Want to convince with your gift of gab? Sales people are hip to the tricks, stating everything as a question and doing more listening than yapping. But a recent study found more subtle ways to persuade.
Scientists had 100 interviewers make calls attempting to convince responders to take a survey. They then analyzed recordings for the interviewers’ speed, pitch and fluency. What emerged were specifics that succeeded in convincing people to take the survey.
Talkers at this speed, “a nice comfy pace,” were much more successful than “a languid pace” and these talkers “boy, I’m really hopped up.” So there's a “just right” speed and it’s about three-and-a-half words per second.
Surprisingly varied pitch made no difference. So “this is really interesting” was just as convincing as “this is really interesting!”
People who pause often are typically seen as awkward but scientists found even big pausers still beat out anyone who was perfectly fluent. So “this’ll…just take…a minute” was always more successful than “this’ll just take a minute.” The research was presented at the annual meeting of the American Association for Public Opinion Research.
