Disagree and Commit!

https://finance.yahoo.com/news/jeff-bezos-says-using-phrase-124500051.html

After reading (still in the middle of it) Creativity, Inc., I’ve come to dislike the word “honest” even more.

When people who are trying to persuade someone and they use the filler of "I"ll be honest with you, blah, blah, blah..."
I hate that.

From the article in the hyperlink above:
“It's also a way to be honest and supportive, two traits one top Silicon Valley CEO coach says are crucial to running a great team."

A better word to use is candor.  Being candid means people can be honest without all the underlying morality issues.

The article doesn’t address what exactly happens when they disagree and also don’t want to commit.  I suppose the idea dies, or hibernates until a different decision maker comes into the picture.  But then of course you might have some underlying resentment and frustration build up in the person whose idea was crushed.
