When a group wants to give each other honest, kind feedback

Good critique is a real skill, and a group that learns it becomes precious, for it dissolves the false choice between honesty and kindness. Speak to the work, not the person — there is a great difference between saying a passage confuses you and saying the writer is careless, so keep critique on the piece itself, which lets you be fully honest about the work while remaining kind to the maker. Name what works, not only what fails — a maker needs to know their strengths as much as their weaknesses, and a critique of only problems leaves them unable to tell what to keep and slowly demoralizes them, so name the successes as carefully as the faults. And offer your response, not your rewrite — say what the work did to you, where it worked and faltered for you, rather than telling them how you would have made it, for the maker owns the vision and your job is to be an honest mirror, not to remake their work in your image. Speak to the work, name the strengths, offer your response. What's hardest about feedback in your group?
