How Warm-Glow Alters the Usability of Technology

TL;DR

This study investigates how intrinsic and extrinsic warm glow shape perceived usability across ISO 9241-11 dimensions (effectiveness, efficiency, satisfaction) using a vignette-based experiment and validated scales. It finds intrinsic warm glow enhances all three usability dimensions, while extrinsic warm glow selectively boosts effectiveness and satisfaction, with a notable interaction yielding the largest gains in effectiveness. Robust MANOVA and univariate analyses corroborate these effects. The results suggest design strategies that evoke warm glow can meaningfully alter usability judgments, informing value-sensitive and emotionally aware UI design.

Abstract

As technology increasingly aligns with users' personal values, traditional models of usability, focused on functionality and specifically effectiveness, efficiency, and satisfaction, may not fully capture how people perceive and evaluate it. This study investigates how the warm-glow phenomenon, the positive feeling associated with doing good, shapes perceived usability. An experimental approach was taken in which participants evaluated a hypothetical technology under conditions designed to evoke either the intrinsic (i.e., personal fulfillment) or extrinsic (i.e., social recognition) dimensions of warm-glow. A Multivariate Analysis of Variance as well as subsequent follow-up analyses revealed that intrinsic warm-glow significantly enhances all dimensions of perceived usability, while extrinsic warm-glow selectively influences perceived effectiveness and satisfaction. These findings suggest that perceptions of usability extend beyond functionality and are shaped by how technology resonates with users' broader sense of purpose. We conclude by proposing that designers consider incorporating warm-glow into technology as a strategic design decision.
