How Do Collaborative Problem Solving and Mini Habits Work Together?

What each one is actually for

Collaborative Problem Solving

Collaborative Problem Solving, developed by psychologist Ross Greene, starts from one claim: a kid (or adult) who repeatedly melts down, refuses, or shuts down at the same trigger point isn't choosing to misbehave — they're stuck on a specific skill or expectation gap that nobody has named yet, and the outburst is what stuck looks like from outside. The practice itself is a structured conversation, usually called Plan B. First, the adult asks about the concern from curiosity, not accusation — "I've noticed you shut the math book every time long division comes up — what's going on for you there?" — and keeps asking follow-up questions until the actual concern surfaces, which is often not what anyone guessed going in. Second, the adult states their own concern plainly: homework not getting done, a deadline, a grade. Third, and this is the step that makes it collaborative rather than a lecture, the two of them brainstorm solutions together until they land on one that actually answers both concerns, not just the adult's. You can picture doing this: pull up a chair, ask the real question, and don't propose a fix until you've heard the actual obstacle.

Mini Habits

Mini Habits, the method from Stephen Guise's book of the same name, asks you to take a habit you keep failing to sustain and shrink it down until it feels almost embarrassingly easy — not "exercise more" but one push-up, not "write every day" but one sentence, not "read more" but two pages. The size is deliberately, absurdly small: small enough that on your worst, most depleted night, you can still do it without negotiating with yourself. You do the tiny version every day, and you're allowed — but never required — to do more once you've started. The mechanism is straightforward to picture: most habits fail not because the big version is a bad idea but because willpower and motivation fluctuate night to night, and a habit sized for your best day gets skipped on your average one. Size the ask for your worst day instead, and it survives days your bigger plan never would have.

What you get out of pairing them

What Collaborative Problem Solving buys you is the end of a fight that keeps repeating for no visible reason: instead of the same standoff at the same moment every day — the same meltdown, the same refusal — you get a specific, nameable obstacle you can actually do something about, and a plan built by both people that has a real shot at holding because the person who has to follow it helped write it. What Mini Habits buys you is a way to stop the daily gamble of hoping tonight is a night you have enough motivation, because the ask has been shrunk down to something that doesn't need much motivation at all — you stop losing the habit to a bad day, because a bad day was already planned for. Together, they close two different gaps that usually get blamed on the same word — "they're just not trying" — when the actual explanation, in each case, was something specific and fixable that nobody had bothered to look for.

What Collaborative Problem Solving rests on

• Externalizing makes pattern visible randomised trials
  Putting an internal pattern into an external, structured form makes it visible and available for examination instead of remaining implicit and merely enacted.
• Parts have positive intent clinical practice
  A behavior that looks like misbehavior is usually a mistaken strategy aimed at meeting a legitimate underlying need rather than an expression of badness itself.
• Collaborative solution generation increases buy in observational studies
  Jointly generating a solution with the person who has the problem produces more durable follow-through than an imposed solution.

What Mini Habits rests on

• Small wins compound randomised trials
  Repeating a small consistent action accumulates over time into a result too large to produce in a single step.
• Lowering effort threshold increases adherence clinical practice
  Shrinking a behavior down to a brief, low-barrier unit increases how consistently people actually do it compared with committing to a larger effort.

Where they actually meet

Line up the two mechanisms and the shared move is visible: neither one starts by asking someone to simply want it more. Collaborative Problem Solving refuses to treat a repeated outburst as a willpower problem — it treats it as an unsolved, specific obstacle and goes looking for it before proposing anything. Mini Habits refuses to treat a habit that keeps failing as a willpower problem too, but it treats the size of the ask itself as the obstacle, and removes that one specific thing rather than diagnosing further. Both are doing the same underlying thing to different material: before demanding a behavior, find out what's actually standing between the person and doing it, and deal with that first.

The principle underneath both

Asking someone — including yourself — to just do the thing, when the thing keeps not happening, treats every repeated failure as the same failure: not enough effort. But a behavior that keeps not happening despite real intent is usually being blocked by something concrete: a missing skill, an unstated fear, a size of ask that outruns what a depleted evening can supply. Find and remove that specific thing, and the behavior that looked like a motivation problem often turns out not to have been one.

What that makes the real goal

If removing the actual blocking obstacle is what does the work in both practices, then the target either one is aiming at is diagnosis before demand: identify, specifically, what stands between an intention and the behavior — a skill gap, an unnamed fear, an ask sized too big for a real day — before asking for compliance with anything. That target holds whether the behavior in question is a child's homework refusal or an adult's abandoned exercise routine; the method is the same either way — find the actual obstacle, remove or shrink that one thing, then ask again.

Other practices that serve the same goal

Applied Behavior Analysis's Functional Behavior Assessment does formally, in clinical and school settings, what a Plan B conversation does informally: it observes a repeated problem behavior and works backward to the specific antecedent and consequence maintaining it, rather than treating the behavior as the thing to fix directly, and it carries a substantial clinical evidence base behind that assessment-before-intervention sequence. BJ Fogg's Tiny Habits approach reaches the same target as Mini Habits from a slightly different angle — instead of shrinking a habit and hoping motivation shows up on a low day, it attaches the tiny version to an existing routine (an "anchor") so the habit doesn't need to be remembered or willed into being at all, which some people find removes an even earlier obstacle than size alone does. And implementation intentions — the specific "when X happens, I will do Y" planning studied by psychologist Peter Gollwitzer — pursue a related target from the diagnosis side: instead of asking what's blocking a behavior after it's failed repeatedly, they pre-decide the exact trigger and response in advance, which prevents some of the same in-the-moment gaps that a Plan B conversation is often called in to repair after the fact.

A tradition that already does this

The idea of sizing a change so small it bypasses resistance predates Mini Habits by decades. Kaizen, the Japanese continuous-improvement philosophy, and its popularization for individual habits by Robert Maurer in "The Kaizen Way," explicitly recommends one-minute versions of a change — one push-up, one minute of tidying — on the reasoning that a large ask triggers a fear response that a genuinely tiny one doesn't, which is close to the same claim Guise makes about willpower. On the Collaborative Problem Solving side, the diagnose-the-real-obstacle move has a direct clinical precedent in Ross Greene's own earlier work in special education and juvenile justice settings, where "the kid is choosing to misbehave" had been the default explanation for skill deficits nobody had actually assessed — Greene's contribution was formalizing the assessment as a conversation two people could run together rather than a professional evaluation done to one person.

Running a One-Question Plan B on Your Own Stalled Habit

When a mini habit — even at its smallest size, one push-up, one sentence — still isn't happening most days, don't shrink it further. Run a short version of Plan B on yourself instead: ask, honestly and without judgment, what's actually getting in the way at the moment you skip it. Is it that you genuinely forget, which points to a cue problem rather than a size problem? Is there a specific dread attached to starting — the push-up is fine, but it's a reminder of a body you feel bad about — which points to an emotional obstacle no amount of shrinking touches? Or is it, in fact, still willpower, in which case the mini habit framework already has the right answer? The point of borrowing the CPS move here isn't to run a formal three-step conversation with yourself out loud; it's to stop assuming you already know why the habit is failing and actually ask, the way you'd ask a kid, before concluding the fix is to make it even smaller.

Shrinking the Plan You Two Just Agreed On

A Plan B conversation often ends with a solution that sounds reasonable in the room — "I'll do my math homework right after school, before anything else" — but is still too big to survive a bad afternoon, and when it fails once, the collaborative goodwill built by the conversation is at risk of collapsing with it. Before the conversation ends, run the plan through a Mini Habits-style shrink: what is the smallest possible version of this solution that could still count as a win on the worst version of that afternoon? Maybe it's not "do the homework," it's "open the math book and write your name at the top" — genuinely, almost insultingly small — with anything past that counted as a bonus, not the bar. This doesn't replace the diagnosis Plan B just did; it protects it, by making sure the agreed solution can actually survive contact with a real day instead of quietly failing and reopening the original conflict.

The Third Afternoon in a Row the Math Book Stays Shut

You've had the Plan B conversation. You know now — because you asked and actually listened — that it isn't laziness, it's that long division specifically makes your kid feel stupid in a way they can't say out loud, and the agreed plan was to start with five minutes of it right after school. Today is the third afternoon in a row the book hasn't opened at all, and the temptation is to assume the plan failed and go back to the old argument. Instead, you shrink it the way Mini Habits would: not five minutes of long division, but opening the book and writing today's date at the top of the page — nothing about doing a single problem. Your kid does that in eleven seconds and, having done it, does one problem anyway, unprompted, because the actual barrier was never the workload; it was the size of the first step relative to how defeated they already felt walking in the door. You didn't need a new diagnosis. You needed the size of the ask to match the size of what was left in the tank that specific afternoon.

When this is worth reaching for

A chore or routine has already failed more than once despite a plan that sounded reasonable on paper — 'just try harder' didn't hold, and neither did 'just make it smaller' tried alone. It also applies heading into a stretch where someone's baseline capacity is already lower than usual — a hard school term, a rough patch at work — because that's exactly when a hidden obstacle and depleted willpower tend to show up at the same time.

Where this does not apply

If a behavior is failing for a reason that's already fully known and named — a kid has openly said the chore feels unfair, an adult has openly said they hate running — running a full Plan B conversation to rediscover what's already on the table wastes a step that doesn't need repeating; go straight to negotiating the actual disagreement or shrinking the actual ask. And if the obstacle Plan B genuinely surfaces is a real skill deficit — a kid who can't yet do long division at all, not one who feels defeated by it — shrinking the task doesn't touch a missing skill; a smaller version of a problem nobody knows how to solve is still a problem nobody knows how to solve, and what's needed there is instruction, not a smaller ask.

What the evidence does and does not support

Collaborative Problem Solving has a real clinical evidence base behind it: Ross Greene and colleagues have published outcome studies, mostly in school and inpatient psychiatric settings, showing reductions in disciplinary incidents and restraint use when staff are trained in the Plan B approach, though the research is largely observational and program-evaluation in design rather than large randomized trials, and results vary by how faithfully a school actually implements it. Mini Habits' evidence is thinner and more indirect: the broader research on self-efficacy and on lowering the effort required to start a behavior — some of it randomized — supports the underlying claim that a smaller first step gets attempted more often, but Stephen Guise's specific technique, as a packaged method, rests mainly on his own account and reader testimonials rather than a trial of the method itself. Nobody has studied running a Plan B-style diagnosis and a Mini Habits-style shrink together as a combined sequence; that they'd help each other, in the ways described above, is a reasonable inference from what each is independently good at, not a measured finding.
