What is the main idea of drive theory?

Drive theory is a psychological concept that explains motivation as an internal state that pushes individuals to fulfill basic biological needs. The main idea is that human behavior is driven by the desire to reduce internal tension caused by unmet needs, such as hunger, thirst, or the need for warmth. When these needs are not satisfied, they create a drive, which is an uncomfortable state that motivates individuals to take action to restore balance or homeostasis. Once the need is fulfilled, the drive is reduced, and the individual returns to a state of equilibrium. This theory is often associated with the work of Clark Hull and his formula for drive reduction.
