“Most of our measures of a key cognitive process don't agree”

Key points

• Nature published a study showing three common reappraisal measures don't align.
• Researchers analyzed trait questionnaires, task ratings, and amygdala down-regulation via fMRI.
• Effect sizes were small; detecting them would require over a thousand participants.
• Differences between in-the-moment data and long-term questionnaires reduce comparability.
• The paper calls for new methods and cautious interpretation of brain-region claims.
