Study proposes a new bias: The tendency to assume one has adequate information to make a decision

New experimental data support the idea that people tend to assume the information they have is adequate to comprehend a given situation, without considering that they might be lacking key information. Hunter Gehlbach of Johns Hopkins University and colleagues present these findings in the open-access journal PLOS ONE on October 9, 2024.

When navigating alternative perspectives, people may demonstrate psychological biases that influence their ability to understand others' viewpoints. For instance, in the bias of naive realism, people presume their own subjective perspective is objective truth.
