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 481–540.

Cheapest Bluff Goes First

HIGH
Western Hognose Snake · Death-Feigning Theater

The Trial

Next time something threatens you today, run the escalation in order and nothing out of order: first the cheap bluff, hold it for ten seconds, and only if that fails go to the expensive one. Never start at the top.

Why it helps

Starting at your most extreme response means you have nothing left when the bluff would have worked. Running the cheap one first usually ends it and costs you nothing.

1 minDifficulty 4

Check Who Is Driving

LOW
Amber Snail · Damp Persistence

The Trial

Take one urge you have had repeatedly today, to check, buy, scroll or reply, and trace who benefits from you having it. Name the beneficiary out loud, then deliberately do not act on that urge once.

Why it helps

Most of your repeated urges were designed by someone with an interest in you having them. Naming who benefits, once, makes the next one much easier to notice and not act on.

2 minDifficulty 1

Chirp While Your Nose Is Buried

MID
Common Cusimanse · Group Foraging

The Trial

While a group works head-down today, keep a continuous low stream of contact going rather than reporting at intervals.

Why it helps

Reporting at intervals while everyone is head-down means the group drifts apart between reports. A continuous low stream costs you nothing and holds it together.

2 minDifficulty 2

Choose the Open Slope Over the Cover

MID
Argali · Highhorn

The Trial

Name one thing you have been keeping hidden to stay safe. Make it visible today in one deliberate way, and use the earlier warning that visibility gives you.

Why it helps

Keeping something hidden to stay safe also means nobody tells you about a problem with it until it has arrived. Visibility costs you cover and buys you time, which is usually the better trade.

2 minDifficulty 2

Choose your single strongest reason

LOW
Angulate Tortoise · One Spur

The Trial

Pick one thing you want to ask someone for this week. Run through every reason in your head, then choose the single strongest one. Say the request and that one reason out loud in one sentence of twenty words or fewer, counting the words on your fingers. Drop every other reason.

Why it helps

You walk into important conversations with ten weak reasons and get talked round. Arriving with one strong, prepared point makes you clearer, quicker and much harder to brush aside.

2 minDifficulty 2

Circle and Flash a Scarf Side-On Three Times

HIGH
Lady Amherst's Pheasant · Ribboned Reserve

The Trial

Place a consenting friend or a large cuddly toy in the middle of a clear space and hold a patterned scarf. On go, trot a half-circle around them, stop, and in one movement sweep the scarf across your face while turning your whole side to them, then repeat twice more, all within thirty seconds.

Why it helps

A silly, fast bit of performance that gets your heart rate and your confidence up.

3 minDifficulty 3

Circle One Target Without Contact

HIGH
Wall Spider · Star Web

The Trial

Place a harmless object on the floor and circle it quickly three times while laying a string boundary around it, never touching the target.

Why it helps

A boundary laid at speed without touching the thing it surrounds, which is harder than it looks.

5 minDifficulty 4

Circle Twelve Objects Into One Tight Group

MID
Dusky Dolphin · Acrobatic Joy

The Trial

Spread twelve small safe objects across a table, then use both hands moving around the outside to push them into one tight central group without picking any up.

Why it helps

You turn acrobatic joy into one concrete experience with a visible finish.

10 minDifficulty 2

Circulate One Reply Card Around Three Screened Seats

MID
Superb Fairywren · Blue Social Thread

The Trial

Seat three or more willing people around a table with propped boards or open books between them so no one can see anyone else, each with a pen of their own colour. Pass one card round the screens in the same order for three full rounds, with each person adding one short line or doodle that answers the entry before theirs.

Why it helps

A small, warm group conversation that leaves a keepsake behind.

12 minDifficulty 2

Circulation, Not Suffocation

HIGH
African Rock Python · Heavy Stillness

The Trial

Interrupt the flow a situation depends on rather than its visible activity today, and identify that flow before acting.

Why it helps

Targeting the visible activity means a long struggle you may not win. Interrupting the flow it depends on resolves it before anyone notices.

1 minDifficulty 3

Claim one quiet spot to regroup

LOW
Dusky Sleeper · Tidal Shelter

The Trial

Choose one fixed, quiet place you can always reach: a chair, a step, a corner. Take a change that has upset your plans this week. Go straight to that place, sit still for two minutes with a timer running, then say out loud the one next step you will take.

Why it helps

Sudden changes push you into quick reactions you later regret. Having one fixed place to stop for two minutes gives your head time to settle, so the next step you take is chosen rather than grabbed.

2 minDifficulty 1

Claim One Ready-Made Nook

LOW
Welcome Swallow · Borrowed Eaves

The Trial

Find an existing sheltered nook or support you normally overlook and use it for one useful five-minute task. Photograph the setup.

Why it helps

Practises opportunistic use of infrastructure by turning an already-built feature into a useful working site.

6 minDifficulty 1

Clamber, Do Not Fly

MID
Crested Coua · Island Composure

The Trial

Pick one search you have been doing by covering ground. Do it today by moving slowly through a small area and looking closely, and cover no new ground at all.

Why it helps

Searching by covering ground means you move past everything too fast to see it, and conclude there is nothing there. Slow close looking in a small area is where the things you missed actually are.

2 minDifficulty 2

Clamp Five Slid Beanbags With Resting Tongs

HIGH
Spotted Wobbegong · Carpet Ambush

The Trial

Rest open salad tongs flat on a smooth table with their tips at the edge of a marked lane. A consenting helper ties a ribbon tail to a small beanbag and, at moments picked by a die roll off camera, slides it along the lane past the tips, five times; each time you snap the tongs shut on the beanbag, and the helper then tugs the ribbon steadily for three seconds.

Why it helps

A tense reflex game with a satisfying clack each time.

4 minDifficulty 3

Clap, Listen, Then Check

LOW
Oilbird · Cave Echolocation

The Trial

Stand in a dark or unfamiliar room with your eyes closed. Clap once, sharply, and listen to how the return changes. Move three steps, clap again, and keep going until you can say where the nearest wall and the open side of the room are. Then open your eyes and check.

Why it helps

You navigate unfamiliar situations by looking, so when there is nothing to see you stop moving. Learning to send a signal and read the reply gives you a way forward in the dark.

2 minDifficulty 1

Clatter, Do Not Fight

MID
Keel-billed Toucan · Color Utility

The Trial

Have one competitive thing out in the open today in a harmless form, a game, a bet, a timed contest, with the person you have been quietly competing with.

Why it helps

Quiet competition you never name keeps getting worse because neither of you can resolve it. One harmless contest usually clears it in an afternoon.

2 minDifficulty 2

Clean One Surface Without Sealing It

MID
Australian Green Tree Frog · Rain Timing

The Trial

Clean one vented, perforated or breathable household surface without covering its openings. The finished surface must stay able to pass air or water.

Why it helps

You get a concrete, memorable result while practising rain timing as a real human action.

8 minDifficulty 2

Clean One Tiny Shelter

LOW
Giant Redeye · Night Focus Pattern

The Trial

Choose one small enclosed container or drawer, remove debris, dry it, and return only what belongs there. Photograph the cleaned space.

Why it helps

One small space is genuinely clean rather than rearranged, and it stays that way longer.

8 minDifficulty 1

Clean One Ugly Thing Silently

LOW
Cinereous Vulture · Quiet Stewardship

The Trial

Find one neglected dirty or messy thing that everyone ignores and restore it without announcing what you are doing. Stop when the visible improvement is complete.

Why it helps

Leaves the environment genuinely better while building quiet responsibility without needing recognition.

10 minDifficulty 1

Clean Up One Mess Nobody Claims

MID
Greater Adjutant · Messy Service

The Trial

Choose one small safe mess in a space you legitimately share—crumbs, packaging, clutter, stale cups, or an untidy common surface—and clean it without announcing that you did it. Use normal hygiene precautions.

Why it helps

You improve a shared environment and practise useful service that does not depend on recognition.

10 minDifficulty 2

Clear Five Lentils Only After an Answering Nod

MID
Scarlet Cleaner Shrimp · Red-Stripe Service

The Trial

A consenting partner holds five dried lentils or paper bits in loosely cupped hands, with a shuffled face-down stack of seven playing cards, five red and two black, beside them. Before each reach, give your agreed signal, such as two raised fingers waved side to side; your partner turns the next card out of your sight and nods for red or shakes their head for black. On a nod, pick out one lentil; on a shake, lower your hand, wait three seconds and signal again, until all seven cards are used.

Why it helps

A playful drill in asking and actually listening to the answer before you reach, which carries over to any close-contact task.

5 minDifficulty 2

Clear It for Whoever Comes Next

LOW
African Forest Elephant · Forest Pathmaking

The Trial

Find one route other people use that has something in the way - an overgrown path, a blocked doorway, a cluttered corridor, a stuck gate. Clear it properly today, not just enough for you to pass, and leave it so the next person does not have to think about it. Tell nobody you did it.

Why it helps

Paths you squeeze past every day cost everyone a little, forever, and nobody fixes them because nobody owns them. Clearing one properly is the cheapest useful thing you will do this week.

2 minDifficulty 1

Clear Muddy Water Through a Cloth Gill

LOW
Freshwater Pearl Mussel · Pearlbed Patience

The Trial

Stand a clear glass in a large bowl, rest a funnel or small sieve lined with a tightly woven cloth folded double in its mouth, and pile gravel and sand into the bowl around the glass and up the funnel's sides so only its open mouth sits above the bed. Stir a spoonful of soil into a jar of water and pour it slowly straight onto the exposed cloth, then lift out the funnel and stand the muddy leftover beside the filtered glass with the cloth opened out.

Why it helps

A simple demonstration of why clean gravel matters to a river, made with kitchen things.

15 minDifficulty 1

Clear One Cushion-Blocked Doorway in a Chain

MID
Damaraland Mole-rat · Tunnel Colony Labor

The Trial

Pile cushions and pillows into a doorway until it is blocked. Line up behind it: the front person pulls a cushion free and passes it back, each person hands it on, and the last person stacks it neatly. Keep going until the doorway is clear.

Why it helps

A quick group job that shows how a line beats everyone grabbing at once.

10 minDifficulty 2

Clear One Floor Runway Between Two Rooms

MID
Meadow Vole · Grass-Run Community

The Trial

Choose two spots you travel between every day, such as the bed and the desk.

Why it helps

A faster, safer route through your home, cleared in one go.

15 minDifficulty 2

Clear One Patch and Maintain It

MID
Powder Blue Tang · Territorial Harmony

The Trial

Choose one cluttered patch of desk, shelf or floor, clear it completely, then return only the objects that genuinely belong there. Everything else has to move outside the patch.

Why it helps

You create one dependable usable space instead of repeatedly fighting the whole room.

10 minDifficulty 2

Clear One Pile-Up Point at Speed

HIGH
Mahi-mahi · Neon Pursuit

The Trial

Identify the one spot where things pile up around you — a doormat, a drain, a hall table, a sink edge — and clear it completely in three minutes at full speed. Deal with each item as it comes rather than sorting first.

Why it helps

The spot that quietly accumulates everything is empty, in less time than you spend stepping round it.

3 minDifficulty 2

Clear One Surface in Fewest Movements

LOW
Brown-throated Sloth · Slow Camouflage

The Trial

Pick one cluttered surface, then clear it completely while counting every separate movement you make. Say the total out loud once the surface is empty.

Why it helps

One surface ends up clear, and you find out how many movements you normally spend without noticing.

10 minDifficulty 2

Clear One Unbroken Path From Seat to Door

MID
Green Basilisk · Waterline Sprint

The Trial

Pick the seat where you will spend the next session, choosing one whose route to the nearest door has at least three items in the way. Move every bag, cable, box and shoe out of a clear lane at least shoulder width from the seat to the door, putting each item away rather than into another walkway or doorway, then sit down and start your task.

Why it helps

A tidier room and a genuinely safer workspace.

10 minDifficulty 2

Clear Ten Stray Items Returning to One Chair

MID
Ruddy Darter · Perch Return

The Trial

Sit in one chair with a view of a cluttered room. Spot one out-of-place item, get up, put it away, and sit back down in the same chair before spotting the next; repeat until ten items are cleared.

Why it helps

A cleared room, done in bites small enough that it never feels like a chore.

15 minDifficulty 2

Clear the Court Before Anyone Arrives

MID
Wahnes's Parotia · Stage Discipline

The Trial

Clear the background of one thing today before doing it, removing the clutter rather than working around it, and keep it clear while you work.

Why it helps

Working against clutter means your effort competes with the mess behind it and reads as noise. Clearing the background first makes the same work land.

2 minDifficulty 2

Clear the Perch Then Flare Scarf Plumes

HIGH
Lesser Bird-of-paradise · Refined Display

The Trial

Tape a one-metre perch line on the floor and set three small objects on it, holding a gold or yellow scarf in each hand. When a random-interval timer app signals that a female has arrived, clear all three objects off the line, step onto it, bow low, shake both scarves, then fling them up over your back and hold the flared freeze for five seconds, all within thirty seconds.

Why it helps

A quick, joyful burst of performing that builds confidence.

4 minDifficulty 3

Clear the Surface First

MID
Oscar Fish · Soft Dig Claim

The Trial

Before starting the thing you keep failing to start, clear the physical surface it needs first and nothing else: the desk, the bench, the table. Carry everything off it, leave it bare, and only then begin.

Why it helps

You start on a cluttered surface and lose twenty minutes to friction every time. Clearing it completely first is five minutes and the work actually begins instead of stalling.

2 minDifficulty 2

Clear Three Towel Ridges in Sideways Bounds

HIGH
Verreaux's Sifaka · Sidelong Hop

The Trial

On grass, with shoes on, set two markers four metres apart and lay three rolled towels across the strip between them as low ridges. Standing sideways at the first marker, bound two-footed sideways over all three towels to touch the second marker in six hops or fewer, then return the same way, finishing within twelve seconds.

Why it helps

Twelve seconds of explosive lateral work that also happens to look hilarious.

3 minDifficulty 4

Click to Detect a Hidden Board Blindfolded

MID
Commerson's Dolphin · Patchwork Dolphin Play

The Trial

Before you put the blindfold on, a helper tosses a coin ten times out of your sight and writes the order of present (P) and absent (A) on a card. Sit blindfolded; on each of ten turns the helper follows the card, silently holding a large board or tray thirty centimetres in front of your face or keeping it away, while you make sharp tongue clicks and say present or absent.

Why it helps

A surprising discovery that you can hear what you cannot see.

10 minDifficulty 3

Clicks Above Where Killers Hear

MID
Vaquita · Fragility

The Trial

Move one piece of your communication today into a channel the party you want to avoid cannot receive, and verify they cannot.

Why it helps

Communicating in a channel the wrong party monitors means everything you say reaches them. One channel they cannot receive solves it permanently.

2 minDifficulty 2

Climb on Air You Did Not Make

MID
Wandering Glider · Long Journeys

The Trial

Take a goal too big for your own effort and attach it to something already moving at scale: an existing event, a seasonal push, someone else's launch, a current trend. Attach it today rather than building your own momentum.

Why it helps

Generating your own momentum for something big is where most attempts die. Attaching to a system already moving means the distance gets covered whether or not you have energy that week.

2 minDifficulty 2

Climb on Someone Else's Warm Air

LOW
Turkey Vulture · Efficiency

The Trial

Find something already in motion today that is heading where you want to go, an existing project, meeting, trip or momentum, and attach your task to it rather than starting your own.

Why it helps

Starting your own effort for something already underway elsewhere doubles your work for the same result. Attaching to what is already moving gets it done for almost nothing.

2 minDifficulty 1

Climb on the Sun-Heated Slope

MID
Demoiselle Crane · Light Strength

The Trial

Borrow the lift for one thing today from something already rising nearby rather than generating it yourself, and name the source.

Why it helps

Generating your own lift at a small size means not getting high enough and exhausting yourself. Borrowing it from something already rising gets you over.

2 minDifficulty 2

Climb the Dam for Salt

LOW
Alpine Ibex · Cliff Balance

The Trial

Name the one thing your safe arrangement does not provide, and make a deliberate specific effort to get it today.

Why it helps

Safe arrangements always lack something, and you adapt to the lack instead of noticing it. Naming it means one deliberate trip fixes a chronic deficit.

2 minDifficulty 1

Climb Two Kilometres to Sleep

LOW
Common Swift · Winglife

The Trial

Take one thing you normally rest from by stopping altogether. Rest from it today by going to a higher, broader version of the same thing instead, reading about it or planning it rather than doing it.

Why it helps

Resting by stopping completely means you lose your thread and spend the next session finding it again. Going higher in the same thing rests the tired part of you and keeps the thread intact.

2 minDifficulty 1

Climb, Then Pick the Right Wind

MID
Marmalade Hoverfly · Harmless Warning

The Trial

Before putting effort into travelling toward something today, look for an existing current heading there and get into it instead.

Why it helps

Travelling toward something under your own effort means arriving late and tired. Finding the current going there first costs you an hour of looking.

2 minDifficulty 2

Clock Five Even Laps Down One Hallway

MID
Cliff Swallow · Mud-Cup Return

The Trial

Stick a paper mark on a wall at one end of a hallway or long room as your nest spot and put a far marker at least five metres away, with the camera at the nest end so the whole route is in frame. Walk to the far marker, touch it and return to touch the nest mark five times at a steady pace while a timer runs in view.

Why it helps

A light, steady movement break with a pleasing pacing challenge.

8 minDifficulty 2

Close One Fragile Item Inside a Shell

LOW
Asian Leaf Turtle · Litter-Brown Shell

The Trial

Wrap one fragile object so its most vulnerable end can be closed behind a movable flap while the rest stays rigid.

Why it helps

You build a simple defensive closure around the part that needs protection most.

8 minDifficulty 1

Close One Gap in Three Seconds

HIGH
Cougar · Range Stealth

The Trial

Set two safe floor marks a few steps apart. From stillness, cross from one to the other in under three seconds and stop under control.

Why it helps

You turn range stealth into one concrete, visible experience instead of an abstract idea.

5 minDifficulty 3

Close One Vulnerable Kit

LOW
Malayan Box Turtle · Protective Retreat

The Trial

Pack one small everyday kit so every essential item is enclosed and nothing can fall out when gently turned over. Photograph it closed.

Why it helps

The kit survives being carried upside down, which is the only real test of packing.

6 minDifficulty 1

Close the Clasp Knife and Keep It

HIGH
Texas Unicorn Mantis · Thorned Disguise

The Trial

Pick one thing you have taken hold of and keep half-releasing, a commitment or a decision. Close on it fully today, and refuse the next opportunity to loosen your grip on it.

Why it helps

Half-holding a decision means you carry its cost and get none of its benefit, and it stays open for months. Closing fully once ends the negotiation with yourself.

1 minDifficulty 3

Close the Distance Before You Ask

LOW
Bobcat · Ambush

The Trial

Pick one ask you have been making from too far away, and spend fifteen minutes closing the distance before you make it: get into the room, the thread, the proximity. Only ask once you are close, and if you are not close enough, do not ask.

Why it helps

Asking from too far away burns the ask and teaches the other person to say no to you. Closing the distance first turns the same request into an easy yes.

2 minDifficulty 1

Close the Instant It Registers

MID
Black-headed Ibis · Careful Probing

The Trial

Today, act on the next small thing you notice within ten seconds of noticing it, with no deliberation: the reply, the fix, the thing out of place. Do it the moment it registers.

Why it helps

The gap between noticing something small and doing it is where it turns into a list item you carry for a week. Closing it immediately costs ten seconds and removes it entirely.

2 minDifficulty 2

Close the Other Doors

MID
American Badger · Burrow Strategy

The Trial

Show each escape you actually use to dodge one task: the phone, the other tab, the snack, the other room. Physically close each one, naming it as you go. Then start the task and do two unbroken minutes of real work.

Why it helps

Tasks feel hard when they are really just escapable. Removing the exits does more for your focus than willpower ever will, because there is nowhere else left to go.

2 minDifficulty 2

Close the Ring and Do Not Move

LOW
Musk Ox · Herd Armor

The Trial

Check today whether a standard response of yours still fits the threat you actually face, and change it if the threat has changed.

Why it helps

A response that worked against an old threat keeps feeling right and can be the thing that destroys you. One comparison tells you whether it still fits.

2 minDifficulty 1

Close the Spined Basket

MID
Green Lynx Spider · Alert Leap

The Trial

Take one thing you have been securing from one direction. Close on it from every direction at once today, every requirement and every party at the same time, rather than sequentially.

Why it helps

Securing something one direction at a time gives whoever is on the other side time to reorganise between your moves. Closing everything at once leaves nowhere for it to go.

2 minDifficulty 3

Close to Thirty Metres First

HIGH
Bengal Tiger · Silent Ascent

The Trial

Spend almost all your effort today on closing the distance to one thing, and keep the final move short.

Why it helps

Spending your effort on the move itself means launching from too far and missing. Putting it into the approach means a short move is enough.

1 minDifficulty 3

Closing, Not Just Withdrawing

LOW
Indochinese Box Turtle · Wise Retreat

The Trial

Convert one withdrawal today into a complete closure, so there is no remaining opening rather than a smaller one.

Why it helps

Withdrawing leaves an opening that anyone persistent can work on you through, and they will. Closing completely means there is nothing left to try.

2 minDifficulty 1

Cluster Into the Texture

LOW
Spotted Lanternfly · Wax-Wing Signal

The Trial

Place one thing today among others that look the same rather than giving it its own space, and remove whatever was setting it apart.

Why it helps

Giving something its own space is exactly what makes it the thing people look at. Putting it among identical things means nobody picks your one out at all.

2 minDifficulty 1

Coagulate on Contact

LOW
Indo-Pacific Horseshoe Crab · Ancient Resilience Strategy

The Trial

Set up one response today that seals a problem off within minutes rather than relying on compartments to contain it.

Why it helps

Relying on compartments you do not actually have means a problem reaches everything before you notice. One minutes-fast sealing response covers all of it.

2 minDifficulty 1

Coarse Food, All Day Eating

LOW
Rhinoceros · Grounded Force

The Trial

Work out today what a cheap option you are using actually costs you in time, state the number, and decide whether to keep it on that basis.

Why it helps

Cheap options feel free because the cost comes out of your hours, not your money. Putting a number on it usually changes what you choose.

2 minDifficulty 1

Coat One Paper Tube in Household Fluff

LOW
Household Casebearer Moth · Dust-Grain Sleeve

The Trial

Roll a strip of paper into a flat sleeve about a finger long and wrap it in double-sided tape. Gather fluff from a dryer filter, hairbrush, rug or sofa seam and press it on until no paper shows, keeping both ends clear so a pencil slides straight through.

Why it helps

A quirky, calm make that turns household fluff into something oddly beautiful.

15 minDifficulty 1

Coated in Drying Mud

LOW
Javan Rhinoceros · Soft Giant

The Trial

Apply one cheap external layer today that solves two problems your own structure cannot, and name both.

Why it helps

Trying to solve two problems by changing your own structure takes months. One cheap applied layer handles both of them this afternoon.

2 minDifficulty 1

Cocked Against a Spring, Held by a Latch

HIGH
Spottail Mantis Shrimp · Burrow Strike

The Trial

Store energy or preparation slowly behind one holding mechanism today, and release it in a single instant rather than spending as you go.

Why it helps

Spending effort as you generate it means your output never exceeds your rate. Storing it behind a latch lets one release exceed anything you could do live.

1 minDifficulty 3
