You can try this yourself. A google of the phrase “right-wing think-tank” returns 86,600 hits while a google of the phrase “left-wing think-tank” returns only 16,200. What do you suppose we should conclude from this? That there are approximately five times more right-wing think tanks out there than left-wing ones, or that the right-wing ones have five times more fingers wiggling at them? Whichever the case, I demand more balance!
