You don't know that. The way we think changed a lot in the last 40 years. Researching the causes and dynamics of these changes are very hard to study and even harder to correlate and then much more to prove causation. We basically don't have the scientific means or theory for this type of long term changes. It could very much be that kids that grew on TV have some other thought patterns that caused the reality we live in today. It's extremely confounded on so many things. We cant really know for sure anything about it. The fact that some knowledge and intelligence is not accessible to science (today) doesn't mean it doesn't exist. Just that we don't have the tools to study it, yet.
