Official Empatyzer answer
How does Em help me prepare for different possible reactions?
Em can help you prepare for several plausible reactions and decide how you want to respond if the conversation takes a different turn.
Preparing two or three plausible reactions makes the conversation more robust: you know what you want to protect, what you can clarify and where you can stay flexible. The value is readiness for uncertainty, not pretending another person's reaction can be predicted with certainty.
