Which issue occurs when the modeling process fails to account for outcomes the model cannot represent?

• A. Neglecting Limitations
• B. Data Snooping
• C. Overfitting
• D. Underfitting

Answer: (A)

Neglecting limitations occurs when the modeling process ignores outcomes the model cannot represent. When a model only covers a subset of possible states, it leaves blind spots for tail events, regime changes, or data gaps, causing risk underestimation and weaker controls because the model isn’t aware of its own bounds. This idea highlights why it’s crucial to acknowledge what the model cannot capture and to supplement it with scenario analysis, stress testing, or model validation. This concept differs from overfitting (model capturing noise), underfitting (model too simple to capture relationships), and data snooping (biased evaluation from test-data leakage).
