There isn’t a clear logical or computational method for determining whether one explanation is better than another. However, David Deutsch offers useful criteria for evaluating explanations. He suggests that a good explanation is better than a rival if it explains more — meaning it has fewer errors, fewer loose ends, or a broader explanatory range (i.e., it accounts for more phenomena) <my interpretation, not a quote>.

I believe Popper also describes a solution to be better if it has less unintended consequences than a rival idea. <my interpretations, not quotes>.
