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 1,681–1,740.
The Trial
Before acting on your next assumption about what is wrong, spend ten minutes locating it precisely: measure, ask, check the log. Only act once you can state exactly where the problem is.
Why it helps
Acting on roughly where you think the problem is means fixing the wrong thing and doing it twice. Ten minutes locating it precisely is what turns most attempts into first-time fixes.
2 minDifficulty 2
The Trial
Hold one position today where what you want is delivered past you rather than going out after it, and take it the instant it is within reach. If it is out of reach, do not reach.
Why it helps
Reaching for things that are out of range means you miss and give away your position. Waiting until it is genuinely within reach makes nearly every attempt land.
1 minDifficulty 4
The Trial
Name the overlap for one thing today, the window where it is both worth doing and safe to do, and act only inside it rather than when it occurs to you.
Why it helps
Acting whenever something occurs to you means paying full cost in the worst conditions. Waiting for the window where it is both worth it and safe costs you only patience.
2 minDifficulty 1
The Trial
Name one thing of yours that only works under particular conditions. Check whether those conditions are present today, and if they are not, withdraw and wait rather than attempting it anyway.
Why it helps
Attempting something in the wrong conditions burns your energy and teaches you the thing does not work, which is the wrong lesson. Withdrawing and waiting costs you a day and keeps the method intact.
2 minDifficulty 1
The Trial
Look at a group you are part of and identify who is genuinely most exposed, then direct the available protection to that person today rather than spreading it evenly.
Why it helps
Spreading protection evenly means the exposed person still has too little and everyone else has more than they need. Directing it costs you nothing and actually prevents the failure.
2 minDifficulty 2
The Trial
Cut what you expose about one thing today down to the single part that has to be visible, and put the rest genuinely out of sight.
Why it helps
Showing more of something than the job requires gives everyone a surface to pick at and you spend your time defending it. Exposing one part cuts that to nothing.
2 minDifficulty 1
The Trial
Expose only the part of you that gathers information today and keep everything else out of reach, acting from the anchored position.
Why it helps
Exposing all of yourself to gather information means all of you is reachable. Showing only the sensing part gets you the same information safely.
2 minDifficulty 1
The Trial
Let only one small deliberate thing move today while everything else about your position stays completely still.
Why it helps
Moving several things at once means you are visible and nothing is persuasive. One moving element against total stillness is what draws attention in.
2 minDifficulty 1
The Trial
Sit in water, a bath or a pool, with only your head above the surface for five minutes, keeping completely still and letting your body stay heavy rather than floating. Keep someone within earshot.
Why it helps
Showing all of yourself in every situation means people respond to the display rather than the work. Keeping most of it below the surface lets you act before you are read.
2 minDifficulty 1
The Trial
Rehearse one joint routine today outside the season you actually need it, so it still works when you do.
Why it helps
Only practising a joint routine when you need it means it fails the first time under pressure. Rehearsing in the quiet season costs you minutes.
2 minDifficulty 2
The Trial
Define the exact reach you are working within today, in time or scope. Take everything that falls inside it and decline everything that would need you to extend, even if it looks better.
Why it helps
Stretching for the nearly-reachable thing is how you end up overcommitted on something you never had the room for. A defined reach means everything you take is something you can actually finish.
1 minDifficulty 3
The Trial
Line up five foods that each need opening in a different way, such as a boiled egg to crack and peel, an orange to peel, a yoghurt pot to pierce, a jar to loosen by tapping the lid, and a kiwi to scoop. Open all five using only the teaspoon and your hands.
Why it helps
A quick exercise in improvising with what you have.
10 minDifficulty 2
The Trial
Move one task today onto ground that suits how you work rather than adjusting how you work to where you are, and name what the new ground gives you.
Why it helps
Bending the way you work to suit wherever you happen to be means doing your weakest version constantly. Moving the task to suitable ground makes your ordinary way effective.
2 minDifficulty 2
The Trial
Instead of pursuing a decision from someone today, create the opening and let them step into it: the blank slot in the calendar, the unfinished sentence, the question left hanging. Make the space and wait.
Why it helps
Chasing a decision makes people defensive and slower. Creating a clean opening and leaving it there gets the same decision without you spending anything on the chase.
2 minDifficulty 1
The Trial
Take something you have been waiting to become easier and open it today in its current difficult state, using whatever tool makes that possible.
Why it helps
Waiting for something to get easier means arriving with everyone else who waited. Opening it while it is still hard means you are the only one there.
2 minDifficulty 2
The Trial
Open one closed thing today by working along its own seam and twisting, with no crushing or general force applied anywhere else.
Why it helps
Forcing something open ruins what was inside, which was the only reason you opened it. Working along its own seam takes you slightly longer and leaves the contents whole.
2 minDifficulty 3
The Trial
Take a job where you got access but never extracted the value, the file you can now open, the person who said yes, the room you got into, and bring the second tool today: the questions, the export, the actual ask. Finish the second half.
Why it helps
Getting access feels like the win, so you never extract anything and the access goes stale. Bringing the second tool is usually twenty minutes and it is the only part that produces a result.
2 minDifficulty 2
The Trial
Pick one unfamiliar harmless object or mechanism and test three different ways of understanding how it works before looking anything up. Explain what you learned at the end.
Why it helps
You understand one object properly instead of assuming, which transfers to every similar mechanism.
10 minDifficulty 2
The Trial
Pick one stubborn everyday container, knot or package that genuinely needs opening and work on it patiently instead of forcing it. Continue until it opens.
Why it helps
The stubborn thing opens and stays usable, instead of opening and being ruined.
10 minDifficulty 1
The Trial
Identify one resource you repeatedly need and make access easier now by opening, preparing, bookmarking, or placing it ready for next use.
Why it helps
One thing you reach for constantly stops costing you thirty seconds every time.
6 minDifficulty 2
The Trial
Choose one disposable or already-broken object and take it apart against a five-minute timer to discover how it was assembled. Lay the pieces out when time ends.
Why it helps
Turns destructive curiosity into practical understanding of how everyday objects are constructed.
15 minDifficulty 4
The Trial
Take something faint you keep missing and widen the receiving surface today: add two more sources, ask two more people, check two more places. Not look harder, look wider.
Why it helps
Concentrating harder on the same few sources does not help you catch a faint signal. Two more sources costs almost nothing and is what actually makes it detectable.
1 minDifficulty 4
The Trial
Take something you keep backing out of to re-plan and instead make the adjustment today without withdrawing: change it in place, mid-flow, without starting over.
Why it helps
Backing out to re-plan every time means you restart constantly and finish nothing. Adjusting in place keeps the progress you already made.
2 minDifficulty 2
The Trial
Find an archive, backlog or store you have never been able to use and get into it today with a precise method rather than brute effort: the search, the converter, the index, the single query.
Why it helps
A store you cannot get into is dead weight you keep paying to carry. One precise way in turns years of accumulation into something you can actually use.
2 minDifficulty 1
The Trial
Choose three safe peelable or split packages such as pistachios or wrapped portions and open all three using the same narrow blunt tool to start each opening.
Why it helps
You turn shell skill into one concrete experience with a visible finish.
10 minDifficulty 2
The Trial
Have a helper put a small wrapped sweet or coin in each of two plastic screw-top jars, close them and put each jar in its own cloth bag or pillowcase. Put one hand in each bag and work both lids off at the same time, then bring both prizes out.
Why it helps
A strange, satisfying puzzle for your hands that shows how much they can do without your eyes.
10 minDifficulty 3
The Trial
Pick one opportunity you keep taking partial bites at. Wait today until it is fully in front of you, then take the whole thing in one action rather than a piece of it.
Why it helps
Taking repeated partial bites at something warns it and leaves you with fragments that are worth less than the whole. Waiting and taking all of it once gets you the thing you actually wanted.
1 minDifficulty 3
The Trial
Identify today the distant and earlier signal that actually drives your local conditions, and start tracking that instead of local ones.
Why it helps
Watching local conditions means reacting after they have already changed. Finding the upstream signal gives you weeks of warning for nothing.
2 minDifficulty 2
The Trial
Make one small enclosed shelter for an object or a pet — a box, a cloth dome, a nook — and orient its opening deliberately for the current season, away from sun in summer or toward it in winter. Say which way and why.
Why it helps
You learn that the direction a shelter faces does more work than what it is made of.
15 minDifficulty 2
The Trial
Take one thing you communicate for your own small group today and make it accurate and clear enough for a stranger to act on, then put it where a stranger could actually find it.
Why it helps
Writing only for the people in the room means everything you produce dies when the room changes, and you rewrite it each time. Making it usable by a stranger costs one pass and keeps working without you.
2 minDifficulty 2
The Trial
Choose one thing you have been avoiding because the full version is too exposing - a hard conversation, a public post, a room you stopped going into. Do the smallest version that still counts, with your exit already arranged: ten minutes, one topic, a stated time you leave. Go in, do that much, and leave on time.
Why it helps
Avoiding something entirely keeps the fear intact, and forcing the full version usually ends badly enough to confirm it. A short exposure with a guaranteed exit lets you find out it is survivable.
2 minDifficulty 2
The Trial
Make several wide trips today for one purpose and end every single one at the same fixed point, rather than stopping wherever each trip happens to finish.
Why it helps
Letting each trip end wherever it finishes scatters what you gathered and you lose track of it. Ending all of them at one point means the range costs you nothing extra.
2 minDifficulty 2
The Trial
Name the place you go to take things in - a city, a shop, a library, a gym - and the place you go to make things. Today use both: spend at least half an hour gathering in the first, then come back to the second and actually make or finish something with what you gathered.
Why it helps
Trying to gather and produce in the same place is why you do neither well and feel stuck. Separating the two into different rooms or trips makes both of them noticeably easier.
2 minDifficulty 2
The Trial
Work today in the hours your target is actually reachable, even though everyone in your field works the opposite ones.
Why it helps
Working your field's conventional hours means your target is out of reach for most of them. Matching its availability is the whole difference.
2 minDifficulty 2
The Trial
Instead of arguing for your approach against the established one, produce three small instances of it today and put them where people will see them. Make no case for it at all.
Why it helps
Arguing for your approach invites everyone to argue back, and the incumbent always wins that. Three visible instances settle it without a discussion.
2 minDifficulty 1
The Trial
Time your contribution today to overlap with others saying the same thing, so the combined reach exceeds what any of you has alone.
Why it helps
Speaking in your own window means your reach is capped at your own volume. Overlapping with others carries far beyond anything you could manage.
1 minDifficulty 4
The Trial
Overlap the contributions of a group today in a coordinated sequence rather than having everyone speak at once or in turn.
Why it helps
Everyone speaking at once is noise and strict turns take all day. Coordinated overlap carries far further than either and costs you no extra time.
2 minDifficulty 3
The Trial
Change something internal today so you can stay where you are through a hard period, rather than relocating for it.
Why it helps
Relocating for every hard period means you never settle anywhere and it costs you the move. One internal change lets you sit it out where you are.
2 minDifficulty 1
The Trial
Choose a corner of a room with a clear floor. Carry soft things to it one item per trip: cushions, a blanket, pillows, a towel. Use no more than twelve items. Arrange them into a covered nook, with a blanket draped over the top and a single way in. Then crawl inside and sit there for one minute.
Why it helps
A calm corner you built yourself is easier to return to than one you keep meaning to buy. Small trips add up quickly, and you end with a real place to rest, read or think.
2 minDifficulty 1
The Trial
Choose one short, important task you face tomorrow: an exam, a match, a presentation, a trip. Tonight, gather every item it needs into one bag or one spot by the door, checking each against a list as it goes in. Leave nothing to fetch in the morning.
Why it helps
Big mornings go wrong over small missing things. Packing everything the night before means your energy on the day goes into the task itself, not into hunting for a charger or a form.
2 minDifficulty 1
The Trial
Dig a narrow vertical tunnel in a deep pot or tub of damp sand or soil. Divide a lump of modelling clay into four balls, press one bead into the centre of each, roll each ball in the soil, then push all four down the tunnel and fill it in.
Why it helps
A muddy, satisfying build with a buried treasure you can dig up later.
20 minDifficulty 2
The Trial
Pack a daypack or school bag for tomorrow with everything inside it. Nothing strapped to the outside, nothing poking above the zip, and the heaviest items packed closest to your back. Then put it on and walk twenty steps.
Why it helps
A bag with things hanging off it snags, swings and tires your shoulders. Packing everything inside, with nothing sticking out, stops the snagging and swinging and leaves your hands free for the day.
2 minDifficulty 1
The Trial
Gather at least six things you would want on a freezing night or in a winter power cut, such as a torch, spare batteries, gloves, a hat, a blanket and a long-life snack. Test the torch and read the snack's best-before date, then pack everything into one open box labelled for the cold, ready to put where you can reach it quickly.
Why it helps
One less thing to scramble for when the weather turns.
15 minDifficulty 2
The Trial
Collect five non-perishable snacks, put them in a box or bag, label it with a date to check it, and tuck it into a drawer, cupboard or bag pocket where it will not be raided by accident.
Why it helps
A small store that saves a hungry, rushed moment later.
8 minDifficulty 1
The Trial
Tear half a small cabbage into pieces by hand, massage them with about one teaspoon of salt per 250 grams until they wilt and weep, then pack them tightly into a clean jar until the brine covers the leaves. Weigh them down and loosely lid the jar; keep the leaves under the brine and discard the batch if fuzzy mould or a bad smell appears.
Why it helps
Your own sauerkraut in a couple of weeks, from one cabbage and some salt.
20 minDifficulty 1
The Trial
Before finalising something today, fill it as completely as you can, then close it and work only with what is inside.
Why it helps
Closing something half-filled and planning to add later means you never do and you work short. Filling it first costs the same hours and you keep all of it.
2 minDifficulty 1
The Trial
Take one thing of yours that is currently spread out and exposed. Bring all of it into a single unwatched place today, packed together, and leave it there.
Why it helps
Things of yours spread across visible places each lose a little to attention and interference until none of them is intact. Pulling them into one unwatched place stops the leak immediately.
2 minDifficulty 1
The Trial
After a meal, spoon every leftover into clean pots or boxes with lids and seal them. Label each with the food and today's date, and stack them together in the fridge.
Why it helps
Tomorrow's lunch sorted and less food in the bin.
10 minDifficulty 1
The Trial
Before your next long outing, put two snacks that carry their own water, such as cucumber sticks, orange segments, grapes or melon, into a sealed box. Pack them before you leave the house, not on the way, and put the box in your bag.
Why it helps
Long afternoons out often end early because you get thirsty and tired at the same moment. Packing food that also hydrates you keeps your energy steady when there is nowhere to buy a drink.
2 minDifficulty 1
The Trial
Spend the effort once today building one thing into something so it needs no ongoing input, and cancel the recurring effort it replaces.
Why it helps
Anything that needs topping up will lapse during the week you are busiest. Paying once in the build means it keeps working whether you get round to it or not.
2 minDifficulty 2
The Trial
Cover the top of a small box with paper or fabric in the same pattern as your floor or rug. Paint or stick a row of bright blue spots low along its sides only, then put it on that floor.
Why it helps
A tiny build that shows how where you put a signal decides who sees it.
20 minDifficulty 2
The Trial
On a sunny day when the paving feels warm to the hand, put two ice cubes from the same tray into two identical bottle caps. Set one cap directly on the paving and tape the other to the top of a stick pushed upright nearby so it sits 30 to 50 cm up in the same sun, then wait ten minutes.
Why it helps
A small outdoor experiment that makes heat you can feel visible.
15 minDifficulty 1
The Trial
Name precisely where your protection on something stops today, and prepare the specific escape for everything beyond that line.
Why it helps
Assuming your protection covers everything is how you sit still through the thing it does not cover. Naming the limit tells you what to prepare for.
2 minDifficulty 1
The Trial
Gather something quickly today without processing it on the spot, then take it somewhere safe and go through it a second time properly.
Why it helps
Processing things where you gathered them keeps you exposed for hours and you do it badly. Gathering fast and going through it properly later gets both.
2 minDifficulty 1
The Trial
From across a room or through a window, get one person to carry out a real small task using only hand gestures. No words, no writing and no phones.
Why it helps
You end up with a handful of gestures that genuinely work across a noisy room.
5 minDifficulty 2
The Trial
Tape rolled sheets of paper or card tubes end to end into a tunnel at least one metre long, running from a pile of ten dry stems (dried grass, straw or uncooked spaghetti) to an upturned box with a doorway cut in its side, and raise the pile end on a stack of books so the gallery slopes gently down to the box. Break each stem to fit, then feed them into the top of the tunnel one at a time so they slide down, nudging any that stick along with the next stem or with a thin cane longer than the gallery, until all ten lie inside the box.
Why it helps
A satisfying little build that turns scrap paper into a working tunnel.
15 minDifficulty 2
The Trial
Take something one person in your group is carrying alone that is plainly too heavy, and take a share of it today without being asked. Tell them you have it.
Why it helps
Waiting to be asked means the person carrying it has to admit they cannot, which they will not do in front of you. Taking a share unasked and saying so is the only version that actually lifts it.
2 minDifficulty 2
The Trial
Keep pressing one thing today that you would normally drop after the first refusal: ask again, follow it to the next person, stay with it until it moves or the day ends. Do not escalate, just continue.
Why it helps
Dropping things at the first refusal means you only ever get what people say yes to immediately. Simply continuing, without any confrontation, gets you most of the rest.
1 minDifficulty 4
The Trial
Blow up a small balloon and mix flour and water into a smooth paste. Lay five complete layers of torn paper strips over it, one at a time, each painted with paste over the last and alternating newspaper with plain or coloured paper so every layer can be told apart, leaving one fingertip-sized hole uncovered at the top.
Why it helps
A calm, messy craft that leaves you with a shell to paint once it dries.
20 minDifficulty 1
The Trial
On a breezy or cold day, hold a thin strip of tissue close to the edges of every window and outside door in your home that you can reach standing on the floor, working round in one planned circuit; no climbing on chairs, sills, stools or ladders. Stick a small note on each edge where the strip flutters, and finish back where you started.
Why it helps
You find out exactly where your home is losing heat, ready to fix.
