Truth & Photos

Ever been in a position where you were designing a brochure and wondered whether you should put in a particular photo? You might have decided against it because you felt a generic photo might look bland or you had trouble getting a photo that fitted well with the point you were trying to make.

It turns out that the choice of photo might not really matter that much, the important thing is to have a photo and almost any kind will do.

The BPS reports on a study involving New Zealand and Canadian students which found that including a photo with a statement made us more inclined to believe a statement accompanying the photo was true. The participants were given a series of statements saying if well known and obscure celebrities were either dead or alive. As fast as they could, without compromising their accuracy, the students had to say whether each statement was true or not. Crucially, half the statements were accompanied by a photo of the relevant celebrity and half weren't.

The statements with the photo were rated more likely to be true. As the researchers put it, the presence of the photo seemed to "inflate truthiness".

Another study with 70 New Zealand undergrads was similar but this time uninformative photos accompanied obscure general knowledge facts. For example, "Macademia nuts are in the same evolutionary family as peaches" was presented alongside a photo of macadamia nuts that provided no clues as to the veracity of the statement. The same effect was found - the students were more likely to wager that a fact was true when it was accompanied by an uninformative photo

So if you are designing a brochure and have testimonials that say your software is best of breed or your customer service has an approval rating of 99% or your deliveries are always on time, include a photo of a PC, Customer Service Agent or Delivery Guy. Generic non-descript photos are no problem, it need not be actual people or items. People will be more likely to rate your claim as true.

The same could be true for how you design websites, how politicians design election material or how you organise your eBay shop or any other on-line profile you may have. Any kind of photo will "inflate” the "truthiness" of your proposition. Guess I should have included a photo as part of this post.
