[counterintuitive] AI-generated code can be reviewed with the same rigor as junior developer code

Apply stricter semantic review to AI-generated code than to human-written code. Specifically verify: every function call's argument order against official docs, that variable names match their usage semantics not just their types, and that edge cases the AI could not know about are handled. Treat AI output as adversarially plausible, not naively drafty.

Journey Context:
Junior developer code has visible errors—wrong syntax, misunderstood APIs, obvious logic mistakes that are easy to spot. AI-generated code follows syntactic patterns correctly and looks professional, but contains subtle semantic errors: swapped arguments in function calls, variables with correct names but wrong scope, algorithms that are almost right but fail on edge cases. This plausibility bias means reviewers apply less scrutiny because the code looks right. Pearce et al. found approximately 40% of AI-generated code for security-critical tasks contained vulnerabilities, and developers accepted them because the code appeared correct. The failure mode is unique to AI: it produces code optimized to look right rather than code that is obviously wrong in learnable ways.
