I read both abstracts and it sounds like those guys know what they're talking about. However, I take their findings with a certain grain of salt; i.e. they may be correct but I'm not 100% convinced. Their investigation is very esoteric; and if it were my field, I would be able to recognize the validity of their methods and assumptions; but since it is not my field of expertise, all I can recognize is that their findings rest heavily on the correctness of their methods and assumptions. If the papers were peer-reviewed, with general buy-in from the reviewers, that would make a big difference to me.

Anyway, thanks for the link. The article abstracts were very interesting and enlightening.
