How does The Great Gatsby give us insight into anomalies, inconsistencies and paradoxes in human behaviour?

The text shows us that, even if there is no evidence to suggest the real possibility of achieving the American Dream, even if it seems like a total fiction or fantasy, people are willing to believe in it. George Wilson believes that he'll come up with the money to take himself and his wife out west—despite the fact that he's been attempting to get ahead for how many years and remains just as poor as he always was. Gatsby thinks that he can relive the past; in fact, he's absolutely convinced of it, despite the fact that Daisy is married—and a mother—and that he is a criminal who has made his fortune illegally and who can never achieve the status of a resident of East Egg, someone with "old money" instead of "new." We cannot turn back time or bring back the past, and Gatsby's refusal to accept this reality results in his ultimate demise. Similarly, Wilson's refusal to accept the truth—that he will never, ever be able to get ahead, to live the dream—helps lead to his demise as well. When he learned of his wife's affair, he simply began to believe that everything would be fine if they could leave the valley of ashes. However, the text shows that no one can ever really escape their status; neither Wilson nor Gatsby give up, and they both die as a result.
