Precision is Equated with Credibility and Accuracy

In a study conducted at Rutgers University, it was found that claims presented with precise numbers are perceived as more credible and accurate compared to claims presented with rounded numbers. The association between precision and credibility stems from the tendency of knowledgeable individuals to provide precise information, while those who are unsure tend to speak in generalities. This association leads people to trust precise claims more and view them as truthful, while viewing vague claims as uncertain. This association forms a simple yet powerful heuristic that influences people's judgments and decision-making.
