An investigation of big life decisions

What are life’s biggest decisions? In Study 1, I devised a taxonomy comprising 9 decision categories, 58 decision types, and 10 core elements of big decisions. In Study 2, I revealed people’s perceptions of and expectations for the average person’s big life decisions. In the flagship Study 3, 658 participants described their 10 biggest past and future decisions and rated each decision on a variety of decision elements. This research reveals the characteristics of a big life decision, which are the most common, most important, and most positively evaluated big life decisions, when such decisions happen, and which factors predict ‘good’ decisions. This research contributes to knowledge that could help people improve their lives through better decision-making and living with fewer regrets.
