People often say that quantum physics is weird because it doesn’t seem rational. But of course, if you think about it, quantum physics is actually perfectly rational, if you understand the math. It’s people who typically seem irrational.

In fact, some psychologists have spent their careers making fun of people for irrational choices when presented with artificial situations amenable to statistical analysis. Making allowances for sometimes shaky methodology, there really are cases where people make choices that don’t seem to make much sense.

In 1929, Bohr noted that quantum physics refuted the view that analyzing brain processes could “reveal a causal chain that formed a unique representation of the emotional mental experience.” But in quantum physics, Bohr emphasized, an observer inevitably interacted with whatever was being observed, so “any attempt to acquire a knowledge of such [mental] processes involves a fundamentally uncontrollable interference with their course.”

“If we replace ‘human judgments’ with ‘physical measurements,’” Wang and colleagues write, “and replace ‘cognitive system’ with ‘physical system,’ then these are exactly the same reasons that led physicists to develop quantum theory in the first place.”
