Research from the University of Bologna suggests that poor decision-making and risky behavior are linked to how the brain responds to biological cues. The study identified two types of individuals: sign-trackers, who are drawn to reward cues and update beliefs slowly, leading to biased choices, and goal-trackers, who focus directly on rewards. This research utilized eye-tracking and computational modeling to understand how these cue-driven behaviors can result in consistently poor and inflexible decisions.
