Retroactive revision means changing what you said. Anyone can do it but retroactive revision is especially designed for FIML partners. Partners can use it whenever they feel a statement they have made has boxed them into a corner or is making the conversation take a turn they had wanted to avoid.
For example, you say “I like XYZ cars the best.” What you actually meant is I very much like XYZ cars. Your partner starts talking as if you really mean you like them the best. This is a very simple example, but sometimes it can be difficult to keep things on track even with a simple mix-up like this.
If you feel your partner is wasting time talking about the good points of other cars to show you that XYZ may not be the best, just say you want to retroactively revise what you first said. Say: “I want to retroactively revise what I said. I want to change my initial statement to I very much like XYZ cars. I didn’t actually mean I like them the best of all cars; I was exaggerating, I guess.” Your partner will understand that you were using words loosely and that they need not take your original statement literally. They will change their tack and your conversation will become more in keeping with what you really think and feel.
Once learned, that technique will give both partners a lot of freedom. It’s relaxing to know you can easily change what you have said to be more in line with the thinking that has evolved in your mind since you made your initial statement.
As with most FIML techniques, FIML partners should do retroactive revisions the moment they feel that their partner may have misunderstood them. If it turns out your partner did not misunderstand, there is still a major benefit for both partners because the mistaken impression you had about your partner will not cause any further confusion for either of you.
