Sample Effect

Why do we say yes to something free-and end up paying more than we planned? The Sample Effect reveals the hidden psychology behind one of marketing's oldest and most irresistible tricks: the free sample. Drawing from behavioral science, neuroscience, and retail design, this engaging book unpacks how small gestures trigger big commitments, and why something as simple as a taste, scent, or texture can rewire decision-making in seconds. Far from manipulation, The Sample Effect shows how generosity, experience, and psychology intertwine to create value that feels real.
