The Short Version
The scientific evidence does not support the broad claim that women are more emotionally driven than men in decision-making. Peer-reviewed meta-analyses and empirical studies show that sex differences in emotional influence on decisions are small, task-specific, and inconsistent in direction — with some research finding men more susceptible to emotional spillover in financial decisions. The claim relies on conflating emotional sensitivity or neural activation with emotion-dominated choices, a logical leap that neuroscience research explicitly cautions against.
