The "Stern Effect"

The "Stern Effect" refers to the phenomenon where a person's approval or endorsement significantly boosts the credibility, popularity, or sales of a product, person, or idea. Named after media psychologist Dr. Robert Stern, it highlights how influential authority figures—like celebrities, experts, or respected individuals—can shape public perceptions simply through their support or recognition. This effect underscores the power of trusted voices in influencing decisions, often leading audiences to perceive endorsed items or ideas as more valuable or credible based on the endorsement alone.
