Customer Satisfaction and Word of Mouth

Do consumers complain or praise more?

Telling other people about your experiences with a company of product is something many people do. This may be evangelizing their newly purchased laptop, or gripe about the slow service at a restaurant. Word of mouth is defined as informally communicating with a third party about goods and services, rather directly telling the company.

There are 3 theories about consumers engaging in word of mouth.

  1. Highly satisfied consumers engage in more word of mouth, because
    • they want to help others,
    • appear well informed or smart,
    • engage in ego defense,
    • reduce cognitive dissonance,
    • present themselves in a positive light;
    • they may have a general bias towards positive things,
    • or want to avoid saying negative things.
  2. Dissatisfied consumers engage in more word of mouth, because
    • they want to vent hostility,
    • reduce anxiety,
    • warn others,
    • or seek vengeance.
  3. Consumers engage in word of mouth more if they are extremely satisfied or dissatisfied, because
    • they will have a greater impact, hence more utility when they engage in word of mouth in a more extreme situation.

Word of mouth activity is also predicted to increase at a greater rate for dissatisfied consumers than satisfied consumers, since negative information about products is less common and has a greater effect.

A study indicates that theory 3 is more likely than the other two, since the resulting data is a U-shaped model, where highly satisfied and dissatisfied consumers engage in greater word of mouth. The hypothesis that negative word of mouth increases at a greater rate is also supported by the data.


The study replicated similar findings in both the United States and Sweden, indicating that word of mouth practices are likely universal.

    I always tell my friends when I get screwed over with a product or service. Even just a little. But I don’t tell people about great products unless they’re really really great. Like my calphalon hard anondized cookware (no I’m not a shill).

    Thanks for writing, great post!
