OK, that might be overselling it.
Awhile ago I came across this article that mentioned this magic ratio for how much positive to negative feedback you should give.
Apparently if you want your constructive feedback to be heard and considered, we need to have balanced that with positive comments and feedback, and the ratio is 5.6 to 1.
Interestingly this applies to your personal life as well:
"For those couples who ended up divorced, the ratio was 0.77 to 1 - or something like three positive comments to every four positive ones."
You should be careful sharing this tidbit in a workshop though. I once did that without realising one of the attendees was going through a messy divorce at the time. Oopsee.
I have some catching up to do. Do you?
