On Tuesday 12th of July, the Guardian published details of a scientific study that raised important questions about the use of mindfulness in secondary schools. This article discussed a My Resilience in Adolescence (Myriad) trial of the benefits of School-based mindfulness training (SBMT), a major research effort involving 8,376 students in the 11–13 age range across different sites. The study had robust clinical methodologies, and it’s perhaps the most reliable SBMT investigation published to date. However, the Guardian headline claimed that ‘SBMT does not improve mental health’. But the original paper offers even more challenging findings:
SBMT as delivered in this trial is not indicated as a universal intervention. Moreover, it may be contraindicated for students with existing/emerging mental health symptoms.
Clinical implications:
Universal SBMT is not recommended in this format in early adolescence. Future research should explore social−emotional learning programmes adapted to the unique needs of young people.1

This is not the first scientific study of SBMT; the Guardian describes earlier research as ‘mixed’. Taken together, the earlier and current findings for the benefits of SBMT reflect an established pattern in the science of mindfulness that is frequently ignored, a tension between tentative early-stage studies and more robust scientific evidence. Demonstrating positive preliminary effects has never been a problem in the scientific engagement with meditation. In the first twenty years of mindfulness research, spectacular claims were frequently made about the benefits of meditating, but few of those preliminary findings were confirmed by large-scale randomised controlled trials (RCTs).
Since the 1980s, scientists have warned that preliminary uncontrolled, unrandomised, unreplicated mindfulness studies must be treated cautiously. And strategic reviews of mindfulness research frequently found initial claims to be unreliable on both theoretical and methodological grounds. But these evidence-based problems have had little effect on the scientific and social policy enthusiasm for mindfulness. This binary of positive preliminary studies challenged by more scientifically reliable evidence continues to this day. And traces of it can be seen in other forms of medicalised meditation. The problem illustrated by this Myriad trial of SBMT is simply the latest example of the paradoxical nature of mindfulness, an intervention frequently more promising than proven.
The rationales underpinning many mindfulness clinical studies have provoked concerns. One of the harshest from Nicholas Van Dam and 14 co-authors who, in 2018, claimed that methodological weaknesses and unreliable reporting of initial claims might lead mindfulness consumers to be harmed.2 As a meditator and meditation scientist, nobody wants to see the success of medicalised meditation methods more that I. But there is evidence that we are in an epistemological crisis in meditation research. A state confirmed by my current project to write a scientific history of mindfulness. However, rather than a simple description, my work has identified the causes of the crisis and, thus, the possible solutions. But given the current trajectory of mindfulness research, there is little hope of significant change until the mindfulness community confronts the systemic research problem in this field present since the 1980s.
