The average adult in the US reads at an 8th grade level and news papers are written at the 4th grade level (I think they still are, there was talk of dropping them to the 3rd grade level).

Technically correct? More than that, but Rumsfeld is known to talk a bit above the crowd. Remember this quote?

"Reports that say something hasn't happened are always interesting to me, because as we know, there are known knowns; there are things we know we know. We also know there are known unknowns; that is to say we know there are some things we do not know. But there are also unknown unknowns -- the ones we don't know we don't know."

It makes perfect sense to any one familiar with higher level philosophy, logic, mathematics or even database design. He'll never live it down, though.

Peace.
