Statistical Significance Explained
If you didn’t read the House of Commons Library’s statistical literacy guides recently (or you need a refresher on what, exactly, statistical significance means), then you can do much worse than student Warren Davies’ short rundown on the meaning of statistical significance: In science we’re always testing hypotheses. We never conduct a study to ‘see…

Sergey Brin’s Search for a Parkinson’s Cure
After discovering that he held the LRRK2 mutation on his twelfth chromosome (indicating that his lifetime risk of developing Parkinson’s disease is 30-75% rather than the typical 1%), Google co-founder Sergey Brin became one of the first philanthropists to fund research into a disease based on the results of a genetic test. In Thomas Goetz’s…

Medicine, Specialism, and the Scientific Education
In the commencement speech he delivered to the graduates of Stanford’s School of Medicine earlier this year, Atul Gawande eloquently (as ever) examined the state of modern medicine (in the U.S. specifically, the world generally), the problem with specialism, and the problem of specialists trying to fit into a system not necessarily designed for it.…

Why Science Needs PR
Scientists needing to persuade society at large shouldn’t be relying on their data alone to persuade but instead should employ PR tactics, suggests Wired‘s Erin Biba (and a number of PR company employees, natch). I don’t totally agree with the idea (scientific integrity and all that jazz) but some of the thoughts/suggestions are entirely valid…

Statistical Literacy Guides
I am suitably impressed by the clarity and breadth of the House of Commons Library’s statistical literacy guide on How to spot spin and inappropriate use of statistics (pdf, via @TimHarford). A quick dig around the archives revealed a full series of statistical literacy guides (all pdf), all of which are fantastically readable, accessible and comprehensive. These…

In an article the Royal Statistical Society announced as the runner-up in their annual Awards for Statistical Excellence in Journalism, Helen Rumbelow thoroughly investigates the well-debated subject of breastfeeding. The conclusion of the piece is that much of the evidence in support of breastfeeding is massively misrepresented or inherently flawed. “The evidence to date suggests…

A History of the Climate Change Controversies
After obtaining and analysing the documents and emails from the Climate Research Unit email controversy (the so-called Climategate emails), Der Spiegel “reveals how the war between climate researchers and climate skeptics broke out, the tricks the two sides used to outmaneuver each other and how the conflict could be resolved”. The result is an exceptional and…

Fooled by Pseudoscience: A Philosophy of Science
The “huge quantities of data” collected on the subject show that the principal reason people are deceived by pseudoscientific claims and alternative therapies is not intellectual ability, but personal experience: a bad personal experience with mainstream medicine is the overwhelming reason, regardless of medical training. That’s from Ben Goldacre in an interview for The Philosophers’ Magazine…

Seven Threats to a Sustainable ‘Food Future’
In a hugely captivating and comprehensive look at the food supply chain in Britain, Jeremy Harding provides a look at “the future of food and its supply”–including food ethics, food security and the dire need for a sustainable future. Harding’s case is the most cogent I’ve read and it offers much more than a condemnation…

In Praise of Self-Tracking: The Data-Driven Life
It is a natural desire to strive for self-improvement and seek knowledge about oneself, but until recently it has been difficult or impossible to do so objectively and quantitatively. Now, through self-tracking systems and applications that are becoming prevalent in many of our lives thanks to a number of technological advances and sociological changes, we can,…
