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 1,021–1,080.
The Trial
Give or lend one small useful item to someone who needs it and explain in one sentence why you chose it.
Why it helps
Strengthens practical generosity and turns an ordinary possession into immediate social value.
5 minDifficulty 1
The Trial
Take something you keep knocking, snagging or losing and attach a deliberate sacrificial part to it: a loop of ribbon, a tag, a cheap strap. Show the thing bare first. Then show the decoy taking the snag or the pull instead of the object.
Why it helps
You protect valuable things by being careful, which fails the moment you are tired. Building in a cheap part that takes the damage means the loss lands somewhere you do not mind.
2 minDifficulty 1
The Trial
Multiply the surface area through which something reaches you today rather than increasing your effort to pull it in.
Why it helps
Working harder to pull in a thin input exhausts you and barely changes the total. Multiplying the surface it arrives through does it passively.
2 minDifficulty 1
The Trial
Decide in advance today which part of one thing you will give up without resisting, then give it up when pressed and withdraw the rest.
Why it helps
Resisting every loss means you fight hardest over whatever is grabbed first, which is rarely what matters. Deciding beforehand what you will drop keeps the core intact.
2 minDifficulty 2
The Trial
Give up one form of coasting today, the easy cruise, the passive stretch, in exchange for reaching something nobody around you can reach.
Why it helps
Keeping the ability to coast caps how deep you can go in anything. Giving it up is uncomfortable and puts you somewhere with no competition.
1 minDifficulty 3
The Trial
Identify the service or role people still come to you for that you have outgrown, and hand it to someone else today so you can do the wider work instead.
Why it helps
Staying available for the thing people already associate with you is comfortable and quietly caps what you do next. Handing it on properly frees the time and nobody is left stuck.
2 minDifficulty 2
The Trial
Cancel one trip, meeting or errand today and put the time directly into producing something instead. Signal clearly where you are and let whoever needs you come to you.
Why it helps
Travel and meetings quietly consume the hours you would have made something in. One cancellation put straight into output usually produces more than the trip would have.
2 minDifficulty 1
The Trial
Identify the single constraint keeping people out of somewhere you want to work, solve only that today, and then go there.
Why it helps
Avoiding places because of one constraint means competing where everyone else is. Solving just that one puts you somewhere with nobody in it.
1 minDifficulty 3
The Trial
Straight after a meal has been cooked at home, before anything is thrown away, go through what the cooking left: half onions, herb stalks, a spare egg, the end of a loaf, unused sauce. Gather everything still good to eat into one container, label it with today's date, and put it in the fridge for tomorrow.
Why it helps
A lot of what you need is already sitting behind work that has just finished. Collecting it before it is binned saves you money and gives you a head start on tomorrow without extra effort.
2 minDifficulty 1
The Trial
Tape two straws in an X, stretch a tissue or napkin taut across their four ends and add a paper clip at the front as a head weight. Set a low stack of books, its top lower than the table, at least one metre from the table edge, then release the model from the table top from an open hand with no throwing motion so it glides down and lands on or against the stack, adjusting weight and tension between tries.
Why it helps
A tiny engineering project that makes gliding physics make sense.
15 minDifficulty 2
The Trial
Pick one thing you are waiting for that has no date - a reply, an opening, a result. Today, cut what the waiting costs you to as near nothing as you can: turn off the checking, remove the reminders, move the thing out of sight, and set one single date to look again. Then carry on with the rest of your day.
Why it helps
Waiting with the checking switched on costs you more than the thing is worth, every day, and changes nothing. Cutting the cost to zero gives you the same outcome and your attention back.
2 minDifficulty 1
The Trial
Dress in dark clothes, tape a palm-size square of foil to the front of your top and set a torch or phone light on a table aimed at you in an otherwise dark room. On go, sweep your arms up into a circle and swing your upper body side to side so the foil flashes in the beam ten times in ten seconds.
Why it helps
A dramatic, funny burst of dance that feels like a stage moment.
4 minDifficulty 3
The Trial
Find the thing in your environment you routinely walk past because it is unfamiliar, a machine, a shop, a group, a feature of an app, and go and investigate it properly today. Use it, open it, ask about it.
Why it helps
The unfamiliar things you walk past every day are mostly free and useful, and the only thing keeping you out is that you have never looked. One investigation usually opens something you will use for years.
2 minDifficulty 2
The Trial
Change one setting twice today to match different parts of the day rather than leaving it fixed: brightness, noise, pace, layers. Make both changes deliberately.
Why it helps
A setting fixed for the whole day is wrong for most of it and you stop noticing. Two deliberate changes cost seconds and the day stops working against you.
2 minDifficulty 2
The Trial
Take something you normally bring back to your own desk or system and go and do it where it already lives instead: at their desk, in the room, on their machine, at the site.
Why it helps
Bringing things back to your own setup adds a round trip and a translation step to every job. Going to where it lives usually halves the time and removes the misunderstandings.
2 minDifficulty 1
The Trial
Go deeper into one position today rather than travelling to find better conditions, and name the months the surface stays impossible.
Why it helps
Travelling to find better conditions when the whole surface is bad means arriving somewhere equally bad, tired. Going deeper where you are costs one day.
2 minDifficulty 2
The Trial
Take one pressure you would normally respond to by moving elsewhere. Instead, go deeper into where you already are today, work further into the detail of it, and do not relocate at all.
Why it helps
Responding to pressure by moving somewhere else means you arrive with the same problem and no accumulated ground. Going deeper where you are is the only move that also makes you harder to reach.
2 minDifficulty 2
The Trial
Make one small audible claim today on something you hold, and then make it again, rather than relying on having claimed it before.
Why it helps
Assuming people remember your claim is how you find someone else in your space. Two cheap repetitions cost you minutes and that never happens.
2 minDifficulty 2
The Trial
For twenty minutes, stop optional posting, messaging, talking, and entertainment while remaining reachable for anything genuinely necessary. Use the time for a normal quiet activity.
Why it helps
You create a short recovery period from social output and notice what your attention does when you stop broadcasting.
20 minDifficulty 1
The Trial
Abandon one fixed route today and go instead to wherever the conditions have actually appeared, checking before you move.
Why it helps
A fixed route takes you where conditions were last year. Checking and going where they actually are is why you end up with ground nobody else worked.
2 minDifficulty 2
The Trial
Go today to where what you need is being concentrated by something contracting, rather than to where there is most of it overall.
Why it helps
Going where there is most of something means it is spread too thin for you to reach. Where it is being squeezed into less space is where you can take it.
2 minDifficulty 2
The Trial
Name one thing of yours currently buried under something you cannot shift. Instead of digging today, move to the exposed version of the same thing, the smaller or harsher place where it is already accessible, and take it there.
Why it helps
Digging at the buried version of something costs you the whole winter and usually fails. Taking the harsher, exposed version gets you less of it and gets it now, which is the difference between eating and not.
2 minDifficulty 2
The Trial
On a flat, obstacle-free loop such as an open lawn or a large clear room (not a shared path), set one easy-peel mandarin or clementine in a bowl on the loop, pick it up as you walk past without stopping, then peel and eat it at a slow walk, chewing each segment before the next. Peel goes into a small bag clipped to your belt or pocket.
Why it helps
A calm, unhurried snack and a short walk in the same few minutes.
8 minDifficulty 1
The Trial
Lie or crouch still behind a sofa or low box at the edge of a clear floor. Within a sixty-second window a helper rolls a soft ball past at a moment of their choosing; lunge out once and clamp it with both hands.
Why it helps
A sharp jolt of reaction speed and a lot of laughter.
3 minDifficulty 3
The Trial
Choose one soft target object, stand still for exactly ten seconds, then grab it in one sudden committed movement. No false starts.
Why it helps
Trains the contrast between patience and decisive action instead of constant half-commitment.
15 minDifficulty 4
The Trial
Have someone place a known target object somewhere in a safe cleared room, then turn the lights off. Find it and grab it as fast as you can in the dark, with no torch.
Why it helps
A short sharp burst that shows how quickly your eyes actually adapt.
3 minDifficulty 3
The Trial
Make a small cardboard flap over a tabletop opening. From behind it, lift the flap, grab one nearby token and pull it back behind the flap in one quick motion.
Why it helps
You turn hidden strategy into one concrete, visible experience instead of an abstract idea.
5 minDifficulty 3
The Trial
Scatter forty dried beans over a patch of floor and kneel beside it with a cup. A consenting helper lays a blue towel as the flood at one side and slowly slides it across the beans, then draws it back and pushes it forward again at their own pace; pick beans only from the strip within one hand-width of the towel's edge, moving with the line, until twenty are in your cup.
Why it helps
A quick, surprisingly absorbing game about keeping up with a boundary that will not stay still.
10 minDifficulty 2
The Trial
Build tolerance today for the distance between where you work and where you resupply, rather than trying to move them closer together.
Why it helps
Trying to move your work and your resupply closer together usually fails and costs the attempt. Building tolerance for the gap makes both usable as they are.
2 minDifficulty 2
Amazonian Manatee · RivergentleThe Trial
Identify the abundance you currently have that will not last, time, access or goodwill. Use a large deliberate amount of it today rather than rationing it, and record how much you took.
Why it helps
Rationing an abundance that is going to disappear means you lose most of it unused and still feel short. Taking a large amount now converts it into something that lasts past the window.
2 minDifficulty 2
The Trial
Fill a small bowl with young, tender greens that are safe raw, such as pea shoots, cress, microgreens or lightly cooked asparagus tips, and sit alone by a window about fifteen minutes after sunset with a clock in view. Eat slowly for fifteen minutes, so that the bowl is finished as the sky outside turns visibly darker.
Why it helps
A calm, green meal that slows the end of the day down.
20 minDifficulty 1
The Trial
Lay a blanket as the meadow near your burrow and set on it one platter of bite-sized raw greens and vegetables, such as lettuce, pea shoots, cucumber, carrot sticks and cherry tomatoes, a small portion for each person. With at least two other consenting people, eat from the platter in three two-minute bouts on a timer, and between bouts everyone stops and lies back or sits still for one minute to bask; the platter must be cleared by the end of the third bout.
Why it helps
A shared plate of greens and a funny, relaxed rhythm of eating and resting together.
12 minDifficulty 2
The Trial
Mark a square of garden or park grass about three steps on each side with four stones and set one bowl of cut raw vegetables and greens in the middle. In the early morning, everyone sits inside the square and eats from the shared bowl until it is empty, then the whole group gets up together and lies down in the nearest shade; in the late afternoon, reverse it, lying up in the shade together first and then eating in the square as the day cools.
Why it helps
A slow shared snack outdoors at the gentlest time of day, and a lie-down together afterwards.
15 minDifficulty 2
The Trial
In your own garden or an allotment where you may pick, sit tucked against a patch of an edible plant big enough to screen you on at least two sides, such as raspberry canes, a pea row or a large mint or lemon balm clump, facing out toward open ground. Without standing up, pick and eat a small snack of berries, pea pods or leaves from the parts within arm's reach, rinsing them first from a water bottle.
Why it helps
A calm, sheltered snack straight from the plant, eaten where no one can see you.
12 minDifficulty 1
The Trial
Name one thing you value that quietly degrades when unused, a skill, a route or a relationship. Use it today in the ordinary way it is meant to be used, not in a special or ceremonial version.
Why it helps
Things you value but leave alone close over, and by the time you want them back the cost of reopening is far higher than using them would have been. Ordinary use is the whole maintenance.
2 minDifficulty 1
The Trial
Identify a thin, widespread resource around you that nobody bothers with, discarded material, unread records or spare minutes. Harvest a real amount of it today and show what the amount came to.
Why it helps
Looking for resources that look like resources puts you in competition for all of them. The thin layer everyone walks past is unclaimed, and the only cost to you is the equipment to use it.
2 minDifficulty 2
The Trial
Choose the activity you most reliably overrun on today. Before you start, decide the hard stop - a clock time or a count, written down. Work it, stop exactly there even if it is going well, and then do nothing demanding for twenty minutes: no screen, no decisions, flat on your back if you can.
Why it helps
Pushing a good session until you are empty costs you the next day, and you never get that back cheaply. Stopping on a written limit and actually recovering means tomorrow starts at full capacity.
2 minDifficulty 3
The Trial
Match how you present to the setting you are working in today, so that being there openly draws no attention, and then work alongside others in it.
Why it helps
Standing out in a setting means every move you make is examined. Matching it lets you work openly in the same space without any of that.
2 minDifficulty 2
The Trial
Take something you usually forward on untouched and process it properly instead today: read it fully, extract the point, discard the rest. Forward nothing until you have the content.
Why it helps
Forwarding things unread makes you a relay and you get nothing from anything passing through. Grinding one properly gives you the content and usually means you never need to forward it.
2 minDifficulty 1
The Trial
Take something you keep losing hold of partway through and add one gripping mechanism today, a written commitment, a recurring slot, a second person, so it cannot slide away.
Why it helps
Things you lose hold of halfway are not a speed problem, and trying harder has not worked. One gripping mechanism means it finishes without your diligence.
2 minDifficulty 1
The Trial
Take a problem you have been handling in general and identify the single part that actually causes the harm, then control only that: the one clause, the one person, the one setting. Leave everything else alone.
Why it helps
Tackling a problem as a whole is how it stays unsolved for months. Finding the one part that actually does the damage usually takes you an afternoon to control, and the rest stops mattering.
1 minDifficulty 3
The Trial
Start one unsustainable push today only after confirming the window is open, rather than beginning it early and running out.
Why it helps
Starting an unsustainable push before the window opens means you are spent when it does. Confirming it first is the difference between everything and nothing.
1 minDifficulty 4
The Trial
Walk slowly along the route from your bed to the door and pick up every object on the floor along it, one at a time, putting each away where it belongs. Finish by straightening any rug edge or cable so the route is continuous and clear.
Why it helps
A safer walk to the door in the dark, tonight and after.
10 minDifficulty 1
The Trial
Lay a favourite jacket out flat in good light. Lint-roll or brush every panel, pick off bobbles, straighten the collar and cuffs, and tighten or re-sew any loose button, then hang it up smooth.
Why it helps
A calm, satisfying care routine that leaves you with a ready-to-wear favourite.
15 minDifficulty 1
The Trial
Pick one thing today you have been trying to detect directly and set up instead to detect the disturbance it causes, and stop looking for the thing itself.
Why it helps
Watching for the thing itself in conditions that will never show it means you find out afterwards, every time. Watching for the disturbance it causes tells you now.
2 minDifficulty 2
The Trial
Name the condition one of your methods silently depends on today, check whether it still holds, and state what you would do if it stopped.
Why it helps
Not knowing what your way of working quietly depends on means you discover it the week the thing disappears. Naming it now costs you ten minutes.
2 minDifficulty 2
The Trial
Choose deliberately today which other group you work alongside rather than joining whatever is largest, and name why that one and not another.
Why it helps
Joining whatever group is biggest means you get the numbers and know nobody in them. Choosing which to associate with gets you the same reach with people who know you.
2 minDifficulty 2
The Trial
Add one costly protection today only after identifying the specific signal that it is needed, and leave it off everywhere that signal is absent.
Why it helps
Protecting against everything everywhere costs you speed on all of it for a risk that is mostly absent. Adding it where the signal appears keeps you quick elsewhere.
2 minDifficulty 2
The Trial
Choose today to invest in growth and deliberately skip holding any ground, or the reverse, rather than attempting both.
Why it helps
Trying to grow and hold ground at once means doing both slowly and losing the ground anyway. Choosing one gets you much further on it.
2 minDifficulty 2
The Trial
Deliberately work today under a condition you normally consider wrong for you, the noise, the hour, the device, and complete something real in it without trying to correct the condition.
Why it helps
Needing your conditions to be right means most days are spent fixing conditions rather than working. Widening what you can work in gets those days back.
2 minDifficulty 2
The Trial
Take something impressive you have been carrying past its season, a role, a setup, a presentation, a reputation, and either use it fully today or deliberately shed it.
Why it helps
Carrying something impressive past its season costs you upkeep for no return and you keep hoping it comes back. Using it fully or shedding it both end that.
2 minDifficulty 3
The Trial
Name one ability you have decided you simply do not have, then spend fifteen minutes practising it badly today. Not researching it, doing it. Keep whatever poor first attempt comes out.
Why it helps
Deciding you are not a person who can do something closes it permanently on no evidence. Fifteen bad minutes is enough to find out, and the capacity genuinely builds when you use it.
2 minDifficulty 2
The Trial
Name the hard season you can see coming and the one tool or skill it will require. Begin acquiring that tool today, before the season starts, and do not start anything the season does not need.
Why it helps
Acquiring a tool during the season that needs it means learning while failing, which is the most expensive way to learn anything. Starting now costs you the same effort at none of the pressure.
2 minDifficulty 2
The Trial
Build the specific equipment for a short period today and plan explicitly how you will dismantle it afterwards, naming both before you start.
Why it helps
Equipment built for one season and never dismantled becomes upkeep you pay forever. Naming the dismantling first means you get the season and not the bill.
2 minDifficulty 2
The Trial
Pass one piece of material through your own step today, hand it to whoever can finish it, and come back for the result rather than completing it.
Why it helps
Trying to finish material your own enzymes cannot handle wastes the whole batch. Handing it on and returning for the result gets you all of it.
2 minDifficulty 2
The Trial
Take an early warning you have noticed and dismissed, a tone, a slipping date, a quiet person, and build the defence now rather than waiting for it to become real. Put one concrete protection in place today.
Why it helps
You wait for the problem to actually happen before preparing, which means you prepare under pressure and badly. Building on the early signal costs you one calm afternoon instead of one bad week.
2 minDifficulty 1
The Trial
Take something of yours that is too early to survive scrutiny and move it somewhere protected until it is ready: the private doc, the small trusted group, the draft folder. Move it today and name when it comes out.
Why it helps
Exposing something before it can survive scrutiny usually kills it outright, and you conclude the idea was bad. Protecting it until it is sized to take the pressure is the difference between surviving and not.
2 minDifficulty 1
The Trial
Fill two identical small cups with tap water. Stand one in a larger bowl of lukewarm water that surrounds its sides, leave the other bare, and put both in the freezer. Check after about forty-five minutes, and once the bare cup has an ice skin, take both out.
Why it helps
A simple kitchen experiment that shows why water buffers the cold.
10 minDifficulty 1
The Trial
Sit on a chair beside a taped-out floor square. A helper rolls five soft balls toward the square at irregular moments; launch, stop each before it stops in the square, toss it back and sit down again before the next roll.
Why it helps
A lively five-minute game with bursts of movement and a steady rhythm.
8 minDifficulty 2
The Trial
Mark a square around your work spot with bright orange tape and keep screens and paperwork out of shot. Work on something for ten minutes while a helper, at random moments, tries to slip five small objects into the square; spot each one and put it back outside within five seconds.
Why it helps
A playful test of focus and boundaries while you actually get some work done.
12 minDifficulty 2
