Ability and knowledge
A consumer who is, for example, a beginner at playing the violin is unlikely to
spend thousands of pounds on a Stradivarius. Ability therefore affects some buying
decisions. Likewise, pre-existing knowledge of a product category or brand will
also affect the way the consumer approaches the decision. Pre-existing knowledge
is difficult for a marketer to break down; it is much better to try to add to the
consumer’s knowledge wherever possible.
