Behavioral economics explores how real-world decision-making is influenced by various psychological factors. Adding such factors into the decision-making process challenges the traditional economic assumptions that people always act rationally to maximize benefits. Behavioral economics reveals that human behavior often deviates from logical models due to biases, emotions, and social influences.

For instance, consider a person choosing between two identical brands of toothpaste, one labeled as "10% extra free" and the other as "Now only $2.50." Even if the value is the same, many consumers might choose the first due to the perception of getting more product for free. This reflects how framing choices can influence decisions.

Another example involves loyalty cards at coffee shops. A card that offers a “free coffee after 10 purchases” motivates customers to return, even if the savings are minimal compared to buying a larger, discounted pack of coffee. Behavioral economics explains this through the concept of goal-oriented behavior, where people are driven by the sense of progress toward a reward.

Emotional factors also play a role in spending. For example, someone shopping after a stressful day might buy items they don’t need because spending provides immediate emotional relief. Such behavior illustrates how emotions can override rational decision-making.

Behavioral economics also highlights how default settings influence choices. For instance, many individuals are more likely to stick with pre-selected options in software or subscription plans rather than actively exploring alternatives, even if better options are available.

By focusing on these psychological and social factors, behavioral economics provides a clearer understanding of how people make decisions, helping to design systems and strategies that better align with actual human behavior.
