I love Science. I love reading about science, I love doing science and I love thinking about how science can be applied to helping patients. But what I really love about science are the arguments! It is good and proper that in science ideas are debated, views challenged and criticisms aired, so when an article appeared looking at the science of scientific arguments I couldn’t resist having a read. Serge Galam from the fabulously named Centre de Recherche in Epistemologie Appliquee used a probabilistic modelling technique to explore the factors that may determine the outcome of public scientific debates. It is all fairly complicated, but basically he models agents as either inflexibles (those who are convinced of a position) or floaters (those who are open to different positions), and the results suggests that winning the debate is about increasing the proportion of people with inflexible attitudes on your side. To do this it seems that the best approach is to overstate and exaggerate the validity of your claims!! The conclusion is enough to make you weep, “to adopt a fair discourse is a definite lose-out strategy to promote a cause in a public debate. On this basis one could conclude that to adopt a cynical behaviour is the obliged path to win a public debate”.

Depressing I know, and more so when you think of the clinical implications. Patient education is rightly seen as an important part of managing long standing pain problems and it is important to realise that many of the things we might wish to inform patients about are being hotly debated in the public arena – look at the media coverage that surrounded recent studies on acupuncture or the publication of the NICE guidelines for LBP and chronic fatigue syndrome.  The information patients have access to in the popular press and online is pretty much always of the overstated and exaggerated variety, and I don’t know about you, but when explaining things to patients I try to be balanced, considered and conservative in my interpretation of the literature, the very model of the ‘lose-out strategy’, so looks like I am destined to fail. Science does deliver up some dilemmas – maybe we all need to have an argument about how to best deal with this!
