It does seem like a very simple study, that we would have guessed the results. Seems like a study like this would be to help facilitate laws or actions rather than finding the really important answers you are suggesting. I hope one day we come up with a model to fund research for the people, and not wait for larger organizations to fund, typically for selfish reasons. I think if we could find this model science will not only catch up, but trail-blaze new findings.
