Human Needs and Demands

Human needs and demands have physiological, psychological, sociological and environmental roots. The best decisions made by a consumer on how to spend their income should be based on the marketplace choice to obtain more for less. However due to the buyer wants roots, they tend not to pay attention to the market decision, and hence they become
wasteful and careless shoppers. The instability of human needs and the capability of consumers desire to expand indefinitely, contributes to the ability not to satisfy human needs.
The increase in income leads to an increase in the human desire to purchase new goods and services and hence the level of satisfaction targeted cannot be reached.  Based on the satiety principle of consumption people will always come up with the unending reason for buying something new. Most consumers do not have an intuitive sense that enables them always to make choices that will promote their welfare. Most customers want goods and services that are not essential to life itself but rather those that are necessary for a more complete, abundant life. The geographical location also affects the needs of a consumer and how to spend their income.
Consumer behavior goes hand in hand with understanding the psychology of individual consumers since they have different personalities. For example, while choosing shoes a person selects a particular item not just for protection but rather considers their appearance.  Other than that, people have different types of pleasures which are controlled by the different senses. For example, a consumer who is blind may have no desire for movies. It is often quite difficult to measure the intensity of satisfaction people feel when consuming a product or service. To understand the consumer’s behavior, more scientific research is needed.
