Knowledge is the sum of all information known by a person. It is the facts of the world as he/she knows it and the depth of knowledge is a function of the breadth of worldly experiences and the strength of an individual’s long-term memory. Obviously what exists as knowledge to an individual depends on how an individual’s perceptual filter makes sense of the information it is exposed to.
Marketers may conduct research that will gauge consumers’ level of knowledge regarding their product. As we will see below, it is likely that other factors influencing consumer behavior are in large part shaped by what is known about a product. Thus, developing methods (e.g., incentives) to encourage consumers to accept more information (or correct information) may affect other influencing factors.
