You are browsing a website to decide what to boots to buy. You see a pair that looks good and then you scroll down to see the ratings. Many people have rated the boots highly, but a few say the boots are cheaply made and uncomfortable. What will you do? Will you buy the boots or not?
Uncertainty tips the scale
In my book, Neuro Web Design: What makes them click? I have a chapter on this topic. The tendency to look to others to decide what to do is called social validation. Research on social validation shows that it is when we are uncertain about what to do that we will most look to others to decide.
Is the smoke dangerous? — There have been many studies about social validation. Latane and Darley conducted a series of studies where they would set up ambiguous situations to see if people were affected by what others around them were or were not doing. For example, they would bring someone into a room, supposedly to fill out a survey on creativity. In the room would be one or more other people who were pretending they were also participants in the creativity study, but who were really part of the experiment. Sometimes there would be one other person in the room, sometimes two others or more. While everyone is filling out their creativity survey, smoke starts coming into the room from an air vent. The researchers were interested in seeing if the participant would leave the room, or go tell someone about the smoke, or just ignore it. It wasn’t clear what the smoke was, or if it was dangerous. So it was an ambiguous situation.
Only if others think it is — Whether or not the participant left the room and/or went to get help, or whether they stayed there and kept filling out the form, depended on the behavior of the other people in the room, as well as how many other people there were. The more people in the room, and the more the others ignored the smoke, the more the participant was likely to also ignore the smoke. If the participant was alone they would go leave the room and go to notify someone. But if there were others in the room not reacting, then the participant would also not react.
Testimonials and ratings are powerful — Online, social validation is most in evidence with ratings and reviews. When we are unsure about what to do we look to testimonials, ratings, and reviews to tell us how to behave. The most powerful ratings and reviews:
- Include information about the person writing the review – a mini “persona”. This is effective because the person reading the review will give more credence to a review written by someone who is like them.
- Tell a story about the product or service. Because stories “talk” to our mid, or emotional brain, they are very powerful.
- Ratings from people like us are more powerful than ratings from “experts”. I wrote another blog post on research by Chen on ratings and reviews at a book web site that studied these different types of ratings. Ratings from other readers were more powerful in influencing behavior than ratings from experts or from the website itself.
Although people don’t like to admit that they are easily influenced by others, the truth is that they are. What do you think? Do you try to resist the impact others have on your decisions?
