I've been reading up on journal articles on birth order in preparation for a DPhil paper. I ran across two (published!) papers that both committed deep and unforgivable sins. See if you can spot them.
First up, one paper (I'll omit titles and author names) began with citing a quote relevant to birth order:

where the parameter of interest was, of course, beta.
