Imagine walking into a busy mall when someone approaches you with an open hand. “Would you have some coins to take the bus, please?” he asks. But in this case, the person is not a panhandler. The beggar is a PhD.
As part of a French study, researchers wanted to know if they could influence how much money people handed to a total stranger using just a few specially encoded words. They discovered a technique so simple and effective it doubled the amount people gave.
The turn of phrase has been shown to not only increase how much bus fare people give, but was also effective in boosting charitable donations and participation in voluntary surveys. In fact, a recent meta-analysis of 42 studies involving over 22,000 participants concluded that these few words, placed at the end of a request, are a highly-effective way to gain compliance, doubling the likelihood of people saying “yes.”
What were the magic words the researchers discovered? The phrase, “but you are free to accept or refuse.”
The “but you are free” technique demonstrates how we are more likely to be persuaded when our ability to choose is reaffirmed. The effect was observed not only during face-to-face interactions, but also over email. Though the research did not directly look at how products and services might use the technique, the study provides several practical insights for how companies can influence customer behavior.
