The Halo Effect

A single standout trait can completely change how customers see a brand — that's the power of a quiet psychological bias that shapes many buying decisions. This lesson breaks down the mechanism behind the phenomenon, then shows three levels at which it works in marketing: the flagship product, the brand spokesperson, and the design experience. Learners will see why a beauty blogger, a beautiful cafe space, or a "hero" product can carry trust over to an entire product category, through familiar Vietnamese brand case studies such as Vinamilk, IVY moda, and TH True Milk. At the same time, the lesson warns about the equally dangerous flip side — when the halo collapses because of a spokesperson's scandal, the damage spreads fast and is hard to control. From there, learners gain the mindset to choose influencers wisely, build protective contract clauses, and create a lasting halo from the brand's real strengths instead of borrowing credibility from outside.
