If not, then don’t ask. The worst thing you can do is ask for opinions and then argue about what others tell you. Realize that their frankness can uncover your blind spots.
Instead, show that you hear the criticism by nodding, for example. Then pose a clarifying question: “Do I understand you to mean that …”
If you accept the criticism, say so, to show you can absorb a blow gracefully. Example: If they say, “There’s something wrong here,” reply, “You’re right. What would you do to improve it?”
Caveat: Don’t reward petty or snide remarks with a thoughtful response. Just say,“Thanks for the feedback.”
