Solution

  • First impressions matter. The Halo effect depicts that people do judge a book by its cover. Having a good initial experience with a product tends leads to higher rating of intuitiveness, reliability, and security of the rest of your product and experience.
  • Spillovers happen. People’s perception of one aspect of an organisation, such as its customer service, can influence how people perceive the rest of its operations and the company as a whole.

Rationale

We tend to like (or dislike) everything about a person – including things we have not observed. We strive toward maintaining a simple and coherent view of the world and suppress ambiguity. We interpret things in a way that makes them coherent with the context. The halo (positive) and horn (negative) effects increases the weight of first impressions – sometimes to the point that subsequent information is mostly wasted.

Consumers are willing to pay more money for a brand they already know and trust. Subsequent new products by a brand will benefit from the brand’s halo effect.

Discussion

The halo effect was originally identified in 1907 by the American psychologist Frederick L. Wells (1884-1964), but only officially recognized and coined as a term by psychologist Edward Thorndike in 1920. Thorndike originally coined the term referring only to people; however, its use has been greatly expanded especially in the area of brand marketing.

The opposite of the halo effect is the horn effect, named for the horns of the devil. When consumers have an unfavorable experience, they correlate that negative experience with everything associated with a brand.
