Dean Burnett writes a column in Guardian, sometimes about science but more entertainingly on pseudo-, wannabe-, and not-actually- science. Most of the time this is good BS-shovelling fun and I recommend it. Unfortunately today we get some ill-considered overreach under the guise of shovelling.
The subject is a silly equation purporting to define how depressing any day of the year is, and thereby to identify the most depressing one. It is sufficiently silly that it doesn’t deserve a link, has no redeeming features and if you’ve not read it yet you’re just lucky. He’s right. It is nonsense.
The arguments are more interesting, if a bit alarming. To put it bluntly: if they were sound they would sink all regression models about any social issue of any interest to anybody ever.
