A team of Toronto researchers has found that even incidental and unconscious exposure to the fast-food symbols that are all around us makes people feel time-stressed and impatient in settings far outside the eating domain. They prefer time-saving products. Such exposure speeds up the rate at which they read, even when under no time pressure, as one marker of a sense of added time urgency.
Most striking of all, just a glimpse of the golden arches changes our psychology so that people become impatient about financial decisions - they wind up unwilling to postpone immediate gain for future rewards, so they sacrifice savings, against their own economic interest...
[Researcher Sanford DeVoe] surveyed 400 US adults to see how often they are exposed to fast-food symbols in the [...] real world and whether it affects their savings rates. He was "stunned to see a robust correlation."
