“Justify” suggests you are referring to not being “to emotionally attached” to your solution.

I like this :). “rationally explain”

I think when you’re new to having code reviewed, it can be hard to take emotion out of it (at least that has been my experience).

I think the key is. Avoid getting defensive (waiting 5 mins is often effective). Go through your decisions (now with new information). See if where you land with the solution changes.
