From the Archives: Surprise Inspires WOM
It's common knowledge that emotional marketing is good marketing. But one emotion in particular -- surprise -- is key in effective WOM campaigns, according to a 2003 pilot study in the Journal of Economic Psychology. The authors of the study, French researchers Christian Derbaix and Joelle Vanhamme, found a strong correlation between surprise, subsequent emotions and the frequency of WOM, concluding that pleasantly surprising experiences foster positive word of mouth while bad surprises foster negative word of mouth; the more intense the surprise, they add, the stronger the WOM.
