      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 …

      So they researchers looked at a small sample of people who visited a park, compared their before/after scores, and found that they were a ~tiny~ bit happier after being in the park But that's not all

      Guess who funded this research? If you guessed the CITY OF MOUNTAIN BROOKS PARKS AND RECREATION DEPARTMENT, you'd be hilariously rightpic.twitter.com/llJJ60aT63

          Anyway, they did some logistic regression to test how well time spent in park predicted wellbeing and found that 20.5 minutes was the optimal amount Ish

          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
