Background: The issue of ethics in commercial relations between the buyer and the seller is highly significant and if there are no solutions to ethical problems in these areas, the continuation of this process will lead to a shake-up in trade and commercial communications from the lower layers that are consumers up to the upper layers that are major traders. The first articles on ethical issues were published in the 1960s and were mostly philosophical articles. In such an atmosphere, having a good understanding of consumers' ethical behaviors and the process of consumption includes several advantages. These benefits include helping managers in their decision making, providing a cognitive basis through analyzing consumer behavior, helping legislators, and regulators to lay down rules for the purchase and sale of goods and services, and ultimately for consumers in the decision-making process. The purpose of this study is to investigate ethics in the of sports consumer behavior. In fact, researchers have found that observing ethical issues in transactions not only from the seller and the marketer's side, but also, from the consumer's side is important. Conclusion: The results of the review of the research done on the relationship between individual factors such as age, gender, religion, and moral intensity show that in most cases, these variables have had an impact on ethical decision making. Therefore, further research in this area should be made to clarify the certainty of these effects.
