[counterintuitive] Why doesn't asking the model to 'check your work' or 'reconsider' actually fix its reasoning errors?

Never rely on self-correction prompts alone. Always provide external grounding: executable test cases, tool execution results, retrieval-augmented verification, or human feedback. Self-correction only works reliably when the model receives new information from outside its own generation.

Journey Context:
The common pattern is: model makes an error → developer adds 'double check your answer' to the prompt → model sometimes gets it right → developer assumes self-correction works. Research shows this is largely illusory. Without external feedback, the model's 'self-correction' tends to either \(a\) reaffirm its original answer, \(b\) change to a different wrong answer, or \(c\) converge to the right answer only when the task is simple enough that the model already had the capability. The model cannot verify its own reasoning because it doesn't have access to ground truth — it's generating more tokens conditioned on its previous \(potentially wrong\) tokens, creating a circular verification loop. The appearance of self-correction on easy tasks masks the complete failure on hard tasks where correction matters most. True self-correction requires external feedback that introduces genuinely new information.
