You my view my Amazon review here.
On page 23 there is a really great question in regards to communication:
"If your audience knew everything you know about your subject, would they think you had portrayed it fairly?"
3 standards for ethical communication from this book:
1) It is factually correct.
2) It is intended to achieve a constructive outcome which the audience would support.
3) It will not cause members of your audience to act in a way that harms them.
I highly recommend this book. It makes my general recommended reading list and my top 21 list.
