Using Collaborative Problem Solving to enhance 25/5 Rule
And how 25/5 Rule sharpens Collaborative Problem Solving in return.
Collaborative Problem Solving, developed by psychologist Ross Greene and often taught through a sequence he calls Plan B, has an adult and a child jointly figure out the specific unsolved problem behind a behavioral outburst, rather than the adult assuming the child is simply being defiant, and then generate a solution together that actually addresses it. The 25/5 Rule, commonly attributed to Warren Buffett, has a person write twenty-five career or life goals, circle only the top five, and treat the other twenty as an avoid-at-all-costs list rather than a someday list. On this reading, both refuse to act on an assumption, about why a child is struggling or about what a person's real priorities are, until it's written down and examined; and both then apply real discipline to what the writing reveals, addressing one problem at a time in one case, eliminating twenty goals in the other. Held together, Collaborative Problem Solving can teach the 25/5 Rule how to handle the goals that keep resurfacing despite being on the avoid list, and the 25/5 Rule can teach Collaborative Problem Solving's users how to choose which unsolved problem to tackle first.
What each one is actually for
Collaborative Problem Solving
Collaborative Problem Solving runs on a specific three-step sequence Greene calls Plan B. First, the empathy step: the adult asks open, genuinely curious questions to find out what's actually hard about the moment for the child, not why they're misbehaving, but what specifically makes finishing this particular homework, or getting on this particular bus, difficult right now. Second, the adult states their own concern plainly, the thing that also has to be true for a solution to work. Third, the two of them brainstorm together until they land on something both can actually live with, rather than the adult imposing a consequence or the child getting their way by default. The method's premise is that a behavior that looks like defiance is almost always a mistaken strategy for handling a real, specific difficulty the child hasn't been able to name yet.
25/5 Rule
The 25/5 Rule has a person write out twenty-five things they want to achieve, in a career or in life more broadly, then circle only the top five. What makes it more than a priority ranking is what happens to the other twenty: rather than filing them as a someday list to return to once the top five are handled, the practice is to treat them as actively off-limits, things to say no to on purpose, on the reasoning that a genuinely good goal sitting at number eleven is more dangerous to the top five than an obviously bad idea would be, because it's tempting enough to quietly pull attention and effort away from what was supposed to matter most.
What you get out of pairing them
What Collaborative Problem Solving buys is a solution that actually holds, because it addresses the real difficulty instead of suppressing the visible behavior; a child who complies out of fear of punishment hasn't had their actual problem solved and it tends to resurface somewhere else. What the 25/5 Rule buys is protection for a person's best hours from being quietly drained by goals that are individually reasonable but collectively make the top five impossible, the twenty aren't distractions in the usual sense, they're plausible enough to keep earning attention they shouldn't get. Together, the underlying payoff is the same kind of relief: not having to guess, moment to moment, what's actually driving a behavior or what's actually worth your time, because both have already been named, specifically, in writing, ahead of the moment that would otherwise force a rushed decision.
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 25/5 Rule rests on
-
Constraint increases follow through
observational studies
Fixing the set of allowed choices in advance, before the moment of decision, produces more consistent follow-through than deciding in the moment.
-
Cognitive load limits effective goal count
observational studies
Pursuing too many goals at once dilutes attention and reduces the odds of succeeding at any single one.
-
Prioritization by elimination focuses effort
practitioner report
Actively identifying and avoiding lower-priority items rather than merely ranking them protects attention and resources for the top few.
Where they actually meet
Both practices start by refusing to act on the story that's already in your head, that the child is being defiant, that all twenty-five goals matter roughly equally, and force that story onto paper or into a conversation where it can actually be examined. Collaborative Problem Solving externalizes a child's hidden concern through the empathy step's specific questions; the 25/5 Rule externalizes an adult's real priorities through the physical act of writing all twenty-five down before circling any. Where they meet is in what each does after the externalizing: neither stops at simply seeing the pattern more clearly. Greene's method commits to solving one unsolved problem at a time rather than every friction point simultaneously; the 25/5 Rule commits to actively excluding, not just deprioritizing, everything outside the top five. Naming the thing is only step one in both; the harder second step is choosing what not to address right now.
The principle underneath both
Naming what's actually driving a behavior or a set of ambitions, in specific, concrete terms rather than a vague impression, is what makes it possible to choose, deliberately, what to act on and what to set aside. A parent guessing at a child's motive, or a person carrying an unranked mental list of everything they'd like to achieve, both end up reacting to whatever feels most urgent in the moment, which is rarely the same as what actually matters most. Specificity is what turns a reactive default into a real choice.
What that makes the real goal
If naming precedes choosing, the objective both practices are actually built for is turning an implicit, unexamined driver, a child's hidden concern, a person's blurred set of ambitions, into an explicit, negotiated commitment that can be acted on and revisited, rather than something that just gets reacted to as it comes up. That objective doesn't belong to child behavior or to career planning specifically; it's the general move of replacing a guess with a stated, examined choice.
Other practices that serve the same goal
Nonviolent Communication's needs-naming step, identifying the specific unmet need underneath a demand or a complaint rather than arguing with the demand itself, chases the same objective as Greene's empathy step, applied to adult relationships instead of a parent and child, with a smaller but real observational evidence base in conflict-reduction settings. The Eisenhower Matrix, which sorts tasks by urgency and importance into four quadrants and explicitly flags a fourth quadrant, urgent-but-not-important, as delegate-or-eliminate, pursues the same elimination logic as the 25/5 Rule's bottom twenty, with wide anecdotal use in time-management practice but little controlled research isolating the matrix itself as the active ingredient.
A tradition that already does this
Motivational Interviewing, developed by Miller and Rollnick primarily for behavior change around substance use, already fuses both moves into a single well-studied method. A clinician using it first elicits the client's own stated reasons and concerns, structurally similar to Greene's empathy step, and then works with the client to narrow to one or two specific, achievable goals rather than an open-ended list of everything that should change, structurally similar to the 25/5 Rule's circle of five. It's a real precedent, with a substantial randomized-trial base, for treating 'find the real driver, then ruthlessly narrow the target' as one coherent method rather than two separate ones.
Using Collaborative Problem Solving to enhance the 25/5 Rule
The 25/5 Rule tells you to actively avoid the bottom twenty goals, but it doesn't tell you what to do when one of them keeps resurfacing anyway, when you catch yourself, three weeks in, quietly making progress on goal number fourteen despite having crossed it off. Collaborative Problem Solving's empathy step gives you a way to handle that resurgence instead of just gritting your teeth harder. Rather than treating the relapse as a discipline failure, run Greene's first move on yourself: get specifically curious about what's actually pulling you toward that goal right now, not why you're being undisciplined, but what real concern, boredom with the top five's current phase, a genuine fear the fourteenth goal represents, is driving the pull. Often the honest answer reveals either that the fourteenth goal is meeting a need none of the top five currently address, in which case it may deserve a real conversation about swapping it in, or that the pull is avoidance of something hard in the top five, in which case naming that plainly is more useful than another round of willpower.
Using the 25/5 Rule to enhance Collaborative Problem Solving
Greene's own method already warns against trying to run Plan B on every friction point at once, but in practice, a parent or teacher facing a child with several recurring unsolved problems, homework, bedtime, transitions between activities, often tries to address all of them simultaneously and ends up with no bandwidth to run the empathy step properly on any single one. The 25/5 Rule's discipline transfers directly here. List every specific unsolved problem you can currently name, it's rarely fewer than eight or ten once you actually write them out, then circle only the one or two you'll actively work on this month through full Plan B conversations, and explicitly, out loud with any co-parent or co-teacher involved, agree the rest are being set aside for now rather than ignored. The explicit naming matters as much as it does in the original 25/5 Rule: an unaddressed problem that's been consciously tabled behaves differently than one nobody agreed to postpone.
Tuesday evening, the homework fight that's really about something else
It's Tuesday and your eight-year-old is refusing, again, to start his reading log, and you notice this is the fourth different recurring friction point you're currently trying to manage with him, reading log, bedtime stalling, backpack packing, morning transitions, and you've been running some version of Plan B on all four this week with no real progress on any. You sit down that evening and, instead of one more empathy conversation on reading logs alone, you write all four out on paper, plainly, the way a 25/5 list gets built. You circle one: bedtime stalling, because it's affecting his sleep and everything else downstream of it. You tell him directly, in words he can follow, that reading logs and backpacks are getting a pass for the next few weeks while you two work on bedtime together. The relief is immediate and mutual: he's not being pursued on four fronts, and you finally have the actual attention Plan B's empathy step requires to ask him, specifically and without rushing to the next fire, what makes lying down at bedtime hard for him right now.
When this is worth reaching for
A parent, teacher, or coach is facing several recurring behavioral friction points at once and running out of bandwidth to do the empathy step properly on any of them. The second case is for anyone using the 25/5 Rule whose excluded goals keep resurfacing in a way that pure willpower isn't resolving.
Where this does not apply
If there's genuinely only one unsolved problem in play, a single specific behavior, a single clear goal, the elimination half of the 25/5 Rule has nothing to prune; there's no list to cut down. And imposing the 25/5 Rule's exclusion logic onto a child unilaterally, deciding on your own which of their struggles get attention this month without the collaborative naming Greene's method requires, would violate the entire premise of Collaborative Problem Solving; the elimination has to be negotiated and explained to the child, not just applied to them the way an adult applies it to their own goal list.
What the evidence does and does not support
Collaborative Problem Solving has a real, if modest, randomized-trial base specifically for reducing challenging behavior in children with behavioral or developmental difficulties, which is more than most parenting frameworks can claim. The 'parts have positive intent' idea behind it, that misbehavior is usually a mistaken strategy for a legitimate need, rests more on clinical theory and case observation than on trials isolating that specific belief as the active ingredient. The 25/5 Rule's evidence is thinner still: its origin as a Warren Buffett anecdote is disputed by biographers who can't confirm the story happened as told, and its two supporting ideas, that too many goals dilute effort and that active elimination beats passive deprioritizing, rest on general research about goal conflict and attention rather than a trial of this exact technique. Nobody has studied prioritizing which unsolved child-behavior problems to tackle using a 25/5-style elimination list; that combination is this page's own extension of two separately grounded ideas.
