[Neuroscientists] haven't found a ‘buy’ button inside the brain, we can't tell whether someone is lying or in love just by looking at their brain scans, and we can't turn sinners into saints with hormones.

Crockett is pushing back against “neurohype”: the tendency to treat brain images and neurochemical findings as if they yield simple, decisive explanations of complex human states. By listing what neuroscientists cannot do—locate a literal consumer “buy button,” read deception or love straight off a scan, or morally “fix” people with hormones—she underscores the limits of current methods and the gap between laboratory effects and real-world prediction or control. The quote also cautions against reductionism in ethics and public policy: moral character and social behavior are not straightforwardly programmable biological variables, and claims of neuroscientific certainty should be met with skepticism.
