Grace is talking with her wife, myanna. myanna starts crying, and grace immediately assumes that myanna wants a divorce. what kind of cognitive distortion is this?

The answer is jumping to conclusions. It is a psychological word stating to a communication hindrance where one "judge or decide something without having all the facts; to reach unnecessary conclusions". This is also known as or abbreviated as JTC.

The correct answer is jumping to conclusions.

Grace didn't really give this situation much thought - she just assumed that her wife Myanna wants to get a divorce just because she started crying while they were talking. There was no solid proof for her to start thinking that way, which is why she just jumped to conclusion without actually asking her wife what's wrong.
