In this video, we delve into the concept of the sunk cost fallacy, a critical psychological bias that often plagues decision-making, particularly in the realm of day trading. I explore how our emotional investments—comprising time, effort, and money—can skew rational judgment and lead to suboptimal financial decisions. By understanding the dynamics of this fallacy, we aim to foster better decision-making practices that are not anchored by past investments but are driven by objective outcomes and logic. We'll also discuss practical strategies to recognize and overcome this cognitive bias, enhancing our trading methodologies and personal growth.
