Assessing Others: Evaluating the Expertise of Humans and Computer Algorithms
Assessing Others: Evaluating the Expertise of Humans and Computer Algorithms
How do we come to recognize expertise in another person and integrate new information with our prior assessments of that person's ability? The brain mechanisms underlying these sorts of evaluations-which are relevant to how we make decisions ranging from whom to hire, whom to marry, and whom to elect to Congress-are the subject of a new study by a team of neuroscientists at the California Institute of Technology (Caltech).
