DAVID PIZARRO can change the way you think, and all he needs is a small vial of liquid. You simply have to smell it. The psychologist spent many weeks tracking down the perfect aroma. It had to be just right. “Not too powerful,” he explains. “And it had to smell of real farts.”
It’s no joke. Pizarro needed a suitable fart spray for an experiment to investigate whether a whiff of something disgusting can influence people’s judgements.
His experiment, together with a growing body of research, has revealed the profound power of disgust, showing that this emotion is a much more potent trigger for our behaviour and choices than we ever thought. The results play out in all sorts of unexpected areas, such as politics, the judicial system and our spending habits. The triggers also affect some people far more than others, and often without their knowledge. Disgust, once dubbed “the forgotten emotion of psychiatry”, is showing its true colours.
