It’s a bit of a change of mindset to begin thinking that you can’t trust a PR even a little.

It has never occurred to me that other people trust PRs, even a little. I mean, that they might think about it in those terms.

This explains a lot to me.

Why does it take me longer to review code than other people? They trust the person who wrote it, but I don't.

Why is it that when my coworkers think a person is untrustworthy, that they always end up begging me to do all of that person's reviews. It's because I'm not bothered by that. I already treat everybody as untrustworthy.

I've never understood how other people think when they do reviews, I guess.
