A joint New Zealand-Canadian study has caught the eye of US news satirist Stephen Colbert - known for his concept of "truthiness".
Eryn Newman, a PhD student in Victoria's School of Psychology, along with researchers from the University of Victoria in British Columbia, looked into the "truthiness" phenomenon - the feeling that something is true without empirical evidence.
The study found people are more likely to believe a claim if it is accompanied by a picture, regardless of whether it is true.
The research has been published in Psychonomic Bulletin & Review.
Colbert, in a segment called "Who's honouring me now?" on his show The Colbert Report, described truthiness as "the truth that you feel in your gut regardless of what the facts support".
