People are not equal in (sub-(sub-))domain experience. And we all can be distracted or dumb sometimes. Consider how powerful rubber ducking is : it works even when you're not talking to another person ! (And you might not think about doing it in a stressful situation.) It just needs to be done tactfully. And in case it was a stupid mistake, defuse the ego issues by telling an anecdote about how you've made a similar one. (It's even helpful if it was a dangerous mistake : telling how you got punished, but the world didn't end.)
