3) Correlative-causative fallacy - a fancy-arse way of saying that things that co-occur may do so because of a third unrelated factor.

Now, cast your stupid fat eyes over this.

Of course, you can't tell exactly how the research was conducted without reading it and journalism concerning science is almost always hammered shit (a source of unending frustration to me), but which of the above problems does the article suggest this study committed?

Don't forget in vivo or in vitro--or however the hell you spell those. It's very hard to study shit. That article sounds good so far, but I try to be suspicious of everything. I'll wait till valentine's day to say anything worth my while......
