A single training session using a tool designed to address interpretation bias in medical students was effective in reducing overall bias, suggesting potential applications in addressing health disparities. The tool, cognitive bias modification for stereotype (CBM-S), uses an implicit learning task to create a less biased interpretation of Māori patients in common health scenarios. Following CBM-S training, stereotype interpretation bias scores were reduced over time, as well as post-training stereotype bias scores after adjustment for baseline bias scores.
