The article I read was titled "Speculations, Assumptions and Projections" by Linda and Charlie Bloom This article got to the heart of an issue I think we all have in relationships and that is doing these 3 things. We undermine our partners by making speculations about what they feel or assuming we know what they need, want or feel and then projecting our ideas onto them.
They explain that assumptions are speculations from our minds driven by a bias towards our perspective that may or may not be accurate. They go on to show us that if in our relationships we will be curious and open to seeing what is actually going on with our partner, instead of confusing our own imaginings with reality, then we will learn to understand their perspective. As they say....don't be a SAP. Be open to learning, listening and hearing instead of forming our own opinions.
