In the past, [medicalization]has been portrayed as something that doctors inflict on a passive and un-suspecting world - an expansion of the Medical Empire. But in reality, it seems that these reductionist bio-medical stories can appeal to us all, because complex problems often have depressingly-complex causes, and the solutions can be taxing, and unsatisfactory.

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.

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.

Most bloggers have no institutional credibility, and so they must build it, by linking transparently, and allowing you to easily double check their work. But more than anything, because linking sources is such an easy thing to do, and the motivations for avoiding links are so dubious, I've detected myself using a new rule of thumb: if you don't link to primary sources, I just don't trust you.

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.

I'd like to submit to Bad Science my teacher who gave us a handout which says that 'Water is best absorbed by the body when provided in frequent small amounts.' What I want to know is this. If I drink too much in one go, will it leak out off my arsehole instead? Thank you. Anton.

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.
