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.
Trials drawn from real behaviour
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 1,861–1,920.
Pile cushions on a blanket on a clear floor or lawn, and have three or more people stand in front of it facing the same finish mark and point at it. Then each holds the blanket edge behind them and everyone walks forwards together at walking pace, never backwards, until the blanket crosses the mark in a straight line.
Why it helps
A silly, cooperative few minutes that shows how much faster a group moves once it agrees first.
Before the next bad stretch, seal in one thing from the current good one to carry across: the cooked meals, the drafted messages, the prepared answers. Put it aside sealed today.
Why it helps
Arriving at a bad stretch with nothing stored means you handle it at your worst with nothing to draw on. One sealed thing prepared while you were fine makes the whole gap survivable.
3Pulse it open to the marks ten times in ten seconds
4Stand up slowly and rest a minute
The Trial
Skip this if you have high blood pressure, glaucoma or vertigo, or are pregnant. Put two tape marks on a clear floor about eighty centimetres apart, stand over them with feet apart and fold forward so your head hangs below your hips, holding any cloth or scarf by its top corners; on a timer, pulse it open until each lower corner touches a tape mark and back until the corners meet, ten full pulses in ten seconds with one low, mechanical-sounding hum, and any pulse that misses a mark or a broken hum resets the count to zero. Stand up slowly after each attempt, rest standing for at least a minute before another, and sit down if you feel dizzy.
Why it helps
A short, ridiculous, genuinely hard rhythm challenge that shakes off stiffness.
Hold one internal standard constant today regardless of the environment you move through, and cross between two settings that normally exclude each other.
Why it helps
Letting your standards match each environment means you cannot move between them without becoming someone else. Holding them constant lets you cross freely.
Draw a twenty-centimetre circle on a sheet of paper. You and a consenting rival each fit a red balloon to a hand pump and, on go, pump until your balloon is as wide as the circle, then hold it up beside the paper.
At the next meal today where you are present with other people, serve everyone else fully before you take anything at all, and make at least one person's portion ready to eat in their hands rather than on the table. Only sit down and eat once everybody else has started.
Why it helps
Taking your share first is normal and it is also why the people around you feel like an afterthought. Serving everyone before yourself once shows you how little it actually costs you.
3A smaller room, a fixed deadline, a written reply
The Trial
Take something that keeps slipping away from you and move it today into the setting where it has fewest escape routes: the smaller room, the fixed deadline, the written reply.
Why it helps
Chasing something across open ground where it has every option is why it keeps slipping. Moving it somewhere narrow means it resolves without you being any quicker.
Take a task on messy ground where you keep getting caught on small obstacles and do it in a few big committed pushes today rather than continuous small progress.
Why it helps
Grinding continuously through messy ground means catching on every small obstacle and stopping constantly. A few large committed pushes clear them and you arrive with less total effort.
Take a situation with nothing obvious to grab onto and create your own purchase by pressing against both sides: contact two people, use two constraints against each other, set a deadline and a commitment. Make the hold today.
Why it helps
Waiting for an obvious handhold in a situation that has none is how you stay at the bottom. Pressing two real things against each other makes a grip where none existed.
Use one tool or method you already have for both the heaviest and the most delicate task on your list today, rather than switching between separate ones.
Why it helps
Switching tools between heavy and delicate work costs you the setup each time and you lose the thread. One instrument that does both keeps you in flow.
Use a piece of soft modelling clay or similar safe material and push three drinking straws through it from the inside-facing side until their tips emerge.
Why it helps
You turn internal defense into one concrete experience with a visible finish.
Give the next review or critique an obvious focal point away from the part that matters: the open question up front, the deliberate placeholder, the section you flag for feedback.
Why it helps
Presenting something with no obvious focal point means reviewers pick their own, usually the part you most need left alone. Offering one genuine focus directs the attention safely.
Name one reserve you have run down and not replaced - sleep, savings, a friendship, a stocked cupboard. Today, put something back into exactly that reserve, not a different one: an early night, a transfer, a visit, a shop. One deposit, made today, into the thing you actually drained.
Why it helps
Running a reserve down and then never refilling it is how you end up with nothing to draw on and no idea when that happened. One deliberate deposit today starts reversing it.
1Pick something you went through but didn't absorb
2Go through it a second time
3Look only for what you missed
The Trial
Take something you went through once and did not absorb, the book, the meeting notes, the course, the document, and go through it a second time today looking only for what you missed.
Why it helps
One pass through anything leaves most of it unabsorbed, which is why you remember so little of what you read. A second pass costs a fraction of the first and is where the value actually lands.
Name the good conditions you are in right now, however small. Use today to add something that will only be useful later, and keep your existing safety arrangement in place while you do.
Why it helps
Spending good conditions on enjoying them leaves you entering the hard season with nothing added. Building something now that only pays later is the only use of a good stretch you cannot make up afterwards.
Take one piece of information, help or credit you were going to pass along generally. Deliver it today to the single specific person or place where it can actually be acted on, and to nobody else.
Why it helps
Passing good information along generally feels generous and almost always lands somewhere that cannot use it. Delivering it to the one place that can act turns your same effort into an actual result.
Name one boundary of yours that people keep crossing because you have to enforce it each time. Build the consequence into the situation itself today so it happens automatically, and stop enforcing it by hand.
Why it helps
A boundary you have to enforce every time costs you a confrontation each round and gets crossed anyway. Building the consequence into the situation means it holds whether you are paying attention or not.
Put one deliberately imperfect, clearly-labelled thing at the edge of your work today so attention lands there rather than on the core: the open question, the known gap, the marked draft section.
Why it helps
When you present something apparently flawless, people hunt for the flaw and find it in the middle. Marking a real gap at the edge means the attention lands somewhere you can afford.
Move the exposed part of something you are doing today so that what is at risk is something you can afford to lose: the version, the budget, the slot, not the whole thing.
Why it helps
Exposing the part you cannot lose is how one knock takes the whole thing out. Moving the risk onto something expendable means a hit costs you almost nothing.
Stand still with eyes closed and both arms held out in front. Within five minutes, a helper chooses a moment and walks slowly past trailing a scarf that brushes your hands; grasp it on contact.
Why it helps
A few minutes of calm stillness with a small jolt of reaction at the end.
Pick one thing you have been approaching loudly and from the front - an ask, a correction, a sale. Today use the ground instead: arrive by the quiet route, get genuinely close before you say anything, and then make the whole ask in one go with nothing held back.
Why it helps
Announcing an ask from a distance gives people time to prepare a no, which is why yours keep failing. Getting close quietly and then asking once, completely, changes the odds enormously.
1Set a biscuit in a strainer over a bowl, spoon ready
2On go, crush it through with the back of the spoon
3First to hold up an empty strainer wins the round
The Trial
You and a consenting rival each set one hard biscuit or cracker in a tea strainer over a bowl, spoon in hand. When a third person or a random phone timer calls "go", both scrape and crush your biscuit with the back of the spoon, and the first to hold up an empty strainer over a bowl of powder wins; play best of three.
Why it helps
A loud, crumb-flinging contest that also leaves you a bowl of crumb topping.
Pour equal glasses of water and a thick drink that suits you, such as a smoothie, milkshake or plant-based shake thin enough to pass a standard straw. Drink each through the same straw at a steady comfortable pace, timing both, then compare the two times.
Why it helps
A snack, a drink and a physical memory of why thick blood is a problem.
When a timer, doorbell, message ping, or kitchen timer sounds, race on foot indoors to that signal source and claim the spot with a clear hand-on-target within seconds.
Why it helps
You train fast detection-to-action when a short window opens.
With another person, choose two target sets of clearly different sizes and race simultaneously, each using the set that suits their reach or throwing style. Swap once and compare.
Why it helps
You get a concrete, memorable result while practising layered value as a real human action.
Take a small amount from several sources today rather than everything from one: ask three people briefly instead of one at length, sample three datasets, visit three suppliers.
Why it helps
Taking everything from one source exhausts the person or the data and they resist you next time. Small amounts from several gets you more in total and nobody minds.
In a baking tray, build a mound from no more than twelve pebbles or stones about the size of a walnut and set a scrunched ball of tissue on top as your egg. When it is finished, start a timer in view, pour iced water into the tray around it until the water is 3 cm deep, then leave it untouched for ten minutes.
Why it helps
A quick engineering puzzle that makes you think about building with a limited supply.
In your next disagreement, present the information plainly and then stop rather than pressing: state your position, state what it rests on, and say nothing more until they respond.
Why it helps
Pressing after you have made your point makes people defend rather than consider it. Stating it once and stopping is uncomfortable for ten seconds and settles far more encounters.
Change how one thing reads today in an instant without moving it or adding anything, using only what it already has.
Why it helps
Needing to move or add something to change how a situation reads means you cannot do it when you are pinned. A change using what is already there works from where you stand.
Pick somewhere people genuinely lose each other, a shop, a park, a busy room, and put up a marker anyone in your group can spot from distance: a raised bright item, a hat held high, a chosen meeting post. Show the crowded view, then the marker, then someone actually finding you by it.
Why it helps
You assume the people looking for you can see you, and then you all waste twenty minutes. One visible marker above the crowd does what a dozen messages cannot, and it keeps a group together.
Wrap bright tape or draw bold yellow and black bands on the undersides of both forearms. Rest your arms palm-down on a table, run a random-interval timer app or have a helper clap at random, and on each cue snap both forearms up to show the bands.
Why it helps
A fast reaction game with a striking visual payoff.
Count fifty sesame seeds and scatter them over a clean, dry, coarse-bristled mat, rug offcut or upturned scrubbing-brush head. Tape your thumb loosely against your palm with a strip of masking tape, then scrape and rake the seeds out of the bristles with your four fingers and sweep them into a cup.
Why it helps
A calm, fiddly task that shows how much a hand can still do without its thumb.
Cloud a wide, shallow tray of water with a splash of milk so you cannot see the bottom. Stand with your back to the tray, wearing headphones playing music, while a consenting helper drops one effervescent vitamin tablet at a random spot, then turn when they tap your shoulder and rake a tea strainer, no wider than a quarter of the tray, once through the spot where bubbles are breaking the surface; repeat for three tablets, and pour the water away afterwards rather than drinking it.
Why it helps
A quick, tricky game that shows how much a surface can tell you about what is hidden beneath it.
In a garden, park or large cleared room, at least four people including the caller spread out and wander apart. At unpredictable moments, one person gives a loud rolling call and everyone jogs or walks fast, not sprinting, to regroup around the caller within ten seconds, slowing before contact and then closing up shoulder to shoulder. Do three rounds with a different caller each time.
Why it helps
A lively group game that shows how fast a single clear signal can move people.
2Five minutes: wipe the densest patch with damp cloths
3Until that patch is visibly cleaner
The Trial
Recruit at least one other person. In a five-minute burst, wipe soft insect clusters or mildew spots from one heavily affected houseplant or outdoor patio plant using damp cloths only. Work the densest patch first until that local outbreak is visibly reduced.
Why it helps
You learn to swarm the worst spot first instead of dabbling evenly across a whole area.
Pick one fixed base today, work only within the distance you can get back from, and return and settle there before conditions change.
Why it helps
Ranging further than you can get back from is how you lose the base everything else depends on. Keeping each move inside returning distance costs you reach and keeps your hold.
The night before, freeze about two centimetres of water in a plastic tub. Wearing gloves, work at one spot in the middle of the slab with a metal teaspoon, scraping and turning until a hole goes all the way through, wide enough to push a finger through.
Why it helps
A cold-handed, strangely meditative challenge that makes the effort of keeping access open feel real.
Lie or sit covered by a blanket up to your eyes, holding a comb and a piece of corrugated card or a ridged bottle beneath it. Make a loud, steady rasp for ten seconds by drawing the ridged surfaces across each other, keeping your head completely still.
Why it helps
A calm, funny way to make a signal with the smallest possible movement.
Source one structural input today separately from your normal supply, because your normal supply does not contain it, and name both.
Why it helps
Assuming your normal supply contains everything you are built from means a slow structural shortfall you never diagnose. Sourcing it separately fixes it.
Make one boundary audible today before it is reached: say the limit out loud, early, in plain words, to the person most likely to cross it, and do nothing else about it.
Why it helps
Letting people discover your limits by crossing them means every limit costs you something to hold. Saying it out loud early means most of them are never tested.
Before the next time you would push back on someone, state the warning plainly and early instead: say exactly what you will do and at what point, then wait and give them the chance to stop.
Why it helps
Escalating without warning makes enemies out of people who would have backed off, and costs you more than the dispute was worth. A clear early warning usually ends it for you.
Cut ten long paper feathers, stick a circle of foil or glossy paper near each tip, and tape the bases together into an upright fan. Hold the base and shake it in short fast shivers so the feathers rattle audibly and the eyespots flicker.
Why it helps
A bright, noisy make that is surprisingly fun to show off.
There is somewhere you cannot go but need something from. Instead of forcing access, build the reach: the specific question, the long tool, the one contact inside, the narrow request. Use it to get what you needed today.
Why it helps
Waiting for full access to a room, system or group means waiting indefinitely. A narrow reach usually gets you the one thing you actually needed, today, without the permission.
Use one counterweight today to reach further than you safely could otherwise: hold something behind you, brace with the other arm, shift your mass deliberately, and reach the thing you would normally fetch a chair for.
Why it helps
Stretching past your balance means you either miss or fall, and you stop trying. A deliberate counterweight extends what you can reach without risking either.
Take one container packed with something you need a few items from - a drawer, a fridge shelf, a bag, a dense lettuce. Get five specific items out using only your fingers, without emptying it, tipping it or taking anything else out. Put nothing back differently from how you found it.
Why it helps
Tipping everything out to find one thing is why your drawers, fridge and bags stay chaotic and you lose twenty minutes each time. Reaching in precisely keeps the order you already have.
Instead of putting yourself somewhere risky to get something today, extend your reach from where you are safely standing: the longer tool, the intermediary, the request made from here.
Why it helps
Stepping somewhere unstable to reach something is how one small gain costs you everything. Extending your reach from safe ground gets the same thing with none of that.
Identify the one thing you can reach that the people around you cannot, a contact, a permission or a level of access. Use it today on something that has been stuck, and do not spend it on the easy work.
Why it helps
Spending your unusual access on ordinary work wastes the only thing about you nobody can copy. Using it on something genuinely stuck is where it produces something nobody else could have.
Something you need is in another place and you have been planning to go there. Get it without moving: call, order, ask, screen-share, request it sent. Stay where you are and extend to it instead.
Why it helps
Travelling to get something costs you the whole surrounding hour. Extending to it instead usually works first time, and you keep the state you were already in.
Pick one tool you own that extends your reach - tongs, a grabber, a long spoon, a ladder. Use only that tool to collect five things you need today without moving your body to them. Then pass something on from each pickup: give one of the five away, or leave it somewhere useful to someone else.
Why it helps
Extending your reach usually means taking more for yourself, which is why people stop handing you things. Pairing every reach with something passed on keeps the supply coming back to you.
3Draw the object in with something that extends you
The Trial
Put something just out of reach, then get it without moving your feet from a taped mark. Use whatever extends you: an arm, a broom, a hook, a belt. Show the mark, show your feet staying on it, show the object arriving.
Why it helps
Rearranging your whole situation to get one thing is usually the expensive option. Finding the bit of you that can extend instead gets the same result without paying to move everything.
