How To Disagree Gently And Then State Your Idea
Listen attentively to the other person’s idea/strategy.
Then say: “That is certainly a PLAUSIBLE idea/strategy. Could I add another strategy that I’d like for us to consider for three reasons.” Or “Is like to add to that idea.” Etc.
This response has several advantages. One.It acknowledges that the other person has made a useful contribution. Two. The word “plausible” implies that the idea/strategy has strong points and possible weak points that need to be assayed. The word actually invites examination of strengths and weaknesses. Three. The word “plausible” gives you an opportunity to add your idea to the assay.
