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 541–600.
1Rendam satu tangan di air dingin selama enam puluh detik
2Rangkai lima manik dengan tiap tangan, dengan waktu
3Bandingkan kedua waktunya dengan suara keras
The Trial
Fill one bowl with cold tap water and leave a second bowl empty. Put one hand in the cold water for sixty seconds while the other stays dry and warm in a pocket. Then, with a visible timer, thread five beads or button five buttons with each hand and compare the times out loud.
Why it helps
You lose most of your capability by letting heat leak out - sleep, food, warmth, recovery - and then blame your discipline. Feeling the difference in your own hands makes that trade impossible to ignore.
1Letakkan lima camilan rendah di ruangan berperabot
2Ambil semuanya, kepala tetap di bawah perabot
3Bersiul dua nada tiap kali; rekan Anda menjawab
The Trial
Set five small snacks in view on the floor or low surfaces around a room with sofas, tables or beds. Move around the room collecting them while staying lower than the furniture tops, and after each pickup give a two-note whistle that your partner in the room answers.
Why it helps
A playful game that keeps two people in touch without needing to see each other.
During one shared activity, notice and collect one useful leftover, forgotten resource or overlooked opportunity that would otherwise be wasted. Put it to immediate use.
Why it helps
Trains resourcefulness and leaves the user with value recovered from something others ignored.
2Pindahkan satu kacang hanya saat keduanya terangkat
3Membeku begitu salah satunya turun
The Trial
A helper holds a green card for food and a thumbs-up for safety, raising and lowering each at random. Move one nut from the bowl to your cup only while both are showing at the same time, and freeze the moment either drops.
Why it helps
A fast, funny timing game that rewards patience over grabbing.
Scatter twenty pegs along a strip about a metre wide down a lawn or long room. Stand in a short file, one behind another, with two or three willing people facing along the strip; only the rearmost person moves, walking round to take the front place and picking up only the pegs within reach there, while everyone else stays still, until all twenty are collected.
Why it helps
A quick group game that makes a boring tidy-up fun.
Instead of creating something from scratch today, collect five specific things from five different sources and combine them into one piece of yours. Credit where each came from.
Why it helps
Waiting to invent something original is why you have produced nothing. Five collected pieces combined is genuinely yours, takes an afternoon, and nobody else has that combination.
Pick one green leaf from a houseplant or garden, still attached or freshly fallen. Cut a small spider shape from paper and colour it with pencils, pens or paint, testing it against the leaf and adjusting until the shades match, then lay it on the leaf.
Why it helps
A calm little art task that trains your eye for colour.
Replace one signal of yours that reflects past performance today with something that shows your current state instead.
Why it helps
A signal based on your history keeps earning you credit you no longer deserve, and people discover that at the worst moment. Current state never has that problem.
2Warnai satu seperti permadani, letakkan keduanya terbuka
3Penolong melihat selama 10 detik dan menunjuk
The Trial
Cut two identical fish shapes about the size of your hand from plain paper, colour one with the tones and pattern of one patch of patterned floor, rug or doormat and leave the other plain, then lay both flat on that patch while a consenting helper is out of the room. The helper then looks down from standing height for ten seconds and points at every fish they can see; if they point at yours, recolour it and try again with them out of the room.
Why it helps
A quiet colouring puzzle that trains your eye for tone and pattern.
1Periksa halaman, lalu pembantu menyembunyikan sepuluh tutup botol
2Pakai sarung tangan, jalan pelan berbaris, usap rumput
3Terus usap sampai kesepuluhnya ditemukan
The Trial
Check a patch of your own lawn for sharp objects and animal mess first. While you and at least one partner wait indoors, a helper who will not search pushes ten bottle caps down into the grass; then put on garden gloves, form a line abreast and walk slowly across, sweeping your hands through the grass, until all ten caps have been found.
Why it helps
A cooperative search that turns a patch of ground into shared teamwork.
1Pasang satu filter, lalu ambil satu rentang waktu feed
2Biarkan semua yang tidak cocok berlalu
3Simpan hanya yang cocok
The Trial
Take a large undifferentiated flow you normally skim, the feed, the inbox, the channel, and pass a fixed period of it through one filter today, keeping only what matches. Set the filter first.
Why it helps
Judging each item as it arrives is what makes a feed exhausting and leaves you with nothing. One filter set in advance lets the whole flow pass and you keep only what you meant to.
Sit at a table over a tray, rest your elbow on a tape mark so it stays fixed there and hold that hand up, fingers spread, with a cup within reach of it. A consenting helper flips a coin off camera to call "tide in" or "tide out" every ten seconds or so; at tide in they sprinkle a pinch of hole-punch paper dots from about thirty centimetres above your hand and you comb through the falling shower in slow, steady sweeps, closing your fingers into your palm to trap dots and dropping them in the cup, and at tide out you close your hand into a still fist; carry on for at least three tide-in periods until twenty dots are in the cup.
Why it helps
A playful, rhythmic catching game in letting the flow bring the work to you.
Take something several of you individually want to raise. Coordinate today so you all raise it at the same moment rather than in sequence, and make sure nobody goes first alone.
Why it helps
Raising something alone when others want the same thing means you absorb the whole reaction and they wait to see how it goes. Everyone arriving at once means nobody is the one exposed.
Gather ten objects of one colour today and arrange them deliberately in one place, then come back twice during the day and rearrange them until the arrangement is better than when you left it.
Why it helps
Doing something impressive once tells people nothing, because anyone can manage one burst. Returning to it repeatedly is what shows the judgement you actually have.
1Sebutkan tempat atau rutinitas yang dulu menenangkan Anda
2Jangan pilih versi yang lebih baik
3Kembalilah tepat ke yang itu
The Trial
Identify one reliable place or routine that has steadied you before and that you have drifted from. Go back to exactly that one today rather than finding a better version of it.
Why it helps
Looking for a better version of what already steadied you means you spend the hard weeks searching instead of recovering. Going back to the known one works immediately because you already know it does.
1Tulis dua atau tiga hal yang dibutuhkan minggu Anda
2Pilih salah satunya
3Lakukan satu hal hari ini untuk mengamankannya
The Trial
Write down the two or three specific things your week genuinely depends on, not the ones that merely fill it: the one supplier, the one person, the one tool. Then do one thing today to protect or secure one of them.
Why it helps
Being busy everywhere hides the two or three things everything actually rests on, so you never protect them. Naming them takes ten minutes and tells you exactly where a bad week would come from.
Pick one thing you normally do at a fixed time today. Write down the actual condition that should trigger it instead, then wait for that condition and do it when it arrives rather than when the clock says.
Why it helps
Running your day on the clock means you act when the conditions are wrong and blame yourself for the poor result. Naming the real trigger puts the effort where it actually works.
3Jika tidak, tetap di dalam dan jangan berkegiatan berat
The Trial
Before doing anything demanding today, check honestly whether conditions are mild for it. If they are, go out and do it fully; if not, stay in and do nothing demanding at all.
Why it helps
Pushing a demanding thing through unfavourable conditions produces a poor version you then have to redo and tells you nothing about your ability. Checking first spends the effort where it lands.
Take one stretch of work today and set a fixed interval at which you stop and genuinely come up for air. Keep the interval even when the work is going well, and do not shorten it.
Why it helps
Skipping breaks when the work is flowing is exactly when you need them, and the collapse comes hours later disguised as something else. A fixed interval you keep regardless is what makes a long stretch survivable.
2Tempel selotip memanjang pada dua gelas yang sama
3Tuang keduanya pada saat yang sama
4Tandai selotip di titik busa tertinggi
The Trial
Chill one small bottle of sparkling water in the fridge and leave a second at room temperature or stand it in warm tap water. Stick a strip of tape up the side of each of two identical glasses, pour both at once side by side, and mark each tape with a pen at the highest point its foam reaches.
Why it helps
A one-minute kitchen experiment that shows why cold drinks stay fizzy.
1Ambil satu hal yang diberitahukan kepada Anda hari ini
2Bandingkan dengan yang sudah Anda ketahui
3Bertindaklah hanya berdasarkan perbedaannya
The Trial
Before acting on something you were told today, deliberately compare it against what you already know from inside, and act only on the difference between them.
Why it helps
Acting on an outside account alone is why you keep being surprised. Comparing it against what you already know usually shows you exactly where it is wrong.
Take something that currently passes through several systems or people and complete the whole of it in one place today, removing at least two handoffs.
Why it helps
Every handoff is a place your thing stalls for days waiting on somebody. Completing it inside one system usually finishes today what would otherwise take you a fortnight.
Confirm the distance and the footing for one thing today before moving at all, then take it quickly, and allow no fast movement before the confirmation.
Why it helps
Moving fast before you know the distance means missing and being left somewhere you cannot hold. Confirming first is what makes the quick move land every time.
2Lakukan tiga kontak singkat, bukan satu dorongan besar
3Jaga tiap kontak tetap kecil
The Trial
Take a relationship or project you are failing to hold and increase the number of small contact points today rather than the intensity: three short touches instead of one big push.
Why it helps
One big push at something you are losing grip on does not stick and exhausts you. Three small contacts hold far better and cost you almost nothing.
Only use your contact-based method today once the thing you want is actually concentrated, and verify the density before starting.
Why it helps
Running a contact method in thin conditions means you work all day for nothing and start doubting the method. Verifying density first is a five-minute check for you.
2Mulai dari jarak yang sama, lalu bergerak saat aba-aba
3Menanglah dengan kecepatan dan posisi, tanpa kontak
The Trial
Pick two spots, one clearly better, and start from equal distance with another person. On a signal both go for the better one, winning by position and speed with no contact at all.
Why it helps
Three seconds of genuine competition that costs nothing and nobody gets hurt.
Accept today that one thing you do has no cheap mode, price it honestly, and plan the rest of your day around that cost rather than hoping it drops.
Why it helps
Hoping something expensive will get cheaper means planning a day that does not work. Pricing it honestly once means the rest of your day actually fits.
Add something real to a shared pile today and accept losing one thing to it: contribute to the group document, the communal fund, the shared kitchen, and let one of your own items go into common use.
Why it helps
Expecting a shared arrangement to cost you nothing means you leave the first time it does, and lose the protection too. Accepting one loss keeps the whole thing working.
Converge today on the same signal as someone unrelated who makes the same genuine claim, rather than inventing your own.
Why it helps
Inventing your own signal means teaching every predator separately and paying for it. Converging with someone making the same claim halves the cost for both.
In advance, agree with two consenting people on one fixed feature in a park, such as a bench, a gate or a notice board, and an exact minute to meet there. Each of you starts from a different entrance or corner of the park, at least five minutes' walk from the landmark and from each other along park paths; whoever arrives first props their phone at the landmark, starts recording, holds a watch or clock up to the lens, and stays with the phone while the other two arrive, and all three hands must be on the landmark within one minute of the agreed time.
Why it helps
A tiny, dependable meet-up that gets three people in the same place.
Take the input other people throw out, the stalks, the stale bread, the offcuts, the scrap wood, and turn it into something genuinely good. Show the discards as they were headed for the bin, then the process, then the finished thing being used or eaten.
Why it helps
You read resilience as putting up with more, which just costs you. The version that pays is being able to use the input everyone else writes off, because that supply is cheap and nobody is competing for it.
1Letakkan satu makanan di atas pemanggang luar ruang
2Jaga panas tetap stabil dan amati perubahannya
3Masak hingga matang dan siap dimakan
The Trial
Use an established outdoor grill, barbecue, or permitted cooking fire. Cook one simple food from raw or cold to ready-to-eat without starting an uncontrolled fire.
Why it helps
Turns heat-reading into a concrete outdoor cooking challenge.
Cool something hot using only air and surface area, with no ice, no water and no fridge: spread it thin, pour it between cups, widen the dish, use a draught. Show the starting heat, the method, and the cooled result.
Why it helps
Your first instinct for a problem is to spend something on it. Solving it with surface and airflow instead costs nothing and keeps working when the thing you would have spent runs out.
2Biarkan di udara bergerak selama lima belas menit
3Bandingkan dengan yang tidak dibungkus
The Trial
Wrap one sealed room-temperature drink container in a damp cloth and place it in moving air for fifteen minutes, then compare it with an unwrapped container.
Why it helps
You turn tiny thermoregulation into one concrete experience with a visible finish.
1Pasang cahaya ponsel redup di sudut jauh di belakang Anda
2Matikan lampu, duduk diam selama sepuluh menit
3Salin kata itu setelah kartunya dibalik
The Trial
Before the lights go off, set one phone showing a plain white screen at minimum brightness in a far corner behind you, facing the wall, as a fixed faint light, and check it stays on. A consenting helper writes a random word in thick black marker on white card out of your sight and props it face down on a chair two metres in front of you, then sits beside it. Sit still with the room lights off, and after ten minutes the helper silently turns the card over from their seat; copy the word in thick marker onto a pad in your lap, then switch on the light and hold the pad beside the card.
Why it helps
A calm ten minutes in the dark that shows how much your own eyes can recover.
1Perhatikan satu gerakan mahir dari orang tepercaya
2Tiru sekali, setepat yang Anda bisa
3Baru setelah itu ubah sesuka Anda
The Trial
Choose one safe useful technique demonstrated by a trusted person or reputable tutorial—folding, keyboard shortcut, cooking cut, drawing stroke, tool setup, or similar—and copy it once as exactly as you can before changing anything.
Why it helps
You gain one concrete micro-skill and practise observation before premature improvisation.
10 minDifficulty 2
Copy One Striped Pattern Down Two Separated Chains
Draw a simple pattern of black, white and chestnut bands on a small card, then lay a string or ribbon across the table as a river and make five copies on each bank, copying as faithfully as you can and never changing anything on purpose. The first copy on each bank is drawn from the original and every later copy only from the card just before it on the same bank, each glanced at for ten seconds and then turned face down; keep the other bank covered with a sheet while you work, and finish by turning every card face up and circling one difference between the two last copies that is not in the original.
Why it helps
A calm drawing game that shows, on the table in front of you, how groups that stop mixing slowly turn different.
Choose one current online trend or format. Identify three recognizable features, reproduce those features in a new piece of your own, then change at least one major element such as subject, setting, punchline, visual style, or sound before posting.
Why it helps
Uses social imitation as a learning mechanism while still requiring an original transformation.
1Tanya atau amati hal pertama yang dilihat pengambil keputusan
2Perbaiki satu hal itu hari ini
3Biarkan yang lainnya tetap seperti semula
The Trial
Find out which single thing the person deciding actually looks at first, by asking them or by watching, then improve that one thing today and leave the rest exactly as it is.
Why it helps
You polish the parts you enjoy and the decision turns on something you never touched. Finding out what they actually check takes one question and redirects all your effort to where it counts.
Pick one thing you have copied the surface of without copying how it is built. Study its internal structure today, then rebuild your version so one structural element genuinely matches.
Why it helps
Copying the look of something good without its structure gives you a version that falls apart under use, and you blame yourself rather than the copy. Matching one structural element is what makes it hold.
3Tahan keinginan untuk memperbaiki atau mengubahnya
The Trial
Find the one thing of yours that is currently working and simply do it again today, unchanged, rather than improving it. Repeat it exactly and resist every urge to vary it.
Why it helps
You reinvent things that are working because repeating feels lazy, and the variation usually makes them worse. Repeating exactly is the cheapest output you will ever get.
Commit to one thing today before it is certain, change your line partway through as it moves, and return to a position you decided on before you started.
Why it helps
Waiting for certainty before committing means the thing has gone, and committing without a chosen landing leaves you stranded. Correcting on the way is what makes going early safe.
Place a coin or target behind a clear glass of water and compare where it appears from two angles, then mark the corrected line of sight. Photograph the setup.
Why it helps
Makes refraction tangible and trains the habit of correcting perception when the apparent position differs from the real one.
2Kurangi satu bagian nyata dari biaya itu hari ini
3Buat menunggu jadi lebih murah
The Trial
Work out what one week of waiting currently costs you on something you are holding out for, in money, time or attention. Then cut that running cost by one real thing today so that waiting gets cheaper.
Why it helps
When waiting is expensive you take the first offer rather than the right one. Cutting the running cost of waiting buys you the ability to hold out, which is usually worth more than the offer itself.
Lay forty coins in a counted row. Stick one note to a smooth door or window, clip a small sandwich bag to its lower edge with a paper clip so the load hangs down along the surface, and add coins one at a time from the row until it slips; if it still holds when the row runs out, record the count as 40+ and stop. Then stick an identical note flat under a shelf or table edge, clip the bag to its free edge so the load pulls straight away from the surface, and add coins from a fresh counted row until it lets go.
Why it helps
A ten-minute measurement that shows why some tape holds a poster up yet still peels off cleanly.
1Minta seseorang di kejauhan bertepuk keras dalam pandangan Anda
2Hitung ketukan sampai suaranya tiba
3Ucapkan tebakan Anda, lalu ukur dengan langkah
The Trial
Send someone a good distance away, in view, and have them clap hard. Watch their hands, count the beat until the sound reaches you, and call out your distance guess. Then pace it out and show how close you were.
Why it helps
A single reading leaves you guessing. Two imperfect signals plus the lag between them locates a thing precisely, which is how you get position out of information that looked useless alone.
1Minta setiap orang menjawab ya atau tidak secara lisan
2Diam dihitung sebagai tidak
3Tidak semua ya: jangan mulai; tanyakan apa yang mengubahnya
The Trial
Before starting the next group thing today, go round and get an explicit yes or no from every person - out loud, one at a time, with silence counted as a no. If you do not get a full set of yeses, do not start it; ask what would change the no, and leave it.
Why it helps
Starting group things on assumed agreement is why they fall apart halfway and you end up carrying them. One round of explicit yeses takes two minutes and tells you whether to start at all.
1Simpan sepuluh barang sepanjang hari, tanpa catatan
2Di akhir hari, hanya datangi yang Anda ingat
3Biarkan sisanya di tempatnya
The Trial
Put ten things away over the course of today without writing anything down, then at the end of the day recall as many as you can and go to them. Leave whatever you cannot recall where it is.
Why it helps
Measuring yourself only by what you remember hides how much of your effort pays off elsewhere. Seeing what you lost and what it became changes how you count the day.
2Bangun ulang permukaannya dari yang dipakai semua orang di sini
3Selesaikan hari ini
The Trial
Take one thing of yours that stands out because it is made of imported material, a format or a style from elsewhere. Rebuild its surface today out of what everyone around you already uses.
Why it helps
Bringing in a format from elsewhere makes your work the thing people react to rather than its content. Rebuilding the surface from what they already use gets the content looked at instead.
Cover a stretch of ground using movement you are not powering — an escalator, a slope, a bus, a lift, a moving walkway — and spend the whole of it watching rather than looking at anything in your hands.
Why it helps
You see a piece of your commute properly, probably for the first time in years.
Sit comfortably with a large empty bowl held open in your lap. Over ten minutes a helper standing behind you drops ten light pompoms or paper balls from head height at unpredictable moments. Count what lands inside at the end.
Why it helps
Ten calm minutes of stillness with a gentle game attached.
1Letakkan toples lebar dan mulai pengatur waktu enam puluh detik
2Berjalanlah cepat keliling ruangan, satu dari tiap jenis
3Berhenti seketika saat waktu habis
The Trial
Set a wide-mouthed plastic jar or tub on a table and start a sixty-second timer. Move fast round that one room, walking briskly rather than running, and put in as many different kinds of small, unbreakable object as you can, one of each kind, until the timer ends.
Ask a consenting helper to lay eight paper plates in a winding line on the floor, secretly slipping a loose ball of scrunched paper under two of them. Crawl the route on hands and knees, pressing each plate with one hand before any weight goes on it, and skip every plate that crunches.
Why it helps
A gentle, absorbing movement game that trains careful footing.
