>We have the data to show that mindfulness works

Do we? (From "Has the science of mindfulness lost its mind?" (2016))

"A recent comprehensive meta-analysis of randomised clinical trials showed that mindfulness interventions only led to moderate improvements in depression, anxiety and pain, and very small improvements in stress reduction and quality of life. There was no evidence that mindfulness had an effect on other variables, such as positive mood, attention, sleep or substance use. Further, when mindfulness was compared with other interventions, such as physical exercise or relaxation, it was not more effective."
