Thank you for your thoughtful insights. You're absolutely right—machines do not inherently understand doubt. Instead, their response is shaped by the semantic associations they have learned during pretraining. The word "Wait" is not an instruction to doubt, but a linguistic signal that, in human language, frequently precedes hesitation, revision, or reevaluation. The model, having been trained on vast amounts of such text, predictively aligns its behavior with this pattern, triggering a self-correction process—not because it "understands" doubt, but because it has statistically learned that doubt follows "Wait."
