The effect of source expertise on the persuasiveness and sharing of health information on social media
People increasingly rely on social media for health information, despite substantial variability in information quality. We conducted a systematic review and meta-analysis examining whether people are sensitive to source expertise when evaluating and sharing online health claims, and if this depends on whether the source is an individual expert (e.g., a physician) or an expert group (e.g., a health organisation). Three searches across four databa…
Truth over falsehood
The English poet John Milton portrayed truth as a powerful warrior capable of defeating falsehood in open combat. The spread of false information online suggests otherwise. Here, we test the persuasive power and transmission potential of true versus false messages in a controlled experimental setting, free from the effects of social media algorithms and bot amplification. Across four experiments (combined N = 4,607), we tested how perceived verac…
Changing your mind about the data
When people use samples of evidence to make inferences, they consider both the sample contents and how the sample was generated ("sampling assumptions"). The current studies examined whether people can update their sampling assumptions - whether they can revise a belief about sample generation that is discovered to be incorrect, and reinterpret old data in light of the new belief. We used a property induction task where learners saw a sample of i…
Sampling in Judgment and Decision Making
Sampling approaches to judgment and decision making are distinct from traditional accounts in psychology and neuroscience. While these traditional accounts focus on limitations of the human mind as a major source of bounded rationality, the sampling approach originates in a broader cognitive-ecological perspective. It starts from the fundamental assumption that in order to understand intra-psychic cognitive processes one first has to understand t…
Social meta-inference and the evidentiary value of consensus
Reasoning beyond available data is a ubiquitous feature of humancognition. But while the availability of first-hand data typically diminishesas the concepts we reason about become more complex, our ability to drawinferences seems not to. We may offset the sparsity of direct evidence byobserving the statements of others, but such social meta-inference comes withchallenges of its own. The strength of socially-provided evidence depends onmultiple fa…
