Here is an excerpt:
Their work suggests that thinking in a quantum-like way¬--essentially not following a conventional approach based on classical probability theory--enables humans to make important decisions in the face of uncertainty, and lets us confront complex questions despite our limited mental resources.
When researchers try to study human behavior using only classical mathematical models of rationality, some aspects of human behavior do not compute. From the classical point of view, those behaviors seem irrational, Wang explained.
For instance, scientists have long known that the order in which questions are asked on a survey can change how people respond--an effect previously thought to be due to vaguely labeled effects, such as "carry-over effects" and "anchoring and adjustment," or noise in the data. Survey organizations normally change the order of questions between respondents, hoping to cancel out this effect. But in the Proceedings of the National Academy of Sciences last year, Wang and collaborators demonstrated that the effect can be precisely predicted and explained by a quantum-like aspect of people's behavior.
