The BIFF Method: Brief, Informative, Friendly, Firm, and Why It's So Hard to Pull Off Live

BIFF is a response framework created by Bill Eddy at the High Conflict Institute for communicating with high-conflict people, especially exes and co-parents, without escalating the conflict. It stands for Brief, Informative, Friendly, and Firm, and it’s one of the most widely recommended tools for divorce communication. It’s also one of the hardest to actually execute in the moment, which is usually left out of the conversation.

What each part of BIFF actually means

Brief means short. You’re not writing a rebuttal, you’re writing the minimum necessary to move things forward, usually a few sentences.

Informative means you stick to facts, not opinions, not feelings, not accusations, not history. Just the information the other person actually needs.

Friendly doesn’t mean warm or affectionate, it means the tone is neutral to cordial rather than hostile or cold. A simple “Thanks for letting me know” can do the job.

Firm means the message closes the loop. It doesn’t invite an ongoing debate, and it doesn’t leave the door open for the conversation to keep spiraling.

Put together, a BIFF response gives the other person exactly what they need to know, in a tone that doesn’t hand them anything to escalate, and it ends the exchange instead of extending it.

A reactive text vs. a BIFF rewrite

Say your co-parent texts: “You’re seriously letting her miss practice again? This is a pattern with you. I don’t know why I expect anything different at this point.”

A reactive response: “It’s ONE practice. And maybe if you didn’t schedule things without checking with me first this wouldn’t keep happening. I’m so tired of you acting like I’m the only one who’s ever dropped the ball here.”

That response is long, it’s emotional, it counter-accuses, and it keeps the conflict fully open. It also all but guarantees a reply that escalates further.

A BIFF rewrite: “She’ll be at the next practice on Thursday. I’ll confirm the pickup time with you by Wednesday.”

That’s brief. It’s informative, giving the actual facts the other parent needs. It’s friendly enough in tone, no hostility, no ice. And it’s firm, it closes the exchange instead of inviting round two.

Why BIFF is hard to execute live even when you know the framework

Here’s what most explanations of BIFF leave out: knowing the four letters isn’t the hard part. The hard part is applying them in the sixty seconds after you’ve just read a message that landed like an accusation, while your body is already reacting before your brain has caught up.

Writing a BIFF response requires editing out your emotional reaction in real time, right when that reaction is at its strongest. You have to notice the urge to defend yourself, override it, notice the urge to point out their hypocrisy, override that too, and land on something short and neutral, all while your hands might genuinely be shaking.

That’s a lot to ask of anyone in the moment, and it’s exactly why so many people can explain BIFF perfectly in a calm conversation with a friend or therapist, and still send a three-paragraph reactive text the next time it actually happens. Knowing the framework and being able to execute it under real physiological stress are two different skills, and most people are never taught the second one. That gap, between understanding BIFF and actually applying it live, is the exact problem AnchorIt™ was built to close, turning a reactive draft into something brief, informative, friendly, and firm before it ever gets sent.

FAQ

Who created the BIFF method?
Bill Eddy, a lawyer, therapist, and mediator, created BIFF through his work at the High Conflict Institute, which focuses on managing communication with high-conflict individuals.

Does BIFF work over text and email, or just one?
Both. BIFF was originally developed for email but applies just as well to texts, co-parenting app messages, and any written communication with a high-conflict person.

What if the other person doesn’t respond to a BIFF message the same way?
BIFF isn’t designed to change the other person’s behavior, it’s designed to protect you from escalating the conflict yourself and to keep a clean, defensible written record if things end up in front of a court or mediator.

Is BIFF the same as gray rock?
They’re related but different. Gray rock focuses on minimizing emotional content to reduce engagement. BIFF is a full response structure that still provides necessary information, just without the friction.
