Did you know that the information provided by a salesperson wearing a red sweater seems more accurate than information provided by a shop assistant in blue? Or that women are more likely to be interested in a service they hear advertised by a man with a creaky voice than a woman with a creaky voice? (Men don’t seem so bothered by voice quality). What about that if you’re someone who finds maths tricky, you’ll find it easier to compare prices when there is slow tempo classical music playing in the background?
