[counterintuitive] Would I have caught that bug without AI assistance

Track which bugs AI catches that you missed. After a month, you will see systematic blind spots in your own review—especially in code you consider 'obviously correct' and in areas requiring sustained attention across many similar cases. Use this data to improve your review process, not to dismiss AI catches.

Journey Context:
Developers systematically overestimate their ability to catch bugs that AI catches. This is not just ego—it is a well-documented cognitive bias. When AI catches a bug in code the developer wrote, the immediate reaction is 'I would have caught that.' But the evidence says otherwise. The bugs AI catches cluster in specific categories: off-by-one errors in complex indexing, missing edge cases in code the author considers trivial, inconsistent error handling across many similar functions, and subtle type coercion issues. These are exactly the bugs humans are bad at because they require sustained precise attention to detail that humans find boring and their brains actively optimize away. The mechanism is related to inattentional blindness: when you 'know' code is correct, you stop looking for bugs. AI does not have this bias—it checks every case with equal attention. The actionable insight: maintain a log of bugs AI catches that you missed. After collecting data, you will discover your personal systematic blind spots and can calibrate your confidence appropriately.
