Intense and long-lasting is just as important as good or bad

It is not scientifically sound to narrow down the problem with comics to whether the influence of comic books is just "good" or "bad." That cannot be a sound starting-point. The question is, do they have a discernible influence, and if they have how does it work, how intense and long-lasting is it, and in what fields and regions of the child's mind does it manifest itself.

I know what I'm talking about because his is exactly how I started.
