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 2.161–2.220.
The Trial
Before sending your next recurring signal today, build the thing that carries it so it is recognisably yours: the template, the format, the opening line, the sound.
Why it helps
Sending the same signal in whatever form is to hand means nobody can tell it is you. Building the carrier once makes everything after it recognisable.
2 minDifficulty 2
The Trial
Sit with your backs against a wall and set a plate of small snacks three steps out into the open room. Take turns: one person crawls or walks out, takes a single piece and returns, while the other watches the door.
Why it helps
A slow, funny snack with someone else, and a feel for taking turns on watch.
12 minDifficulty 1
The Trial
With a consenting person, work side by side for ten minutes on different small tasks while using completely separate tools and materials.
Why it helps
You turn rock readiness into one concrete experience with a visible finish.
10 minDifficulty 2
The Trial
Arrange today so the resting part of your day is shared with people and the working part is genuinely solitary. Keep both pure, and do not let company leak into the working stretch.
Why it helps
Working alongside people and then resting alone gets you the worst of both: interrupted work and no actual company. Reversing it gives you real focus and real contact in the same day.
2 minDifficulty 1
The Trial
Walk with a partner for 10 minutes. Take turns being the lookout for 60 seconds while the other focuses only on the route ahead, then switch.
Why it helps
Practises shared responsibility and reduces the need for one person to monitor everything at once.
10 minDifficulty 2
The Trial
Decide today whether you are broadcasting or searching on one thing, and do only that role for the whole day rather than alternating.
Why it helps
Alternating between advertising and searching means you do neither properly and the window closes. Choosing one role doubles what you get from the same day.
1 minDifficulty 3
The Trial
Disappear from your phone for twenty minutes today by actually removing the capability, not just the intention: put it in another room, powered off. When the twenty minutes end, pick it back up deliberately.
Why it helps
Trying to ignore a phone that is in your pocket means you spend the whole time resisting it. Removing the capability entirely gives you the twenty minutes back.
2 minDifficulty 1
The Trial
Identify which single step actually sets the rate of one process today, and work only on that rather than on the obvious one.
Why it helps
Optimising the obvious step while another sets your rate means nothing changes and you cannot see why. Finding the real one is where the gain is.
2 minDifficulty 2
The Trial
Put on the first of three tops, jumpers or hoodies that differ clearly in colour and, bare-handed, shell ten peanuts into a bowl, glancing up once between each nut. Change into the second top and use a fresh bowl, then the third. Skip this if you or anyone in the home has a nut allergy, and wipe surfaces afterwards.
Why it helps
A snack ready to eat and a steady, rhythmic handling routine.
15 minDifficulty 2
The Trial
Stand a baking tray or plastic box, tilted slightly, outdoors or inside a larger tray or washing-up bowl that catches the runoff, and shape a channel of sand or gravel with a small pocket dug into one side and roofed with a flat stone, piece of bark or clear plastic lid as an undercut bank. Put a dried lentil in the middle of the open channel and pour a full jug down it to show it washing away, then set a second lentil in the pocket under the bank and pour a full jug again, reshaping the bank and retrying until that lentil stays put. Afterwards tip the sand onto the garden or into the bin, never down a sink.
Why it helps
A calm, hands-in-the-sand build that shows how streambanks give shelter.
18 minDifficulty 2
The Trial
Identify today whose infrastructure your strategy depends on, and check it is still being maintained.
Why it helps
Depending on infrastructure somebody else maintains is fine until they stop, and nobody tells you. One check tells you whether you are exposed.
2 minDifficulty 2
The Trial
Put two equal ice cubes on two saucers in a sunny spot. Collect fist-sized stones from a shaded spot and stack them loosely, at least two layers deep with air gaps, over one saucer, leave the other open, then wait fifteen minutes and uncover the sheltered cube next to the exposed one.
Why it helps
A calm outdoor experiment that shows why shade and air gaps matter on hot days.
18 minDifficulty 1
The Trial
Tape one small square of tissue or paper on top of a broad leaf of a houseplant or garden plant and a matching square on the underside of the same leaf. Mist or sprinkle water over the plant from above ten times, then gently turn the leaf to show both squares.
Why it helps
A gentle look at why so much small life lives on the underside of leaves.
10 minDifficulty 1
The Trial
Rest or wait today among people you already know rather than alone or among strangers, and let the watching be shared rather than keeping your own.
Why it helps
Resting alone means you keep watching and never actually rest, and among strangers you watch harder. With people you know the watching stops being yours.
2 minDifficulty 1
The Trial
Pack a bag for a warm day, pick out the one item that would spoil in heat, such as chocolate, cheese or butter, wrap it in a cloth and then wrap a cold pack around that item alone. Everything else stays as it is.
Why it helps
Your chocolate or cheese arrives intact without hauling a cool box for everything.
5 minDifficulty 1
The Trial
Pick one regular household job that usually means queueing or squeezing past people: the washing machine, the shared kitchen, the shower, the family computer. Find the hour when nobody else needs that space. Do the whole job in that hour, from start to finish, with the time on show at the start and at the end.
Why it helps
Crowded jobs cost you twice, once in waiting and once in friction with whoever else is there. Moving one to the empty hour gives you the same result with no queue, no squeeze and no rush.
2 minDifficulty 1
The Trial
Look at the season you are actually in and move one recurring commitment to a different time of day that suits it better. Make the change today and keep it for the rest of the season.
Why it helps
Keeping the same daily schedule all year means half the year you are working against the conditions and calling it discipline. Moving one commitment with the season costs nothing and recovers those hours.
2 minDifficulty 3
The Trial
Shift the conditions around something you are about to release gradually toward the outside conditions today, rather than releasing it from a protected state.
Why it helps
Releasing something straight from protected conditions means it meets the real ones unprepared and fails. Shifting them gradually costs you days and it survives.
2 minDifficulty 1
The Trial
Before the thing you have been putting off until you feel ready, do two minutes of deliberate warm-up with no output at all: move, pace, say it out loud, write rubbish. Show the warm-up, then going straight into the real task.
Why it helps
Waiting to feel ready means the conditions decide what you get done. Two minutes of deliberately useless warm-up produces the readiness yourself, and it works on cold mornings when nothing else does.
2 minDifficulty 2
The Trial
Generate one condition yourself today that the environment is not supplying, through sustained small repeated effort rather than by finding better conditions.
Why it helps
Waiting for the environment to supply a condition means waiting indefinitely. Generating it yourself is tiring and it is there the same day.
1 minDifficulty 3
The Trial
Build the absorbing structure for one recurring collision today before the next one happens, rather than after it hurts.
Why it helps
Entering repeated collisions without absorbing structure means the damage accumulates on you invisibly. Building it first makes the same collisions survivable.
1 minDifficulty 3
The Trial
Balance a light target on a ledge and try to knock it off with a water jet from a bottle or straw, from below and at an angle. Keep every miss in. When you work out the correction, say it out loud, then land the shot.
Why it helps
Aiming at where things appear to be makes you miss the same way every single time. Learning your own consistent offset is what turns repeated failure into reliable hits.
1 minDifficulty 3
The Trial
Do one short bout of work today beside your exit rather than a long one away from it: ten minutes, within reach of the door, and stop while the exit is still easy.
Why it helps
Long sessions far from an exit mean you are trapped when something changes. A short bout beside the door gets the work done and leaves you free to move.
2 minDifficulty 2
The Trial
Take one thing you have been waiting for a long clear stretch to do. Do it today in several short bouts spread across the whole day instead, and never work on it for longer than a few minutes at a time.
Why it helps
Waiting for a long clear stretch means the thing never starts, because that stretch does not arrive. Several short bouts get it moving today using time you were going to lose anyway.
1 minDifficulty 3
The Trial
Do one demanding thing today in short bouts with rest periods deliberately longer than the bouts themselves. Keep that ratio even when you feel able to continue.
Why it helps
Resting less than you work on something genuinely demanding means you deteriorate through the day and the later hours produce nothing. Longer rests than efforts gets you more total output, not less.
1 minDifficulty 4
The Trial
Spend today moving in short hops between two conditions you need rather than travelling to anything, and make at least four such moves.
Why it helps
Travelling somewhere to get conditions right means losing the day to transit. Short hops between two nearby conditions keeps you in range the whole time.
2 minDifficulty 1
The Trial
Do one task today as several short sorties from one unchanging base, returning to it between each rather than staying out and improvising where to stop.
Why it helps
Staying out and improvising where to stop means you end the day somewhere you did not choose with nothing put away. Short runs from one base leave everything where it belongs.
2 minDifficulty 2
The Trial
Locate one thing fully before moving today, then take it in a single short move, and cover no extra ground looking for alternatives.
Why it helps
Covering ground hoping to come across something spends your energy before you find anything. Locating it first means one short move is all the attempt costs you.
1 minDifficulty 3
The Trial
Run one piece of demanding work today in short bursts with a genuine reset between each, rather than one long continuous effort.
Why it helps
One long continuous push on demanding work means the back half is worthless and you cannot tell. Three bursts with real resets produce more in less time.
2 minDifficulty 1
The Trial
Optimise one thing today for the cluttered conditions you actually work in rather than for open ones, and accept being worse in the open.
Why it helps
Optimising for open conditions you rarely meet means being badly suited to the ones you are in daily. Building for the clutter fixes every day.
2 minDifficulty 1
The Trial
Make one brief striking demonstration today and then immediately return to ordinary work without referring to it again or following up.
Why it helps
Following up on something impressive you did makes it look like you needed it noticed, and it devalues it. Showing it once and going quiet leaves it working on them instead.
1 minDifficulty 4
The Trial
Choose one ordinary shared-space boundary and mark or demonstrate it clearly before explaining it in one sentence. The signal has to be understandable before the explanation.
Why it helps
You get a concrete, memorable result while practising visible boundary as a real human action.
6 minDifficulty 2
The Trial
Before a shared activity, state one clear boundary or limitation that matters and then proceed normally. Keep it specific to the activity.
Why it helps
A visible warning prevents avoidable friction before it begins.
5 minDifficulty 2
The Trial
Pick one claim you make about yourself that is currently only words - reliable, fit, good listener, on top of it. Replace it today with one piece of evidence that cannot be performed: show the record, do the thing in front of the person who doubts it, or hand over the number. One claim, one unfakeable proof.
Why it helps
Claims about yourself that rest on words alone stop being believed, and you cannot tell when that happened. Swapping one for evidence nobody could fake rebuilds trust faster than any amount of explaining.
2 minDifficulty 2
The Trial
Teach one useful thing you know to exactly one person next to you today, in person and hands-on, rather than writing it up for everyone.
Why it helps
Writing something up for everyone reaches nobody properly and you wonder why nothing changed. Teaching one person beside you is what actually spreads it.
2 minDifficulty 2
The Trial
Instead of sending your credentials or past work when someone asks what you can do, show them something from this week: the current state, today's numbers, the thing in progress. Send the live version rather than the archive.
Why it helps
A record tells people what you were like once, which they discount heavily. Showing this week's actual state is harder to argue with and it is the only thing that predicts what you will do next.
2 minDifficulty 1
The Trial
When you next ask someone to join something, lead with the part already running rather than the plan: the thing already built, the people already in, the week already done. Show that before you make the ask.
Why it helps
Asking people to join a plan makes them weigh the risk. Showing them something already running makes it an easy yes, and you only have to get it running once.
2 minDifficulty 1
The Trial
Grow something today in the stage where growth is cheapest, accepting that the later stage will be smaller than the earlier one.
Why it helps
Trying to grow in the expensive stage means growing slowly or not at all. Doing it where it is cheap means you arrive with the mass already built.
2 minDifficulty 1
The Trial
Pick one thing you are short of today - money, time, energy, company - and instead of trying to get more of it, shrink what needs it. Cut the plan down until it fits what you actually have, remove two things entirely, and run the shrunken version. Do not top anything up.
Why it helps
Your instinct when short is to scramble for more, which costs you more than the shortage did. Shrinking what needs the resource gets you through the gap without borrowing or burning out.
2 minDifficulty 1
The Trial
Take one stalled project and reduce it to the smallest version you can actually begin and visibly complete within ten minutes.
Why it helps
You trade scale for survivability and leave with a finished first version instead of a grand stalled plan.
10 minDifficulty 1
The Trial
Name one commitment you are carrying that the next few weeks genuinely cannot fund, and switch it off properly: tell the person, pause the subscription, close the project. Not reduced, off, with the ending communicated.
Why it helps
Carrying everything at reduced quality through a hard stretch costs you more than dropping one thing cleanly. Shutting one down properly frees enough to do the rest without failing at all of it.
2 minDifficulty 1
The Trial
Declare a genuinely low mode for a defined period starting today, say what you will not be doing in it, and tell whoever needs to know. Not reduced effort, a different mode.
Why it helps
Running at full tilt all year means the low periods happen anyway, unplanned and at the worst time. Declaring one properly costs a conversation and you come out of it intact.
2 minDifficulty 1
The Trial
Scatter at least ten soft items across a room floor, then clear a single lane at least a body-width wide through them, with every item at least 20 cm off the lane edges and no furniture corners beside it, and put a cushion or tape mark at each end half a metre short of the wall. Barefoot or in trainers, never socks on a hard floor, on go move quickly along the lane and back three times, touching the end mark each time, within twenty seconds.
Why it helps
A short heart-rate burst with a built-in lesson in planning ahead.
5 minDifficulty 3
The Trial
Take the next hour and deliberately change your position four times as your state changes: stand when you flag, move to light, step outside, sit when you settle. Adjust on what you notice rather than on a timer.
Why it helps
Setting up once and staying put means you spend most of the hour in conditions that stopped suiting you. Four small moves, each triggered by what you notice, keeps you working well the whole time.
1 minDifficulty 4
The Trial
Stand with one hand on a thick tree trunk or pillar in a garden or park while a partner walks two slow laps around it. Sidle around the trunk to stay on the far side from them the whole time.
Why it helps
A silly, surprisingly tactical game that gets two people moving and laughing.
5 minDifficulty 2
The Trial
Gather one pile of things that have come in: post, papers, receipts, flyers, or the notes on your desk. Make two places, one for small things you can deal with in under a minute and one for too-big things. Go through the pile once, item by item, into the two places. Then deal with every small one.
Why it helps
A pile you take in all at once stays a pile. Sorting it by size clears the small things straight away and leaves you a short, honest list of the few that need real time.
2 minDifficulty 2
The Trial
In one situation today where you cannot see far ahead, put all your effort into the approach rather than the plan: get closer, then act in one move.
Why it helps
Planning far ahead in a situation you cannot see into produces a plan that is wrong. Spending that effort getting closer means your one move actually lands.
1 minDifficulty 4
The Trial
Take something you want a specific group to see and put it somewhere only they look, rather than broadcasting it: the team channel, the direct message, the shared doc, the one-to-one.
Why it helps
Broadcasting to everyone means the people you wanted reach it diluted and the people you did not also see it. Putting it where only they look gets a real response and no side effects.
2 minDifficulty 2
The Trial
Work out which single thing about your work is actually visible to the person you need to reach. Put all of today's signalling effort into that one thing and stop decorating anything they will never see.
Why it helps
Spreading your effort across parts nobody can see means the one part that reaches people is the roughest thing you own. Putting everything into it changes what they actually receive.
1 minDifficulty 3
The Trial
Do one thing today slowly enough to make no noise at all, pausing between each movement, and accept the pace rather than trying to recover it.
Why it helps
Trying to be quick and quiet at once means you are neither, and the noise is what gets noticed. Accepting the slow pace is what actually buys you the silence.
2 minDifficulty 2
The Trial
Attempt nothing new today through a stretch you know is poor, and make continuing to exist intact the only objective.
Why it helps
Attempting things through a genuinely poor stretch spends the reserve you need to reach the good one. Just continuing intact is what gets you there.
2 minDifficulty 1
The Trial
Take something you have been saying that is not landing and put it somewhere with built-in amplification rather than saying it louder: the established newsletter, the meeting that already has attention, someone else's platform. Place it today.
Why it helps
Saying the same thing louder and more often just makes people tune you out. Putting it somewhere that already carries gets it heard once without you repeating yourself at all.
2 minDifficulty 2
The Trial
Instead of posting something alone, time it to go out alongside other people's on the same thing: the shared launch, the group thread, the collective post. Coordinate the timing with at least two others today.
Why it helps
Being the only voice saying something makes you the one who takes the response, good or bad. Going out alongside two others spreads that and the whole thing carries further.
1 minDifficulty 4
The Trial
Turn one normal sentence you genuinely need to tell someone into a short improvised melody and sing it across the room. Do not explain first.
Why it helps
Practises expressive confidence and makes an ordinary social exchange memorable instead of automatic.
10 minDifficulty 2
The Trial
Make up a distinctive three- to five-note phrase that is yours alone. Walk the edge of a room or garden and sing it once from each of its four corners, then go round the loop a second time at the same pace.
Why it helps
A playful way to claim a space and find your own voice.
5 minDifficulty 2
The Trial
Multiply the surface through which one faint signal can reach you today rather than improving how you process it.
Why it helps
Improving how you process a faint signal cannot help if it never reaches you. Multiplying the surface is what makes single units detectable.
1 minDifficulty 4
The Trial
Escape one situation today by the route your supposed weakness suits, rather than the route everyone expects you to take.
Why it helps
Taking the expected escape route means competing on the trait you are worst at. The route your weakness suits is usually wide open.
2 minDifficulty 2
The Trial
Fill a tall clear jug at least 25 cm deep with strong, cooled tea and tie a white button to a length of thread. Looking straight down, lower the button a centimetre at a time until you can no longer see it, mark the thread at the surface with a pen and measure the depth with a ruler; if the button is still visible at the bottom, lift it out, stir in more strong tea and start again.
Why it helps
A slow, surprising look at how quickly light fades in water.
10 minDifficulty 1
The Trial
Fill a glass with water, set it on the table and sit upright beside it. Drink the whole glass slowly through one thin coffee stirrer, leaving the glass on the table the entire time.
Why it helps
A slow, calming drink that also gets a full glass of water into you.
15 minDifficulty 1
The Trial
Pick one position today from which the whole of a situation is visible, wait there, and refuse to go walking around it instead.
Why it helps
Walking around a situation means seeing one bit at a time and never the whole. One position that shows all of it tells you more in ten minutes than an hour of moving.
2 minDifficulty 2
