Revisiting the links between numeracy and decision making: Replication of Peters et al. (2006) with an extension examining confidence
Assessing the replicability of specific links between numeracy and decision-makingRecommended by Chris Chambers based on reviews by Daniel Ansari and Elena Rusconi
Numeracy – the ability to understand and work with numbers – is associated with a wide range of social and health-related outcomes, including socioeconomic status, employment, literacy, reasoning, and life satisfaction. A substantial body of evidence has also shown links between numeracy and decision-making, prompting the question of how it relates to finer-grained measures of reasoning, judgment and affect/emotion.
In the current study, Zhu and Feldman propose to replicate four influential experiments from a study by Peters et al. (2006), which demonstrated links between numeracy and performance on a variety of decision-making tasks, including attribute framing, frequency-percentage framing, susceptibility to affective influences, and various cognitive biases. The authors also propose several extended questions, including refinements of the original hypotheses and an examination of the relationship between numeracy and confidence in numeric judgments (subjective numeracy).
The Stage 1 manuscript was evaluated over one round of in-depth review. Based on detailed responses to the reviewers' comments, the recommender judged that the manuscript met the Stage 1 criteria and therefore awarded in-principle acceptance (IPA).
