How do the biblical stories of Hannah and Job illustrate the consequences of reaching a conclusion before gathering sufficient data?

To my understanding, the consequences that both Eli and Job's friends had incured was that they immediately concluded the matter using their own understanding and experience. Eli concluded that Hannah was drunk when she was in fact, pouring out all of her anguish in her inability to provide her husband a child. While Job's three friends concluded that after seeing Job lose his family, his wealth, and his health, they believed that Job had commited a sin against God and was being punished for it when inactuality, no such sin was ever committed.
