perplexity
State of confusion
Perplexity is the state of being puzzled or confused, especially when facing something difficult to understand or resolve: Her perplexity deepened as the instructions contradicted themselves.
The word suggests a mental tangle—not mere ignorance but active bewilderment when things don't add up.
In technical contexts, perplexity is a metric measuring how well a probability model predicts a sample; lower perplexity indicates better prediction.
