Each Trial is a strategy a real species uses, turned into something you can run yourself in about ten minutes. Each card says what to do and why it helps.
What each Trial asks you to do, and what it does for you. Reading a Trial needs no account. 3,017 Trials across 2,325 species. Showing 2,821–2,880.
The Trial
Find one place where people still relate to an old version of you, the old job, the old skill level, the old opinion, and correct it once today by stating plainly what is true now.
Why it helps
People keep treating you as the version they met because nobody ever told them otherwise. One plain correction costs a sentence and changes what you get offered for years.
2 minDifficulty 1
The Trial
Strip one setup today to only what the single hardest part of the task needs, and remove everything retained for other purposes.
Why it helps
Keeping a setup that covers every purpose means you do the hardest part with compromised tools. Stripping it to what that part needs makes the difficult bit straightforward.
2 minDifficulty 2
The Trial
Set up a deliberately different version of your routine for the season you are actually in, rather than defending the one that worked in a different season. Change at least three things and run the new version today.
Why it helps
Defending the routine that worked in a different season is why you feel like you are failing at something you used to be fine at. Building the other form openly is the thing that makes this season workable.
2 minDifficulty 1
The Trial
Let the current conditions set the form of one thing today rather than imposing a standard version, and name how different it looks.
Why it helps
Imposing one standard form regardless of conditions means it fits you badly for most of the year. Letting conditions set it means each version is right.
2 minDifficulty 2
The Trial
Carry two specialised methods today rather than one compromise, and switch between them at the boundary instead of averaging.
Why it helps
One compromise method is wrong on both sides of a boundary and you cannot tell which. Two specialised ones mean you are right on each.
2 minDifficulty 2
The Trial
Halve the cycle time on something you currently do once per period: run a smaller version today and a second one before the period ends, rather than one large attempt.
Why it helps
One long attempt per period gives you one chance to find out it was wrong, and a whole period lost. Two short ones cost you the same total and the second is informed by the first.
2 minDifficulty 2
The Trial
Name your two non-substitutable requirements today, state which of them you do not control, and secure something about that one.
Why it helps
Treating two separate requirements as one means securing the easy one and losing the other. Naming which you do not control tells you where the risk is.
2 minDifficulty 2
The Trial
Name one stop you build into a process because you assume it is required. Run the process today without that stop, and state afterwards whether anything actually broke.
Why it helps
A step you assume is required costs you time every single cycle and is often there because somebody once needed it. Running once without it tells you in an afternoon what you have been paying for.
2 minDifficulty 2
The Trial
Name one safe arrangement of yours that costs you a long commute, literal or otherwise. Make that journey today without complaint and state out loud what the distance is buying you.
Why it helps
Resenting the cost of an arrangement you chose for safety is how you talk yourself into giving the safety up. Naming what the distance buys settles whether the trade is still worth it.
2 minDifficulty 2
The Trial
Take a role you share with someone and differentiate it today so each of you is visibly doing a different job, rather than both presenting the same way.
Why it helps
Two of you presenting identically means people ask both of you everything and neither role works. Visibly different jobs halves the interruptions immediately.
2 minDifficulty 2
The Trial
Deliberately keep one thing small enough today to use a route the large versions cannot, and name the route it gives you access to.
Why it helps
Scaling something up closes the routes that made it work for you. Keeping it small is what keeps those routes open and uncontested.
2 minDifficulty 2
The Trial
Work today by frequency across a range you already know well, taking many small things rather than waiting for one that lasts.
Why it helps
Waiting for something that will last means long gaps with nothing. Many small takes across ground you know keeps you going without any of those gaps.
2 minDifficulty 2
The Trial
Concentrate all the effort for one burst today into a single specialised part and let everything else contribute nothing, with no sharing out of the work.
Why it helps
Spreading the effort across everything you have means nothing is strong enough for the moment that needs it. Putting all of it into one part gives you an actual burst.
1 minDifficulty 3
The Trial
Set up one task today as two alternating passes so that one is always working while the other resets, rather than one pass with pauses.
Why it helps
One pass with a reset between each means half your time is spent resetting and it feels like no progress. Two alternating means something is always moving forward.
2 minDifficulty 2
The Trial
Pair two of your opposite stresses today so they offset each other, scheduling one deliberately against the other.
Why it helps
Handling two opposite stresses separately means recovering from each one in turn. Pairing them means each cancels part of the other for you.
2 minDifficulty 1
The Trial
Run two opposite approaches to the same problem in parallel today rather than deciding between them, and keep both going to the end.
Why it helps
Deciding between two opposite approaches means betting everything on your guess. Running both costs you more and one of them is right.
2 minDifficulty 1
The Trial
Bring one or two others into something today specifically to attempt a target that was not possible alone, and name that target first.
Why it helps
Adding people to the same target just makes it faster. Naming a target you could not reach alone is what makes the group worth assembling.
2 minDifficulty 2
The Trial
Build one quality into the substance of something today rather than into its presentation, so it survives being broken apart or reused.
Why it helps
Quality that lives in your presentation disappears the moment someone reuses the parts. Built into the substance, it survives anything done to it.
2 minDifficulty 2
The Trial
Take something you reach only one way and establish a genuine second route to it today: a second contact, a second supplier, a second method. Use the new route once to prove it works.
Why it helps
One route to something important means one failure takes it away from you entirely. A second route tested once costs an afternoon and removes that whole category of bad day.
2 minDifficulty 2
The Trial
Take a commitment that keeps slipping and set two offset constraints on it today rather than one: a deadline and a person expecting it, a booking and a payment, a time and a place.
Why it helps
A single constraint on a slipping commitment gets renegotiated the moment it is inconvenient. Two independent ones means wriggling out of one still leaves you held.
1 minDifficulty 3
The Trial
Take something you have been guessing the direction of and take a second reading today from a different point, then state which way it is actually going.
Why it helps
One reading tells you something is happening, not where it is heading, and you fill the gap with a guess. A second reading from elsewhere settles it.
2 minDifficulty 1
The Trial
Define two distinct regimes today for your good and lean periods, and run the one that matches today rather than a compromise.
Why it helps
One compromise regime is wrong in both seasons and you never notice which. Two distinct ones mean whichever you are in actually fits.
2 minDifficulty 2
The Trial
With one other person, deliberately split a shared area by size of task rather than by topic: one takes everything small and quick, the other everything large and slow. Agree it and run it today.
Why it helps
Splitting work by topic means you both hit the same hard parts and both avoid the same tedious ones. Splitting by size of task covers far more ground and nobody is competing.
1 minDifficulty 4
The Trial
Change one signal today to suit whoever is actually available at this hour rather than repeating the one you always use, and name who it is aimed at.
Why it helps
Repeating the same message at every hour means your wording is wrong for most of the people who see it. Matching it to whoever is around gets a response the first time.
2 minDifficulty 2
The Trial
Do one routine task today standing on one foot, with your free hand holding a second point of contact rather than the wall: sorting post, washing up, making a call. Keep both contacts the whole time.
Why it helps
Relying on one point of support means a small wobble ends the task. A second contact costs you nothing and keeps you working through what would otherwise stop you.
2 minDifficulty 2
The Trial
Name the cheap strategy in your field that you consider beneath you. Describe honestly today what it actually achieves, and change one thing about your own expensive approach in response.
Why it helps
Dismissing the cheap strategy in your field means you never learn why it keeps working and you keep being undercut by it. Describing it accurately tells you which part of your expensive approach is wasted.
2 minDifficulty 2
The Trial
Pair one reduction in what you need today with one improvement in stability, so each makes the other affordable, and name both.
Why it helps
Reducing what you need without stability means the variation still breaks you. Pairing both means each one covers the other's weakness.
2 minDifficulty 1
The Trial
Take something that keeps slipping out of your control and change how you hold it today, a different method, tool or arrangement, rather than applying more attention to it.
Why it helps
Paying more attention to something that keeps slipping just means you are tired when it slips. Changing how you hold it is usually the last time it happens.
2 minDifficulty 2
The Trial
Take one thing you have been trying to deal with while it keeps moving. Fix it in place today, write it down or freeze the version, and work on the held version rather than the live one.
Why it helps
Working on something while it keeps changing means you redo the same part repeatedly and finish nothing. Freezing a version costs you a minute and makes the work actually converge.
2 minDifficulty 2
The Trial
Stand in the middle of one room and, without walking anywhere, turn slowly through a full circle twice. On the first turn name everything out of place; on the second name everything that is working. Write both lists. Only then move, and fix the single worst item.
Why it helps
Searching by walking around means you cover the same ground repeatedly and still miss things. One wide sweep from a fixed point gives you the whole picture before you spend any effort.
2 minDifficulty 1
The Trial
Take a judgement you are about to act on from your own view alone and get one genuinely different second view before you move: ask someone, measure it, look from the other side. Show your estimate, the second view, and whether the two disagreed.
Why it helps
Acting on a single viewpoint is how you miss by a consistent margin and never find out why. One genuinely independent second view before you commit catches most of those misses for the cost of a question.
2 minDifficulty 2
The Trial
Pick one thing you only know one way to get. Work out a second, completely different route to it today, and use the second route once even though the first one works.
Why it helps
Knowing one way to get something means a change in conditions takes it away from you entirely. A second route used once, while you do not need it, is the one that will still work later.
2 minDifficulty 2
The Trial
Move one activity today into a setting that removes several of its risks at once, and stop the separate measures you had for each of those risks.
Why it helps
Managing each risk with its own measure means several things for you to keep up and one of them lapses. A setting that removes several at once replaces that upkeep.
2 minDifficulty 2
The Trial
Take something you have been quietly building for months or years, a skill, a draft, a saved-up thing, and spend it today on one visible output. Show the long accumulation first, however boring it looks, then the single thing you made with it.
Why it helps
You keep adding to the store and never spend it, so the years accumulate into nothing visible. Converting the stored thing into one real output today is the only step that makes the accumulation count.
2 minDifficulty 1
The Trial
Use the protection you already have today to work in one place you had ruled out, naming the protection that makes it safe before you go.
Why it helps
You rule places out on a risk you are already protected against, and never check. Naming the protection usually opens somewhere you wanted to go anyway.
2 minDifficulty 2
The Trial
Make one committed move today in a way that cannot be undone from the other side, waiting until the thing is close enough that one attempt will do.
Why it helps
A move that can be reversed from the other side gets reversed, and you spend the week re-doing it. Waiting until one irreversible attempt will do settles it once.
1 minDifficulty 3
The Trial
Lay a sheet of green paper in a tray and bury it under a layer of rice or dry sand. Hold a hardback book in both hands with your elbows locked and clear the green using only side-to-side sweeps, moving the book forward a row after each pass.
Why it helps
A satisfying, rhythmic clearing job that shows how sweeping beats digging.
10 minDifficulty 2
The Trial
Turn scattered effort on one thing today into a single front moving in one direction, assigning each part a defined role before it starts.
Why it helps
Scattered effort means several things half-done and no part of the ground actually cleared. One front with defined roles clears it in a single pass and you see the edge move.
1 minDifficulty 3
The Trial
Find a capability already built into something you use daily but never switched on, a feature, a setting, a function, and turn it on and use it today.
Why it helps
You buy new tools while the ones you own have capabilities you have never switched on. Turning one on costs five minutes and is usually better than the thing you were about to acquire.
2 minDifficulty 1
The Trial
Let the parts of a group operate semi-independently today while keeping one shared identity, rather than coordinating every move.
Why it helps
Coordinating every move means the group covers only what you can oversee. Semi-independent parts cover far more while still counting as yours.
2 minDifficulty 2
The Trial
Take something that keeps not working and try it genuinely the other way round: the order reversed, the tool upside down, the list read bottom to top, the question asked backwards. Show the failed normal way, the inversion, and it working.
Why it helps
When something will not work you usually apply more force in the same direction. Genuinely reversing the order or orientation costs one attempt and solves a surprising share of stuck problems.
2 minDifficulty 2
The Trial
Repurpose one thing you use for moving into something that holds today, and use it to process material you could not otherwise handle.
Why it helps
Without something to hold material steady, tough things are simply off your list. One repurposed limb makes a whole category workable.
2 minDifficulty 2
The Trial
Choose a small organising job and assign one sturdy tool only to the force-heavy step while completing all ordinary steps with lighter tools or hands. Photograph the tool roles.
Why it helps
Practises role specialisation by reserving a costly force-focused resource for the narrow job its design uniquely suits.
7 minDifficulty 1
The Trial
Choose one harmless everyday task you can do in two different settings, such as writing at a desk and standing, then perform the same task once in each. Change the environment, not the tool or goal.
Why it helps
You learn which parts of your method survive a change of conditions.
8 minDifficulty 2
The Trial
Solve one ordinary problem using an obviously unusual tool or improvised extension instead of the normal tool. Keep using it until the job is actually finished.
Why it helps
The problem is solved and you stop assuming the right-looking tool is the right tool.
10 minDifficulty 2
The Trial
Find one thing you have been planning to build or set up from scratch. Today, find somebody else's finished version instead - a template, a routine, a rig, a recipe - and use it exactly as it is, without improving it. Get one real result out of their setup before you change a single thing.
Why it helps
Building your own version first is why you spend weeks before getting any result at all. Using somebody's finished setup unchanged tells you within a day whether the thing is even worth your effort.
2 minDifficulty 1
The Trial
Find the one warm place you can actually get to today and use it properly: sit there for twenty minutes rather than trying to heat the whole space, and bring whatever you need with you.
Why it helps
Trying to make everywhere comfortable means you heat the whole house and are cold in all of it. Using the one place that already works costs you nothing.
2 minDifficulty 1
The Trial
Wedge one thing against something fixed today so it is held while you work, rather than trying to hold it and work on it at once.
Why it helps
Trying to hold something steady and work on it with the same hands means doing both badly and often dropping it. Letting something fixed hold it frees you completely.
1 minDifficulty 4
The Trial
Use one borrowed form of signal today rather than your own standard one, and vary it from the version you used last time.
Why it helps
Using the same form every time means people learn to discount it and then ignore the real ones too. Varying it keeps the signal working when you genuinely need it.
1 minDifficulty 3
The Trial
Choose a safe tabletop puzzle and move one object to a higher marked point using three existing edges or surfaces for support. Keep both feet on the floor.
Why it helps
You get a concrete, memorable result while practising route flex as a real human action.
8 minDifficulty 2
The Trial
Use one capacity today that nothing in your current life demands of you: the language you no longer speak, the long run, the instrument. Give it fifteen unbroken minutes of real use, safely.
Why it helps
Letting a capacity go because nothing currently demands it means it is gone when something does. Keeping it exercised costs you minutes and keeps the option alive.
1 minDifficulty 5
The Trial
Match one thing today to the pattern of the cover you want to sit inside, changing the thing rather than looking for cover that already suits it.
Why it helps
Searching for cover that already suits you means waiting indefinitely and taking whatever is left. Changing the thing to match the cover available works this afternoon.
2 minDifficulty 2
The Trial
Close one thing completely at both ends today, and then deliberately be slower and more visible in everything else because of it.
Why it helps
Partial protection means staying quick and hidden all the time to compensate. One complete closure lets you be slow and open everywhere else.
1 minDifficulty 3
The Trial
Work out today what deficiency in your main activity one odd habit of yours is covering, and protect that habit.
Why it helps
Odd habits look like inefficiency and get cut first, including yours, and then the deficiency shows up. Naming what it covers is what keeps it safe.
2 minDifficulty 2
The Trial
Fold two sheets of paper into long arms and snip their edges into fine feathery side branches. Place a light tissue ball at one end of a table and waft it to a line at the far end, stroking with one paper arm and then the other.
Why it helps
A light, funny bit of making that turns out to need real rhythm.
12 minDifficulty 2
The Trial
Create a paper funnel leading to a marked base, place a small token there, and spend three quiet minutes observing for a naturally occurring cue before making one brief retrieval. Photograph the setup and result.
Why it helps
Practises low-cost readiness from a protected base, concentrating effort into a short action only when information arrives.
5 minDifficulty 1
The Trial
Stand or sit at one doorway, hallway corner, or path people already use, stay put for ten minutes, and only act when someone or something you need comes within reach.
Why it helps
You learn that precise placement can beat restless pursuit.
10 minDifficulty 1
The Trial
When someone is working through a space — clearing, sorting, digging, unpacking — position yourself at the far end where things come out rather than beside them, and deal with whatever emerges there.
Why it helps
A job finishes properly instead of leaving a heap at the other end that nobody owns.
12 minDifficulty 2
The Trial
Choose one small object and sit within reach of it for eight minutes while doing nothing to it.
Why it helps
You turn ambush grip into one concrete, visible experience instead of an abstract idea.
10 minDifficulty 1
The Trial
Wait for one detail today rather than looking for it: sit still in a place you know well for ten minutes doing nothing, and notice the first thing that changes without you prompting it.
Why it helps
Going out to find things means you only ever get what your search was shaped to catch. Sitting still for ten minutes shows you what you were walking past.
2 minDifficulty 1
