This book was recommended to me by a colleague who is a lawyer and an academic. I have been working on "bureaucrat" speak for some time and finding that people respond better to it. I do this because when I put my heart and soul into a response with a genuine attempt to provide learning opportunities for students, for example, the message is rarely received the way it was intended. As Eddy suggests, the proportion of high conflict personalities (HCPs) is on the increase, and my experience supports the notion. The BIFF approach works and works well. While the approach is similar the bureaucrat patter I have developed, the BIFF approach gives one a definite framework in how to structure responses to high conflict people and "blame-stormers". With BIFF on my mind when responding to HCPs, I am reducing the number of my unnecessarily emotive responses to inappropriate or rude emails. The approach works. I am not a fan of this genre, but I would be lying if I said it wasn't helpful. If you correspond with large numbers of people, get this book and read it. It will save you time and energy and reduce the unnecessary stress created by HCPs.

This is very good information and helpful for anyone dealing with a high-conflict person in pretty much any context. Putting this technique into practice will require a LOT of practice and it would be very helpful, as the author notes, to have someone review written responses to help you fine-tune them. Honestly, I don't think I could keep my cool in a face-to-face situation well enough to use this formula, but in written formats, it's definitely well worth practicing.

This is a great book for coming up with responses for High Conflict People (HCP). The response technique for an HCP is Brief, Informative, Friendly, and Firm (BIFF). I really enjoyed the examples, and the specifics to managing an HCP attack. I appreciate how the BIFF response is meant to get a person from survival mode into a more logical mind. This book applies to anyone involved in any sort of a dispute, including family, neighbors, business associates, politicians, relationships, association boards, organizations, etc.
The book was recently published in 2011, but even then foretold how there would be more HCP people in the future. I would suggest this book to anyone who wants to be a leader, take control of themselves, be respectable, mindful, and community oriented.

Simple short book with a very simple concept, the way to reduce conflict is to change your response to high conflict people. Lots of good examples from work and personal situations. The author's strategy: BIFF (Brief, Informative, Friendly, Firm).

This was very helpful to me. I'm trying to learn how to deal with my husband's ex-wife who is very hostile in person and email. This book opened my eyes to things I didn't realize.

Practical advice, similar to what public schools are now using for email and social media etiquette "THINK" - Thoughtful, helpful, important, necessary, kind"...and I like to add 'call'

Bill Eddy is a lawyer and conflict mediator; I previously read his 2021 book BIFF at Work: Your Guide to Difficult Workplace Communication (see my review here) which is a practical guide to BIFF (brief, informative, friendly, and firm) communications in professional settings that I found to be quite helpful. Eddy's 2011 book BIFF appears to be the first book in his series (which also includes books like BIFF for CoParent Communication: Your Guide to Difficult Texts, Emails, and Social Media Posts and BIFF for Lawyers and Law Offices: Your Guide to Respectful, Written Communication). This was a quick read that's relatively light on practical examples -- the feature that I found so helpful in BIFF at Work, hence my lower rating here.
I will say there is quite a social media niche of advice gurus who specialize in exploring people with narcissism and the other DSM cluster B personality disorders (antisocial, borderline, and histrionic) -- how to recognize them, how to manage and/or cope with them, how to cut them out of your life, etc., that this book and several of Eddy's other books lean heavily into, with the framing of BIFF as a strategy for "high conflict people". I'm not a proponent of armchair diagnoses so I don't find this angle particularly helpful, but I do think BIFF at its core is a good tactic to effectively deal with high conflict situations.
My statistics:
Book 134 for 2025
Book 2060 cumulatively

You’re going to encounter high-conflict people sooner or later. They’re the ones who who seem to thrive on fights and arguments, who blame others, and frame themselves as innocent victims. Getting into a tangle with a high-conflict person wastes time and energy, and it can damage your professional and personal relationships. You need to be ready. Bill Eddy’s short book is full of practical tips and strategies on how to deal with such people, and not let the conflict spiral out of control.
BIFF stands for brief, informative, friendly, and firm. In Bill Eddy’s view, that’s the essence of any response to a high-conflict person, and you can tell he knows what he’s talking about.
Bill Eddy does not spend much time analyzing the difference between various personality disorders such as narcissistic, borderline, histrionic, paranoid, anti-social, etc. He uses just one catch-all concept: High Conflict People, or HCPs for short. This is brilliant, because when you’re faced with, say, a hostile co-worker who is sending nasty emails about you to the entire workplace, it doesn’t matter what her actual personality problem is. She’s high-conflict, and the strategies you’ll need to diffuse the situation are the same no matter the exact diagnosis.
But there is more to this book than BIFF. For example, in Chapter 3, he goes into detail about why it’s important to avoid the three A’s: Admonishments, Advice and Apologies. This is going to be hard for some readers, especially if you’re a fixer who has learned to solve other people’s problems by giving advice. Or you might be the kind who apologizes at the drop of a hat, even when it’s not your fault, just to smooth things over and escape the tension of the moment. Bill Eddy talks about why the three A’s make things worse in the long run, not better.
One of the most valuable parts of the book (which alone makes it worth the price) is how to deal with suicide threats. We’ve all been taught to treat every single suicide threat as an emergency in which you drop everything and run to the rescue. But what if the same individual has made the same threat repeatedly? How do you walk the line between taking the threat seriously, and not burning yourself out by rescuing them all the time? On pp. 64-66, Bill Eddy outlines some of the most common-sense advice on this topic I’ve seen so far.
Another useful point he makes is that emotions are contagious, and intense emotions are intensely contagious. Knowing this fact can help you stay clear-headed, especially if you have to deal with highly emotional people who want to off-load their negative emotions onto you so that they feel better.
I highly recommend this book. It’ll give you conflict-resolution skills that could save you a lot of grief and trouble.

Wow this is an interesting and informative book that provides guidance on how to communicate effectively with difficult people, particularly those with high-conflict personalities (HCPs). The concept of BIFF stands for *Brief, Informative, Friendly, and Firm* responses.
The key important of this book focuses on teaching readers how to respond to hostile or abusive emails, texts, and social media posts in a way that maintains their dignity and doesn't escalate the situation. The author provides numerous examples of BIFF responses to help readers understand how to apply this concept in real-life situations.
The key takeaway from "BIFF" is that by being brief, informative, friendly, and firm in your responses, you can de-escalate conflicts and improve communication with difficult people. This approach can be applied in various contexts, including personal and professional relationships.
It's worth noting that there are different versions of the "BIFF" book, including one specifically focused on co-parenting communication.

Best book for dealing with high conflict people
The best responses are brief informative friendly and firm. As an attorney, and to deal with challenging folks occasionally and this little book has changed my responses for the better. I have sometimes struggled to respond to people who seem to just love conflict for the sake of it (not just having a different point of view that we can discuss logically). I don’t want to get down in the mud with them (unpleasant and unproductive) and yet I need to advocate for my client or myself (I can’t just ignore them). BIFF is a very practical system and it seems to be working to resolve issues with high conflict people.

An extremely accessible overview of how to deal with high-conflict people, with lots of specific examples that can potentially be used as scripts and adapted for different topics and/or audiences. Much of this is intuitive, and perhaps something one develops an instinct for over time and with experience. This book would likely build almost anyone's skills and confidence.

A very interesting method of dealing with and responding to conflicts with people in a variety of situations. Agree with a lot of the thoughts and concepts, there are a few things that are a bit more complicated, such as not apologizing, but there is some logic behind his reasoning. Will be trying yo use this approach in some of my personal and professional life.

I’m a fan!
This book helped me tremendously. It helped me realise that I used email communication in highly conflictual situations in a suboptimal manner.
I shared with my husband and ended up buying many other titles of Bill Eddy’s.
You get real advice with examples that are readily implementable.
Indispensable in anyone’s library.

EXCELLENT, easy read on guidelines for communicating with “high conflict people,” with examples running from business to political to personal. Highly recommended for someone with a dramatic person in their life, or someone who deals with many people. 👍🏼👍🏼

This has some useful strategies for dealing with high conflict people, i.e. people who seem to make every issue a referendum on *them*. Not that there are any people we know of who are like that, haha. It covers a broad variety of relationships, from marriage to chance encounters to the workplace. There is bound to be some situations that resonate for you, while others will not.
It was useful, but I am still looking for a book that both describes skillful means for dealing with narcissists, borderlines, and rageaholics and helps the reader develop a greater sense of self esteem to be comfortable doing so. Maybe that's what therapy is for...

Goes on too long with some of the examples (I get it already), but the content is aces. Highly recommended for better and briefed communication with anyone. But particularly with people you're having trouble getting along with, for whatever reason.

Basically the author found his "Love Languages" formula and processes short books on how to write passive/aggressive emails. I found this very useful for dealing with a few difficult people YOU KNOW WHO YOU ARE.

I discovered Bill Eddy on a podcast, and have gone on to listen to many podcasts on his channel, and most recently I listened to this book! It was brief and clearly written. I found it extremely helpful and have already used it in a few texts. 🙂

Good but a bit repetitive
I liked the method and will put it in practice. Found it a bit repetitive and long, but all are good examples.

Easy and useful information to take it. I liked the fact they went over a large number of examples to get it into my head the considerations for the use of the biff responses.
