No code reviews by default
&gt; Pull requests don&#x27;t prevent bugs.<p>I remember once I was giving a talk on code review and I said that code review doesn&#x27;t prevent bugs and people were shaking their heads. Everyone hangs on to this one thing, but if you look at the majority of pull requests that have been approved you&#x27;ll see a lack of comments about pontential bugs. Also, if you do see a comment about bugs they&#x27;ll often be disregarded. This drives me up the wall when I&#x27;ve previously pointed out bugs and they&#x27;ve been found to be actual bugs and had to be fixed.<p>I think the biggest problem with code reviews is it often becomes adversarial and people want to come out on top. I&#x27;ve had it more than once that someone has suggested another way of doing something, when I asked what the benefit of that way was or what was the downside of the way I was doing it no answer was forth coming however I was expected to implement their way. This becomes enraging when you point out flaws in their way but they can&#x27;t find any benefit of their way.<p>As well as, often people just don&#x27;t want to do the extra work. You point about a bunch of small improvements. It&#x27;s a pain.<p>You end up with people asking for code style changes even tho there is a code style and the changes they&#x27;re asking for aren&#x27;t in those guidelines-<p>In my opinion, code review is a massive waste of time that is often done purely as cargo cult. People know it&#x27;s a good thing to do but people have no idea how to code review and what is and what is not benefical during code review.
