The 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.
