👉 Thanksgiving engineering, also known as the Thanksgiving Effect, is a cognitive bias where individuals tend to overestimate the likelihood of positive outcomes and attribute these favorable results to their own actions or decisions, especially when they receive external rewards or assistance. This phenomenon occurs during the Thanksgiving holiday, a time when people are often more inclined to express gratitude and acknowledge the contributions of others. As a result, individuals may attribute their success or the positive outcomes they experience to their own efforts, attributing them to personal agency rather than external factors. This bias can lead to an inflated sense of self-importance and a tendency to downplay the role of luck or others' help in achieving success.
