Not the parent, but I reached that same conclusion.

You're not trusting them blindly because any and every ethical protection you decide your procedure needs, will be there. In addition to the ones the IRB thinks need to be there too.

When you implement a workplace safety policy in your company, making it comply with OSHA regulations isn't "blindly trusting authority to decide what is safe". If you think a practice is unsafe, yet OSHA thinks it's safe enough, they're not gonna prevent you from taking more precautions.

Same deal with code reviews. You aren't blindly trusting your colleague to decide what is bad or good code. You're adding their polish to yours.
