The same fundamental platform that allows Schrödinger’s cat to be both alive and dead, and also means two particles can “speak to each other” even across a galaxy’s distance, could help to explain perhaps the most mysterious phenomena: human behavior.
Quantum physics and human psychology may seem completely unrelated, but some scientists think the two fields overlap in interesting ways. Both disciplines attempt to predict how unruly systems might behave in the future. The difference is that one field aims to understand the fundamental nature of physical particles, while the other attempts to explain human nature — along with its inherent fallacies.
“Cognitive scientists found that there are many ‘irrational’ human behaviors,” Xiaochu Zhang, a biophysicist and neuroscientist at the University of Science and Technology of China in Hefei, told Live Science in an email. Classical theories of decision-making attempt to predict what choice a person will make given certain parameters, but fallible humans don’t always behave as expected. Recent research suggests that these lapses in logic “can be well explained by quantum probability theory,” Zhang said.
