Welcome to my website. My name is Chris Blunt. I am a philosopher of medicine, and a fellow at the London School of Economics. I work on Evidence-Based Medicine, hierarchies of evidence, and other problems related to evidence and ethics in biomedical research, medical genomics and complementary & alternative medicine.

I received my PhD from LSE in 2016, with a thesis focused on ‘Hierarchies of Evidence’, which you can read here. Hierarchies of Evidence are a popular tool for appraising evidence used in medical practice, and a common way of teaching evidence appraisal to medical students. I maintain the largest database of such hierarchies online. If you know of a hierarchy which is not listed here, please do contact me.
