Buzzdown, welcome to WebmasterWorld! What you're talking about is "correlation does not imply causation"
IncrediBILL noted that there seems to exist a correlation. For sites with thousands of daily visitors, the percentage differences become statistically significant. So, +1 for correlation.
About causation... That hasn't been determined yet. We're trying to establish what those causes could be.
Edit/add: some supporting evidence that seems to indicate that "less savvy users click more" CTR of AOL/organic sourced traffic is 2x that of Google/organic.
