What conflict practice is

Conflict practice is a deliberate run-through of a difficult conversation before you have it, with a counterpart who holds the opposing position, so that you find out where you fold or flare before it costs you anything. It is not planning what to say, which you have already done, many times, usually at 2 a.m. (Why you rehearse arguments in your head →) It is saying it, out loud or in writing, to something that answers back the way the real person will.

Pilots use simulators. Litigators run moots. Surgeons practice on cadavers before they practice on you. The conversation about the equity split, the one about money, the one about whose turn it is to make the call that neither of you wants to make: those are performed cold, once, with the stakes live. Conflict practice is the simulator for them.

The practice has three parts, and most people only ever do the first:

1. A position. The thing you actually want, stated in one sentence you could say to the person's face.
2. A counterpart. Someone, or something, that takes the other side and stays there: deflects, stays reasonable while conceding nothing, says the thing that usually makes you give in.
3. A verdict. A fixed standard applied afterwards, so you learn which sentence lost you the room rather than coming away with a vague feeling that it went badly.

Without the second part you are drafting. Without the third you are venting. Both have their place. Neither is practice.

The standard: firm is not a fail

Most advice about conflict optimises for one outcome, de-escalation: soften it, lead with empathy, assume good intent. Follow that far enough and you have agreed, warmly, for years, to things you do not agree with. It looks like maturity. It compounds like debt.

The AET01 Conflict app scores conflict practice on one standard: did you stay clear, respectful and immovable? Escalating counts as a loss. So does giving in to make it stop. That is the standard Marta Morawska built the app around, and everything on this page rests on it. The standard says what the practice is for. Not winning: holding a line you have decided is yours, through the deflection, the reasonable voice, and the moment you would normally trade something important for temporary peace.

Two things make it different from the practice people usually do:

• It marks both ways of losing. Almost every tool and every coach marks aggression. Almost none marks the quiet trade: the apology that was not yours, the request withdrawn because the volume went up, the "fine, forget it" that ends the conversation and keeps the problem. AET01 Conflict scores that as a fail, because in your life it is one.
• The counterpart does not fold. A practice partner who gives way when you push teaches you that pushing works. The real person will not give way, so neither does the counterpart. Firm is not a fail; it is the point.

If you take one sentence away from this page, take this one: discomfort is not evidence of error. Most people fold at the first sign of the other person's discomfort, or their own. Practice is where you find out that you can stay in it.

The seven steps of conflict practice

1. Write the one sentence.
2. Pick the real objection.
3. Say the opening out loud.
4. Let the counterpart push.
5. Notice where you moved.
6. Replace it.
7. Stop at two minutes.

What a practice partner has to do

A practice partner for a difficult conversation has three jobs: hold the other side when you push, score you against a standard that does not move, and catch the moment you give in. Whoever or whatever you practice with, hold it to those three.

• Hold the other side. The real person will not give way when you push, so the counterpart must not either. If it concedes, you have rehearsed winning an argument nobody is going to let you win.
• Keep one standard. The verdict has to mean the same thing on Tuesday as it did on Monday, so you can see yourself getting better. A fresh opinion every session is not a score.
• Catch the fold. Giving in to make it stop is the loss almost nobody marks, because in the moment it feels kind. A partner who calls it empathy trains the exact habit you came to break.

A friend usually manages the first and misses the other two. General AI like ChatGPT, Claude, Gemini and Grok misses all three, because it is built to agree with you. Why general AI fails at practicing difficult conversations →

AET01 Conflict was built to do all three: a counterpart that holds its side at the level you choose, one standard for every session, and a verdict that names the sentence where you moved and the line that would have held. Two minutes, no account, made for partners and co-founders. The method has a name and a page: the Elenchus Method, and holdwork, the practice it trains →

Practicing the conversation with your partner

The fights couples have on repeat are rarely about the topic. Money, housework, the in-laws, the phones at dinner: the subject changes, the pattern does not, and the pattern usually includes one person going quiet to end it. That is the move to practice out of.

Conflict practice for partners is not practicing to win against them. It is practicing to say the need without the accusation, to hold it when the first response is dismissive, and to stay in the conversation past the point where you would normally leave the room or cave. How to practice the argument with your partner before you have it →

If the same fight has been running for years, use both. The pattern underneath is what couples therapy works on: practice between sessions, the cycle in them. For couples in New York City and San Francisco, sessions are online and start with a free consultation.

Practicing the conversation with your co-founder

Founding teams have three conversations they postpone longest: the one about equity, the one about one founder's performance, and the one about whether one of you still wants to be here. Each has been rehearsed alone, for months, until the version in the founder's head has become a prosecution. Said that way, it ends the partnership.

Conflict practice for co-founders is practicing the opening lines against a counterpart who will give the real answer: the deflection to process, the counter-accusation, the reasonable voice that concedes nothing. You find out whether you can say the true thing without saying it as a verdict. How to practice the co-founder conversation before you have it →

Practice is what you do before the session; the session is where the two of you have the conversation with someone whose only interest is the partnership. Aether offers co-founder coaching online, both founders present, for founding teams in San Francisco and New York City. The complete guide to co-founder conflict covers the patterns themselves.

Does practicing a difficult conversation actually work?

Yes. People who practice behave differently when it counts. In a Stanford study, everyone got the same short conflict-resolution training and half also practiced against a simulated counterpart. Then came a live conflict, with a researcher playing the other side and no idea who had practiced. The practice group used escalating tactics about two-thirds less and cooperative ones about twice as often. Role-play practice has decades of evidence behind it in medical training, negotiation teaching and assertiveness training. And the verdict is part of why it works: a 2026 study of novice counselors found that simulated practice without feedback made one skill worse, which is why AET01 Conflict names the sentence. What the research says, with the numbers →

You decide what you stand for. Practice makes sure you can say it and hold it when it counts. Nothing on this page is therapy, and conflict practice is not for crisis.

The tools, briefly

Most tools that let you practice a difficult conversation are built for work: the performance review, the salary ask, the customer complaint. They are good at that. Almost none is built for the conversation with a partner or a co-founder, and almost none scores giving in as a loss.

• A friend playing the other side. Free, available, and usually too kind to you. Ask them to be the strongest version of the other person, and to tell you the sentence where you went wrong.
• General AI like ChatGPT, Claude, Gemini or Grok. Fails as a counterpart, for the reasons above.
• Workplace practice apps and training simulators. Built for managers and L&D budgets; useful if your hard conversation is at work.
• AET01 Conflict. A difficult conversation simulator for partners and co-founders: a counterpart that holds its position at one of four levels, a two-minute session, a verdict against a fixed standard. Made by Marta Morawska at Aether. iOS and Android; coming to the App Store and Google Play.

Frequently asked questions

What is conflict practice?

Conflict practice is practicing a difficult conversation before you have it for real, against a counterpart who takes the other side and does not give way, then reviewing exactly where you escalated or gave in. It is the conversational equivalent of a flight simulator: the stakes are off, the pressure is real, and the lesson is the specific sentence that lost you the room.

What standard is a conflict practice scored against?

In AET01 Conflict, one standard: whether you stayed clear, respectful and immovable. Escalating counts as a loss, and so does giving in to make the conversation stop. Most tools and most advice mark only the first; the app marks both ways of losing and gives you the line that would have held.

Where do I start with conflict practice?

With one conversation and one sentence: write the thing you want to say, say it out loud to a counterpart who pushes back, find the sentence where you moved, and replace it. The step-by-step method is its own page: the seven steps, in full →

What is a difficult conversation simulator?

A difficult conversation simulator plays the other person in a hard conversation so you can practice it before it happens: it takes their side, pushes back, and scores how you did. Most are built for workplace training, like the performance review or the salary ask. AET01 Conflict is the difficult conversation simulator for partners and co-founders, scored on whether you stayed clear, respectful and immovable.

Can AI help me practice a hard conversation with my partner or co-founder?

Yes, when it is built to hold a position instead of to help. AET01 Conflict takes your partner's or your co-founder's side and holds it at one of four levels, then names the sentence where you moved and the line that would have held. General assistants are built to agree, so they concede the moment you push. Why general AI fails at it →

Why do I keep playing out arguments in my head?

Because the conversation matters and you have nowhere else to have it; conflict practice gives the instinct a counterpart that answers back and a verdict that is not yours. Why you rehearse arguments in your head, and what to do with it →

Is conflict practice the same as couples therapy or co-founder coaching?

No. Practice is something you do alone, before the conversation, to change how you hold a position. Couples therapy and co-founder coaching are sessions with the other person present, working on the relationship itself. Aether offers both the practice tool and the sessions, and they go together: practice between sessions, the pattern inside them.

Does practicing a difficult conversation work?

Yes; a Stanford study at CHI 2024 measured it, and the numbers are in the section above. The research in full, with the caveats →

Start with one conversation

Pick the one you have been drafting and not sending. Write the sentence. Then practice it in AET01 Conflict, which will take the other side and hold it for two minutes, and see where you move.

If the conversation is with your partner, couples therapy is the room for the pattern underneath. If it is with your co-founder, co-founder coaching is. Both start with a free 15-minute consultation.
