Explain how the example from the professor s lecture illustrate the choice supportive bias

Choice-Supportive Bias
People often make decisions by considering the advantages and disadvantages of each option. However, after a person selects an option, there is a tendency for that person to exhibit the choice- supportive bias. After selecting an option, a person may begin to favor that option. Without being fully aware of it, people who exhibit this bias tend to focus on and remember only the advantages of the option they selected. As time passes, they will overlook the option’s disadvantages, eventually even forgetting them.
