atheists' who believe in a personal god are not normally allowed out on their own, except on Sundays to go to Church of course.
