When a sentence has two parts—the first part positive and the second part negative—the conjunction makes a big difference in how the complete sentence is received.
“You played that song really well, but this note should be two beats.”
“You played that song really well, and this note should be two beats.”
“You played that song really well. Next time, play this note two beats.”
Those sentences feel different as the receiver.
“But” in the middle negates the first half of the sentence.
“And” in the middle leaves both parts of the sentence intact.
This trick (that is easy to do
but and hard to remember) improves message reception in nearly any context: work, spouse, kids, friends, teammates.
Of course—there is a boundary on your responsibility for your message being received as intended. And there’s context. Simply using and instead of but doesn’t change those variables.
Someone who is programmed to reject praise and focus on negative isn’t going to hear the goodness up front, regardless what follows. (That doesn’t mean you shouldn’t try.)
Someone whose work is never good enough or who has been pounded with criticism perhaps should be offered only the compliment, with the second half saved for just before the next attempt. (“Remember when you do this to include xyz detail.”)
And, because I have a child who is That Age, I can’t write a post with that many “but”s in it without thinking “chicken butt!”
