Behavioral economists believe that people:

A. assess current and future options equally well.
B. make errors in decision making because of problems such as bad C. information, but such errors are random and generally not repeated by the same individual.
D. do not care about fairness, especially if it impairs their ability to get what they want.
E. often succumb to temptation.

option D

Explanation:

In an ideal situation, people would always make optimal decisions that provide them with the greatest benefit and satisfaction.

This theory assumes that people, given their preferences and constraints, are capable of making rational decisions by effectively weighing the costs and benefits of each option available to them. The final decision made will be the best choice for the individual. The rational person has self-control and is unmoved by emotions and external factors and, hence, knows what is best for himself. Alas behavioral economics explains that humans are not rational and are incapable of making good decisions.

you don't if you paid you paid. it's like if i bought a computer and used it then i say idon't want it anymore so im gonna return it. you can't. unlkess you have your reciept

cognitive overload: having a lot on your mind impairs decision-making and tends to result in the simplest, but not necessarily best, option being selected.

empathy gaps: overlooking how you might feel in a different situation can result in unnecessary purchases, such as overbuying when shopping for food on an empty stomach.

optimism and overconfidence: wearing rose-tinted glasses and having unrealistic expectations about the future can affect money management and leave you unprepared for a change in circumstance.

instant gratification: seeking instant gratification drives impulsive spending and can undermine long-term planning and savings.

harmful habits: automatic or mindless behaviour can amplify a poor financial decision as it becomes a recurring event.

social norms: we are heavily influenced by the actions of others; while this can be in certain circumstances, it also contributes to the pressure to keep up with the joneses through conspicuous consumption.
