Here's another problem with radical honesty: You think you're right, and say something that's going to be a painful but beneficial truth. But you might simply be wrong: you don't have all the facts, you're missing some context, your interpretation is hampered by your own issues, whatever. Now you've caused someone pain and haven't helped them, and maybe further contributed to their problems.

Radical honesty works great with I-statements (e.g., "I stopped listening to you a couple minutes ago because you're boring me") in terms of communicating effectively without the baggage of courtesy. But radical honesty for criticism rarely works as well as propenents think.
