Criticism and Disagreement

At an advanced level, effective communication tis more than simple politeness you need to know how to disagree with more senior people in a way that lets them save face, and choose the right words to avoid conflict. Direct contradiction or blunt criticism can make people angry and make it harder to get what you want. So you need to disagree politely and criticize, with diplomatic language.
Advanced speakers don't usually directly tell someone that they are wrong. Instead, they disagree by agreeing. This method is sometimes called 'Yes. But ...'
For example:
Native English speakers understand that direct criticism is seen as aggressive. So they use 'softening words' and 'qualifiers'.

| Blunt / Absolute | Softer |
| You are wrong | There are some things you need to consider here ... |
| That won't work | There are some things we need to improve with that idea |
| You are completely wrong | Are you sure about that? |
In fact one way an English speaker can signal that he completely disagrees is just to raise one eyebrow and say in tomes of deep interest 'Really?'

For example:

For example:
Not "You didn't do that job properly."
Instead "There are still some things to do here"
Not "You are talking nonsense."
Instead "There are some things that we need to clarify first."
The right words can make criticism or disagreement less painful
For example:
Informal and diplomatic – same meaning different words.
| Direct / Informal Register | Executive / Academic Register | Functional Strategy |
| "You're wrong." | "Well, that is one opinion" | Not agreeing |
| "That makes no sense." | "I don't follow." | My fault not yours |
| "I hate this idea." | "Maybe there's another way" | Avoid confrontation |
| "You missed the point." | "Let me put it another way." | Say it again |
| "That's impossible." | "Good, but what about ...?" | Show the problem |
| "Fix these mistakes." | "There are a few things that can be improved here." | Make it better |
