Reverse correlation Pt 3

I like to refer to this as ‘chicken or the egg’ as sometimes it can be difficult to establish the direction of a correlation. For example, research on reading has shown poorer readers make more erratic movements and more stops per line. Some educators believed that eye muscles must have been poor or not trained properly. So eye movement training programs were developed and administered to elementary school children. It turns out that poor readers have these erratic movements by having slower recognition of words and difficulties in comprehension. Training elementary children to comprehend words more effectively led to smoother eye movements. Where training eye movements didn’t improve reading comprehension. Another example, research on altruism has correlated that people who do volunteer work are happier than those who do not. So is it that volunteer work creates happier people or do happier people do volunteer work?

Reverse correlations are sometimes difficult to notice. Everyone falls prey to these kinds of thinking at one time or another even the most successful scientists, business people, government officials and so on.  Critical thinking requires experience and time on task to discover additional issues. Sometimes a fresh mind is also needed, the ability to look at a problem in a different aspect.
