The Numerical Precision Effect: How Precision of Attribute Information Affects Adoption of Technology Products
研究发现，当技术产品的某个属性对消费者来说不熟悉时，提供精确的数字（如折叠次数54,986次）比近似数字（55,000次）更能提升购买意愿，因为精确性让人感觉该属性经过精细校准，从而增强对技术的可靠性感知。
This research examines the influence of numerical precision on consumer evaluations of technology products. We posit that when an attribute of a technology product is unfamiliar (vs. familiar), numerical precision of the attribute information (e.g., Galaxy Fold’s folding durability of 54,986 times vs. 55,000 times) increases the willingness to purchase the product. This occurs because numerical precision induces inferences that the attribute is highly calibrated, which, in turn, increases perceived reliability of the technology. However, this precision effect attenuates when the unfamiliar attribute is non‐performance‐related (vs. performance‐related). Four studies using a variety of products and operationalizations of both numerical precision and attribute calibration perception provide converging evidence for the proposed effect and underlying mechanism. Theoretical and managerial implications are discussed.
