Again, you have a hypothesis that sounds very plausible, but because it does sound so plausible, I'm instantly suspicious of it. Plausible things often turn out to be false.

Is there any quantitative test you can propose, or an experiment you could run, that would give you a number between 0 and 1, representing the probability of your hypothesis being true ? If the answer is "yes", then perhaps someone had already done the research ? If the answer is "no", then IMO it's not thinking about.
