It's good to have someone you can trust

Sometimes as developers we lose sight of what is right in front of us. A quick change to a piece of code and WHAM, something breaks.

It's times like this that it's good to have someone we trust. We can ask that person to look at our change and help us find the fix, which is often just something extremely stupid that we did.

Too often when we've done something stupid, we look right at the mistake and see it for what it was supposed to do, not what it is doing. A 2nd person can usually find this bug within a few seconds.

This is one of the biggest benefits for paired programming. In those cases there is a lot less chasing your own tail around, because the feedback is immediate. That's why paired programming teams have higher quality and stay focused better.
