“I agree, the world would be a better place if doctors were less enthusiastic about adopting very new drugs.”

The placebo effect is one of the most fascinating things in the whole of medicine. It’s not just about taking a pill, and your performance and your pain getting better. It’s about our beliefs and expectations. It’s about the cultural meaning of a treatment.

I spend a lot of time talking to people who disagree with me – I would go so far as to say that it’s my favourite leisure activity.

Data is the fabric of the modern world: just like we walk down pavements, so we trace routes through data, and build knowledge and products out of it.

These corporations run our culture, and they riddle it with bullshit.

If I was writing a lifestyle book it would have the same advice on every page, and you’d know it all already.

I’ve detected myself using a new rule of thumb: if you don’t link to primary sources, I just don’t trust you.

Eat lots of fruit and vegetables, and live your whole life in every way as well as you can: exercise regularly as part of your daily routine, avoid obesity, don’t drink too much, don’t smoke, and don’t get distracted from the real, basic, simple causes of ill health.

Science has authority not because of white coats or titles, but because of precision and transparency: you explain your theory, set out your evidence, and reference the studies that support your case.

Teaching needs an ecosystem that supports evidence-based practice. It will need better systems to disseminate the results of research more widely, but also a better understanding of research, so that teachers can be critical consumers of evidence.

You cannot reason people out of a position that they did not reason themselves into.
