Whenever you read the results of the study, check out a few things…
-Sample size: is 87 people enough to make such a broad statement?
-Randomization: how were these respondents collected? Whoever wanted to sign up? Asking every third person who entered a certain building?
-Independence: Are the results independent? Since all of them were collected from a single city, this is highly doubtful, and certainly not representative of the larger population.
-Questions: All the article says is “subjects were asked to fill out a questionnaire for depression, anxiety, and burnout. All of these things are highly subjective, and if the questions were like “How depressed do you feel, on a scale of 1 – 10″ then it is even more hazy.
Get me a study with 1,000 or 2,000 randomly selected individuals, then we might have results that actually mean something.
