From my perspective, we as skeptics have identified a problem, many people are not rational thinkers. If we are to ever change that fact we need to do a better job of assessing the root causes.
I am not familiar with where Dawkins was going with this. I am familiar with how reporters get it wrong. If I were to speculate, I'd say Dawkins was correctly looking at potential beginnings of irrational thinking. That in turn might lead to means of changing the irrational thinkers to rational thinkers.
Unless I see more evidence Dawkins was on to something else, that is where the evidence leads me in this case. And that is a reasonable line of investigation for Dawkins to be interested in.
