Article Correctness Is Author's Responsibility: How we make decisions depends on how uncertain we are

A new study on how we use reward information for making choices shows how humans and monkeys adopt their decision-making strategies depending on the uncertainty of information present. The findings challenge one of the most fundamental assumptions in economics, neuroeconomics and choice theory that decision-makers typically evaluate risky options in a multiplicative way when in fact this only applies in a limited case when information about both the magnitude and probability of the reward are known.
