what it claims

Consciously bringing one's attention back to the present moment, rather than letting one's mind constantly drift toward worries about the future or regrets about the past, is essential to protecting one's mental well-being and reducing stress.

holds up

The claim that attentional drift is detrimental to well-being is solidly supported.

noli's read

The claim that attentional drift is detrimental to well-being is solidly supported. A famous observational study by Killingsworth and Gilbert (published in Science in 2010) shows that our minds spend nearly 47% of their time wandering, and that this wandering is correlated with a lower level of satisfaction. Regarding the return to the present moment, a vast meta-analysis of randomized controlled trials (RCTs) conducted by Goldberg and colleagues in 2018 confirms that mindfulness-based attention regulation significantly reduces stress and repetitive negative thoughts. The fact that rumination and worry exhaust our cognitive resources is a well-documented mechanism. Nevertheless, it should be noted that mind wandering is not purely negative: observational research shows that it also fosters creativity and future planning when structured. The exaggeration here is minimal because the creator provides nuance herself by recalling the usefulness of projecting oneself, making this advice an excellent pillar of mental hygiene.

What the graded evidence says

Evidence
B
Effect
mindfulness meditation vs active control on anxiety, depression, pain, and attention (meta-analysis of RCTs) — anxiety effect size 0.38 (95% CI 0.12-0.64) at 8 weeks; depression 0.30 (0.00-0.59); pain 0.33 (0.03-0.62); low/insufficient evidence for effects on attention
Measured on
diverse adult clinical populations

What’s uncertain

Effects on stress and mood are small-to-moderate; the evidence that meditation improves attention or concentration specifically is weak. It was not better than other active treatments like exercise or therapy.
