[[Studies are going to be confounded by the allegiance of the researcher. When researchers who don’t believe something discover it, that’s when it’s worth looking into.

He sent one laboratory a box of rats saying they were specially bred to be ultra-intelligent, and another lab a box of (identical) rats saying they were specially bred to be slow and dumb.

The Healing Potential of Turning Vacant Lots Green
"A total of 347 randomly chosen residents living near those lots were surveyed 18 months before the intervention and 18 months after, and asked to rate how often they felt things like anxiety, hopelessness, worthlessness, and depression—based on a tool for screening the prevalence of serious mental illness in a community. None were told the survey had anything to do with the revitalization of vacant lots. What they found was that in neighborhoods below the poverty line, greening interventions decreased residents’ feelings of depression by more than 68 percent."
