The document discusses how what people know can limit their potential if they are not exposed to new information and learning opportunities. It provides examples of how elephants, customers, investors, and potentially employees are influenced by the knowledge that authorities like trainers, companies, financial institutions, and employers decide they should have.

The document suggests exposing people to a broader range of positive and negative information so they can make more informed choices.
