Fun! What the teacher doesn't mention is that there are plenty of peer-reviewed papers in which the peers are a group that was specifically selected to support the study design and conclusions. So, just because an article is peer-reviewed and got itself published in a major journal doesn't mean we don't need to read it with a critical eye. It is also essential to determine who funded the study and what affiliations the authors have.
Totally agree but didn't want to make the post too long
Right! Perhaps a subject for another story...
