Let's start with the study: Psychologists reported 92 th volunteers that a famous person has died. In half the cases the statement was supported by a photo. And it was not a photo in the coffin or the funeral, and the usual portrait photo of the man. The researchers found that the statement of a photo caused the subjects much more confidence, although the picture itself does not prove anything.
In another case, a photograph accompanied by a statement of a general nature, such as "Macadamia evolutionarily close to the peaches." The result is the same - people who showed more photos of these plants and not question the veracity of the statement.
The study authors suggested that this effect is caused by the fact that, looking at the photos, the man is easier to imagine the object of a statement, which leads to the fact that he partially perceives this information as your own knowledge. Consequently, the credibility of the source is significantly increased.
