- Lack of Empirical Evidence: Many economists argue that statistical data does not show clean, regular 50-year cycles. They point to apophenia—the human tendency to recognize patterns in random data. [1, 2, 3]

- Focus on the Short Term: Mainstream economists prefer to focus on shorter, evidence-based business cycles (typically 5 to 10 years) and microeconomic fundamentals. [1, 2, 3]
