Want to convince someone to do something? A new University of Michigan study has some intriguing insights drawn from how we speak.
The study, presented May 14 at the annual meeting of the American Association for Public Opinion Research, examines how various speech characteristics influence people’s decisions to participate in telephone surveys. But its findings have implications for many other situations, from closing sales to swaying voters and getting stubborn spouses to see things your way.
“Interviewers who spoke moderately fast, at a rate of about 3.5 words per second, were much more successful at getting people to agree than either interviewers who talked very fast or very slowly,” said Jose Benki, a research investigator at the U-M Institute for Social Research (ISR).
“When people are speaking, they naturally pause about 4 or 5 times a minute,” Benki said. “These pauses might be silent, or filled, but that rate seems to sound the most natural in this context. If interviewers made no pauses at all, they had the lowest success rates getting people to agree to do the survey. We think that’s because they sound too scripted.
“People who pause too much are seen as disfluent. But it was interesting that even the most disfluent interviewers had higher success rates than those who were perfectly fluent.”
