I could provide you with a link, but you'd be asked to sign in with a student account. Considering it's unlikely we attend the same university, a link would be useless. I provided the titles of the articles somewhere in the comments below. I realize we are accustomed to being able to "link" references, but quality academic journals are not usually available to the public which is unfortunate. Luckily, google scholar is helping provide quality research to the masses but for the time being, I use my university's research database for my sources. Hopefully with the implementation and expansion of google scholar, we'll be able to avoid unverifiable bullshit making it's way into mainstream news.
