Summary: The longer a person hesitates before answering a question, the less sincere their response seems to others.

When people pause before replying to a question, even for just a few seconds, their answers are perceived to be less sincere and credible than if they had replied immediately, according to research.
And the longer the hesitation, the less sincere the response appears.
“Evaluating other people’s sincerity is a ubiquitous and important part of social interactions,” said lead author Ignazio Ziano, PhD, of Grenoble Ecole de Management. “Our research shows that response speed is an important cue on which people base their sincerity inferences.”
The research was published in the Journal of Personality and Social Psychology.
Researchers conducted a series of experiments involving more than 7,500 individuals from the United States, the United Kingdom and France. Participants either listened to an audio snippet, viewed a video or read an account of a person responding to a simple question (e.g., did they like a cake a friend made or had they stolen money from work). In each scenario, the response time varied from immediate to a 10-second delay. Participants then rated the sincerity of the response on a sliding scale.
Across all 14 experiments, participants consistently rated delayed responses as less sincere regardless of the question, whether it was a harmless one about cake or a more serious one about committing a crime.
A few conditions reduced this effect, the researchers found. For example, if the answer was considered socially undesirable, such as saying, “No, I don’t like it” when a friend asks if you like their cake, response speed did not seem to matter much; the answer was considered sincere whether it was fast or slow. The researchers also found that if people thought a slower response was due to mental effort (for instance, having to think back if you had stolen candy 10 years ago), response speed had a smaller effect.
The findings have wide implications, according to Ziano. “Whenever people are interacting, they are judging each other’s sincerity. These results can be applied to a wide range of interactions, going from workplace chit-chat to couples and friends bickering,” he said. “Further, in job interviews and in court hearings and trials, people are often tasked with judgments of sincerity. Here, too, response speed could play a part.”
For example, he said, imagine a hiring manager asking two job candidates, named Ann and Barb, whether they really know the programming language Javascript, as they claim. Ann says yes immediately, while Barb replies yes after three seconds.
“Our results suggest that in this situation, the hiring manager is more likely to believe Ann than Barb, and therefore more likely to hire Ann,” said Ziano. “In general, whenever there is a response that requires an answer, such as in a job interview, delayed responses can be perceived as less sincere.”
Another area where response time may be important is jury reactions to testimony in court.
“It would be unfair for the responder, such as a crime suspect, if the response delay was misattributed to thought suppression or answer fabrication when it was in fact caused by a different factor, such as simply being distracted or thoughtful,” said Ziano.
The final experiment found that explicitly instructing participants to ignore delayed response reduced, but did not completely remove, the effect of delayed response on judgment of sincerity or guilt.

“Nevertheless, our research shows that, on the whole, a fast response seems to be perceived as more sincere, while a response that is delayed for even a couple of seconds may be considered a slow lie,” said Ziano.

“Slow lies: Response delays promote perceptions of insincerity” by Ziano, I., & Wang, D. Journal of Personality and Social Psychology
Abstract
Slow lies: Response delays promote perceptions of insincerity
Evaluating other people’s sincerity is a ubiquitous and important part of social interactions. Fourteen experiments (total N = 7,565; 10 preregistered; 11 in the main article, three in the online supplemental materials; with U.S. American and British members of the public, and French students) show that response speed is an important cue on which people base their sincerity inferences. Specifically, people systematically judged slower (vs. faster) responses as less sincere for a range of scenarios from trivial daily conversations to high stakes situations such as police interrogations. Our findings suggest that this is because slower responses are perceived to be the result of the responder suppressing automatic, truthful thoughts, and fabricating a novel answer. People also seem to have a rich lay theory of response speed, which takes into account a variety of situational factors. For instance, the effect of response delay on perceived sincerity is smaller if the response is socially undesirable, or if it can be attributed to mental effort. Finally, we showed that explicit instructions to ignore response speed can reduce the effect of response speed on judgments on sincerity. Our findings not only help ascertain the role of response speed in interpersonal inference making processes, but also carry important practical implication. In particular, the present study highlights the potential effects that may be observed in judicial settings, because the response speed of innocent suspects may mislead people to judge them as insincere and hence guilty.
