CORE DEFINITION

The model is too simple to capture the underlying structure and patterns in the data. It is like fitting a straight line to a complex curve, which neither remembers the training data nor can predict the future.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Cognitive rigidity. When you try to explain complex social phenomena with 'black-and-white' thinking or 'one-sentence aphorisms', you are underfitting. Although it saves effort, such a model has no explanatory or predictive power for reality.

anchor

Anchor fast decisions

Insufficient model capacity or inadequate training, high bias, high error on both training and test sets; corresponds to applying overly simplified frameworks to complex reality in cognition.
