Brands are like people, they have personalities. Well not quite, we as consumers tend to attribute human like personalities to brand. If we are allergic to certain human personalities, can we be allergic to brands too?

While this level of brand sensitivity and reaction reads like hyperbole, there is certain truth to the emotional response. In her 1997 paper in the Journal of Marketing Research, Prof. Jennifer Aaker described five dimensions of brand personalities:
- Sincerity
- Excitement
- Competence
- Sophistication
- Ruggedness
If a brand’s personality dimensions are not aligned with those you require of a brand, the brand is bound to cause a negative response.
