Buyer's remorse is the sense of regret after having made a purchase. It is frequently associated with the purchase of an expensive item such as a car or house. It may stem from fear of making the wrong choice, guilt over extravagance, or a suspicion of having been overly influenced by the seller.
Buyer's remorse is thought to stem from cognitive dissonance, specifically post-decision dissonance, that arises when a person must make a difficult decision, such as a heavily invested purchase between two similarly appealing alternatives. Factors that affect buyer's remorse include resources invested, the involvement of the purchaser, whether the purchase is compatible with the purchaser's goals, and what positive or negative evidence the purchaser encounters post-purchase that confirms or denies the purchase as a good idea. Sometimes the term "buyer's remorse" can be applied to lifestyle decisions too.
The anxiety may be rooted in various factors, such as: the person's concern that they purchased a current model now rather than waiting for a newer model, purchased in an ethically unsound way, purchased on credit that will be difficult to repay, or purchased something that would not be acceptable to others.
In the phase before purchasing, a prospective buyer often feels positive emotions associated with a purchase (desire, a sense of heightened possibilities, and an anticipation of the enjoyment that will accompany using the product, for example); afterwards, having made the purchase, they are more fully able to experience the negative aspects: all the opportunity costs of the purchase, and a reduction in purchasing power.
Also, before the purchase, the buyer has a full array of options, including not purchasing; afterwards, their options have been reduced to:
- continuing with the purchase, surrendering all alternatives
- renouncing the purchase
Buyer's remorse can also be caused or increased by worrying that other people may later question the purchase or claim to know better alternatives.
The remorse associated with some extreme shopping activity may be, again, a sign of some deeper disquiet; normal "buyer's remorse" should not be confused with the complex emotional dynamics of "shopaholic" behavior, any more than eating too much on special occasions should be confused with a serious eating disorder such as bulimia.
Cognitive dissonance 
The phenomenon of buyer’s remorse has been generally associated with the psychological theory of cognitive dissonance, a state of psychological discomfort when at least two elements of cognition are in opposition, and which motivates the person to appease it by changing how they think about the situation. Buyer’s remorse is an example of postdecision dissonance, where a person is stressed by a made decision and seeks to decrease their discomfort. The buyer may change their behavior, their feelings, their knowledge about the world (what they thought the purchased item would be like), or even their knowledge of themselves. The more resources such as money, time, and cognitive resources that are invested into making a purchase, the more likely the buyer will experience buyer’s remorse or psychological discomfort.
Psychologists have focused on three main elements that are related to cognitive dissonance and buyer’s remorse. They are: effort, responsibility, and commitment. Effort is the resources invested in a purchase (material, intellectual, psychological, and others) and effort is directly related to the importance of the purchase. Purchases that require high amounts of effort but don’t bear high rewards are likely to lead to buyer’s remorse. Responsibility refers to the fact that the purchase is done out of free will. Buyers that have no choice on the purchase will be less likely to feel dissonance because it was not out of their own volition. Commitment refers to the continuing of an action. The purchase of an automobile has high commitment because the car must be driven for usually a long duration. Purchases with higher commitment will lead to more buyer’s remorse. Low rewards matched with these three conditions will most likely result in buyer’s remorse via cognitive dissonance. The buyer feel anxiety and psychological discomfort because their behavior (the purchase of the item) does not match their attitude (they expectation of the purchased item).
The following scale was developed by Sweeney, Hausknecht, and Soutar in a study to investigate three elements (one emotional, two cognitive) of buyer's remorse.
|Elements of Cognitive Dissonance (22 Items)|
|Emotional||After I bought this product:|
|I was in despair|
|I resented it|
|I felt disappointed with myself|
|I felt scared|
|I felt hollow|
|I felt angry|
|I felt uneasy|
|I felt I'd let myself down|
|I felt annoyed|
|I felt frustrated|
|I was in pain|
|I felt depressed|
|I felt furious with myself|
|I felt sick|
|I was in agony|
|Wisdom of purchase||I wonder if I really need this product|
|I wonder whether I should have bought anything at all|
|I wonder if I have made the right choice|
|I wonder if I have done the right thing in buying this product|
|Concern over deal||After I bought this product I wondered if I'd been fooled|
|After I bought this product I wondered if they had spun me a line|
|After I bought this product I wondered whether there was something wrong with the deal I got|
There may be a duality of attitudes that explain how a person may be satisfied with their purchase but have the intention to never repeat the purchase. For example, a husband who takes his wife to the most expensive restaurant in town for their anniversary only to find that the food and service does not meet his expectations might still be satisfied with his decision to go to the restaurant but have the intention to never return. In this extension of cognitive dissonance, the duality of satisfaction and intention are separate phenomena within buyer’s remorse.
In social psychology, "involvement" describes the effort, investment, and commitment in purchases. Involvement is often coupled with cognitive dissonance to explain buyer’s remorse. In most cases, purchases with high involvement that results in cognitive dissonance is harder to overcome than purchases with low involvement that result in cognitive dissonance. The more involvement that a purchase requires or the purchaser puts in, the more dissonance or psychological discomfort the buyer will experience if dissatisfied with the purchase.
Studies investigating the link between cognitive dissonance and impulse buying have shown that impulse buyers experience less cognitive dissonance when they are disappointed with their purchase. The main explanation for this is that impulse buyers go into the purchase already without high expectations. Another possible explanation is that impulse buyers who are dissatisfied with their purchase attribute the poor purchase to their personal “impulse buying” fault rather than on the purchased item itself.
The paradox of choice 
The paradox of choice is a theory by American psychologist Barry Schwartz claiming that, after a certain threshold is reached, an increase in the number of choices will cause a significant amount of psychological distress. This distress, according to Professor Schwartz, can manifest itself in many ways. One way is through buyer's remorse. The theory states that buyer's remorse is created through increasing opportunity costs associated with increased choices. Opportunity costs associated with alternate choices compound and create strong feelings of dissonance and remorse.
As the number of choices increase, it is easier to imagine a different choice that may have been better than the one selected. The constant comparison to one's expectations induces regret, which reduces the satisfaction of any decision, even if it fills the individual's needs. When there are many alternatives to consider, it is easy to imagine the attractive features of rejected choices and there is a decrease in overall satisfaction.
Consider the amount of choices in a simple supermarket. There are likely to be many different options for single type of product. With so many to choose from, the customer might expect that one of the available options must be perfect for their needs and will have no drawbacks. This leads to expectations rarely being met, a significant psychological issue. In the example of a supermarket, buying the wrong product may not be a significant mistake. For more involved decisions, the consequences of a wrong decision are significant.
Reducing buyer's remorse 
Choice-supportive bias leads to an increased liking of one's choices, including purchases. This seems to contradict the concept of buyer's remorse, however this choice enhancement can collapse when presented with even minor indication that the wrong choice was made. While initial positivity towards a decision is greater for more difficult decisions, this positivity also has greater vulnerability to evidence of an incorrect choice. This effect is larger when the purchaser is more involved in the decision. However, buyer's remorse can be reduced by post-purchase confirmation, though post-purchase communication may aggravate a buyer's discomfort if the purchase did not line up well with the buyer's predominant goals. Indeed if the purchase lines up well with an individual's goals there will be less post-purchase dissonance which means there will be less remorse and greater decision satisfaction.
Marketing implications 
Buyer's remorse is a powerful experience for consumers. For years, marketers have been attempting to reduce buyer's remorse through many different methods. One specific technique employed by marketers is the inclusion of a coupon towards a future purchase at the point of sale. This has many benefits for both the consumer and retailer. First, the consumer is more likely to return to the store with the coupon, which will result in a higher percentage of repeat customers. Each successive time a purchase is made and is deemed satisfactory, buyer's remorse is less likely to be experienced. Customers can justify their purchases with product performance.
Another technique used is the Money Back Guarantee, a guarantee from the retailer that the product will meet the customer's needs or the customer is entitled to a full refund. This technique is highly successful at lessening buyer's remorse because it immediately makes the decision a changeable one. The unchangeability of an "all-sales-final" purchase can lead to a larger amount of psychological discomfort at the point of the decision. This makes the stakes higher, and poor choices will cause significant buyer's remorse.
