Hotshot. A supplement scam with a difference?

October 25th, 2016 · 6 Comments

Jump to follow-up
The "supplement" industry is a scam that dwarfs all other forms of alternative medicine. Sales are worth over $100 billion a year, a staggering sum. But the claims they make are largely untrue: plain fraudulent. Although the industry’s advertisements like to claim "naturalness". in fact most of the synthetic vitamins are manufactured by […]

Food the Forgotten Medicine: More bait and switch from the “College of Medicine”

August 21st, 2016 · 16 Comments

‘We know little about the effect of diet on health. That’s why so much is written about it’. That is the title of a post in which I advocate the view put by John Ioannidis that remarkably little is known about the health effects if individual nutrients. That ignorance has given rise to […]

Cupping: bruises for the gullible, and other myths in sport

August 10th, 2016 · 1 Comment

This is my version of a post which I was asked to write for the Independent. It’s been published, though so many changes were made by the editor that I’m posting the original here (below).
Superstition is rife in all sports. Mostly it does no harm, and it might even have a placebo effect […]

NICE rejects acupuncture for low back pain

March 24th, 2016 · 4 Comments

Of all types of alternative medicine, acupuncture is the one that has received the most approval from regular medicine. The benefit of that is that it’s been tested more thoroughly than most others. The result is now clear. It doesn’t work. See the evidence in Acupuncture is a theatrical placebo.
This blog has documented many cases […]

Statistics and the law: the prosecutor’s fallacy

March 22nd, 2016 · 7 Comments

This post arose from a recent meeting at the Royal Society. It was organised by Julie Maxton to discuss the application of statistical methods to legal problems. I found myself sitting next to an Appeal Court Judge who wanted more explanation of the ideas. Here it is.
Some preliminaries

Placebo effects are weak: regression to the mean is the main reason ineffective treatments appear to work

December 11th, 2015 · 22 Comments

Jump to follow-up

“Statistical regression to the mean predicts that patients selected for abnormalcy will, on the average, tend to improve. We argue that most improvements attributed to the placebo effect are actually instances of statistical regression.”
“Thus, we urge caution in interpreting patient improvements as causal effects of our actions and should avoid the conceit of […]

How long until the next bomb? Why there’s no reason to think that nuclear deterrence works

October 24th, 2015 · 4 Comments

Every day one sees politicians on TV assuring us that nuclear deterrence works because there no nuclear weapon has been exploded in anger since 1945. They clearly have no understanding of statistics.
With a few plausible assumptions, we can easily calculate that the time until the next bomb explodes could be as little as 20 years. […]

He should be remembered, in the hope that some good can come from his death.

There are powerful currents whipping up the metric tide. The HEFCE metrics report

July 9th, 2015 · 3 Comments

This is very quick synopsis of the 500 pages of a report on the use of metrics in the assessment of research. It’s by far the most thorough bit of work I’ve seen on the topic. It was written by a group, chaired by James Wilsdon, to investigate the possible role of metrics […]

Are women still at a disadvantage in science?

June 15th, 2015 · 20 Comments

Jump to follow-up
There can be no doubt that the situation for women has improved hugely since I started at UCL, 50 years ago. At that time women were not allowed in the senior common room. It’s improved even more since the 1930s (read about the attitude of the great statistician, Ronald Fisher, to Florence Nightinglale […]
