The Centre for Evidence-Based Medicine (CEBM) has decamped to somewhere near Warwick for two days to update the Catalogue of Bias.

For those not familiar with the Catalogue of Bias, it aims to better understand the persistent presence, diversity, and impact of biases. The Catalogue stems from original work by David Sackett.

Sackett recognised the importance of bias in research. His 1979 paper “Bias in Analytic Research”, published in the Journal of Chronic Diseases. He proposed that the continued development of an annotated catalogue of bias be a research priority, stating that each citation should include a useful definition, a referenced example illustrating the magnitude and direction of its effects, and a description of the appropriate preventive measures, if any.
