Code Review: Should the results of a code review count against you?
No.

Quote:
“Code reviews often start off on the wrong foot because they are perceived as an unnecessary step that has been forced upon the developers or, in some cases, evidence that management doesn’t trust the developers. Neither of these perspectives is accurate. Code reviews are a proven, effective way to minimize defects. Whatever additional motivations the organization has for performing code reviews, they are, at their core, an industry best practice.
– Robert Bogue

Application:
Catching defects this early in the software development process saves the company money and results in a much higher quality product. A peer review should never be associated with lack of knowledge or confidence, but with openness and a willingness to learn best practices as a group.
