There is this peculiar blind spot in the culture of academic medicine around whether withholding trial results is research misconduct. People who work in any industry can reinforce each others' ideas about what is okay.

And if, by the end [of this book], you reckon you might still disagree with me, then I offer you this: you'll still be wrong, but you'll be wrong with a lot more panache and flair than you could possibly manage right now.

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.

As it is a major component of blood, water is vital for transporting oxygen to the brain. Heaven forbid that your blood should dry out.

Real science is all about critically appraising the evidence for somebody else's position.

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.

Yes. I'm a doctor, an epidemiologist, and lots of my professional colleagues flip back and forth between industry and medical roles. I know them they are not bad people. But it is possible for good people in bad systems to do things that inflict enormous harm.

Children can be disgusting, and often they can develop extraordinary talents, but I’m yet to meet any child who can stimulate his carotid arteries inside his ribcage.

Amazing things happen when you pull individual pieces of information together into larger linked datasets: meaning emerges, as you produce facts from figures.

I write about misuses of evidence in plenty of different spheres: scaremongering journalists, obvious quacks and naturopaths, and flaws in the way that evidence is used in mainstream academia, medicine and in (government) policy. One of the things I always found interesting is the same tricks are used to distort medicine in all of those domains.

Transparency and detail are everything in science.

There are many differences between medicine and teaching, but they have much in common. Both involve craft and personal expertise, learned through experience but both can be informed by the experience of others.

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

If you put me in charge of the medical research budget, I would cancel all primary research, I would cancel all new trials, for just one year, and I would spend the money exclusively on making sure that we make the best possible use of the clinical evidence that we already have.

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.

Homeopathy pills are, after all, empty little sugar pills which seem to work, and so they embody [..] how we can be misled into thinking that any intervention is more effective than it really is.
