I’ve noticed that feedback works in 3 situations:
1. “I am asking for feedback and am ready for it. Please give it to me straight.”
2. “You have feedback for me? I feel psychologically safe with you and trust your intentions – so, yes, please give it to me.”
3. “I report to you/believe you have power over my career/life. I will attempt to act on it even if I don’t agree.”
In all other situations, attempts at giving feedback end up achieving nothing.
