One Persuasion Technique Everyone Should Know

Which persuasion technique, based on psychological research, is most practical, can easily be used by anyone in almost any circumstances and has been consistently shown to work? The PSYBlog answers:

The answer is: the ‘But You Are Free’ technique. This simple approach is all about reaffirming people’s freedom to choose. When you ask someone to do something, you add on the sentiment that they are free to choose.

By reaffirming their freedom you are indirectly saying to them: I am not threatening your right to say no. You have a free choice.

A recent review of the 42 psychology studies carried out on this technique has shown that it is surprisingly effective given how simple it is (Carpenter, 2013). All in all, over 22,000 people have been tested by researchers. Across all the studies it was found to double the chances that someone would say ‘yes’ to the request.

People have been shown to donate more to good causes, agree more readily to a survey and give more to someone asking for a bus fare home.

The exact words used are not especially important. The studies have shown that using the phrase “But obviously do not feel obliged,” worked just as well as “but you are free”.

What is important is that the request is made face-to-face: the power of the technique drops off otherwise. Even over email, though, it does still have an effect, although it is somewhat reduced.

Somewhat ironically, respecting people’s autonomy can make them more open to persuasion.
