This is SPECTACULAR* The "new study"? It was a before/after survey of 94 people who visited a park. Being in the park resulted in a ~1 point increase in a 55-point scale of happiness *ly badhttps://twitter.com/MailOnline/status/1102403559830757376 …

What they actually found was that, using their ROC, at 20.5 minutes, the sensitivity and specificity were 89% and 44% respectively, which is, uh, pretty much useless in terms of predictionpic.twitter.com/sHl44FSmF9

This research has been picked up a lot - Altmetric score of 224! - but seriously, you can't take much away from a 94-person survey of people who use parks that doesn't even have a control group

A more honest headline would be "People who spend time in parks improve wellbeing by 2% on average, although half have no improvement or even get worse so it's questionable whether that means much at all more research is needed"

To be fair here, I would guess that parks do improve subjective wellbeing - I mean, I doubt that they make it worse, at least - but I don't think this study methodology can really say much about that question, except that more research is needed

As another side note, this sounds like super fun for the research assistants working on the project
