Uncertain advice preferred over certain advice in decision-making, study finds.
The study looked at why people prefer uncertain advice over certain advice in decision-making situations with high uncertainty. Results from four experiments showed that when decisions are unclear, people prefer uncertain advice because they perceive the advisor to have considered alternative outcomes thoroughly. However, the positive effect of uncertain advice disappears when there are many other alternatives to consider. Additionally, factors like precision effect and perceived uniqueness do not explain the preference for uncertain advice. This research can contribute theoretically to understanding the positive effects of probabilistic predictions and uncertainty expressions, and may help in developing practical communication strategies for businesses and media. It also sets the stage for future meaningful research on probabilistic predictions and uncertain advice.
