Those words are for the most part interchangeable. It depends on who is using them and on the context that we can draw meaning.

Here is more for you.

I usually see framing as what is done early on to establish the frame of reference we want the other person to see from. This establishes the greatest probability of us winning right off the bat.

Spinning I see as changing the frame others set to our advantage.

And positioning is another way of saying framing.

All this said, the terms are still largely interchangeable.

I hope this helps.

the lines between “framing”, “spinning” and “positioning” are kind of blurry in my mind. Could you turn the contrast a bit up and help me to draw some clear distinctions between these three concepts?

Thanks,
