Final answer:
When a consumer's internal search for information is insufficient, they engage in an external search to gather additional details. This involves researching online, consulting experts, and reviewing other opinions. It is a vital part of the decision-making process to ensure a well-informed conclusion is reached.
Step-by-step explanation:
The consumer demands additional information by engaging in an external search if the internal search lacks enough information. This process involves gathering information from various external sources which may include researching online resources, consulting experts, or seeking reviews and opinions from other consumers. The aim of this is to supplement the initial incomplete information and help make a more informed decision. This informed decision-making process can be seen as a second method, in which comprehensive research is done to learn background information before concluding or making a purchase.
The information search process is crucial as it helps reveal additional details that may not be uncovered in a cursory internal search, and can sometimes contribute to cognitive biases by confirming pre-existing beliefs or assumptions. Nonetheless, it is an essential step in the decision-making process for consumers.
