What approach should future predictions be based on according to the model?

• A. Past history, not current trends.
• B. Current trends only.
• C. Random samples.
• D. Personal opinions.

Answer: (A)

Predictions should be based on past history because historical data reveal the enduring patterns and relationships that govern future behavior. Looking at a long record lets the model learn the underlying processes, such as seasonality, cycles, and persistent trends, while smoothing out random noise. Relying on current trends alone can be risky since trends may be temporary or driven by a short-lived shock, and they can reverse or change as conditions shift. By grounding forecasts in the historical data, the model estimates stable relationships and probabilities rather than overreacting to what’s happening right now. Using only random samples or personal opinions would lack the data-driven evidence that history provides.
