Psychology explains why people always choose the same mug at home, and why it becomes so hard to replace

Psychology explains why many people instinctively reach for the same mug every morning. Research suggests this everyday habit is shaped by the endowment effect, emotional attachment, habit formation and the mere exposure effect. Over time, ownership, memories and familiarity make an ordinary mug feel more comforting and valuable, making it surprisingly difficult to replace even when newer alternatives are available.
