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 2,521–2,580.
Sit still somewhere with a lot going on - a street, a kitchen, an office - and cup your hands behind your ears to widen them. Stay for ten minutes, moving nothing, and write down every distinct sound you can place, with roughly where it came from. Only then get up and act on the most useful one.
Why it helps
Moving before you have gathered information is why you keep acting on the wrong thing and having to redo it. Ten still minutes of listening usually changes what you do next.
Press a radial pattern of at least eight ridges into a tray of sand or salt once with a fork. Visit it three times, at the start and five and ten minutes later: each visit, drop five dried lentils onto the circle from a hand-width above, pick out every lentil with tweezers, and add one shell fragment, bead or button to the top of each ridge.
Why it helps
A calm, pleasing rhythm of small returns that trains patience and precision.
Take something already in motion that you cannot stop or restart, and steer it with one small asymmetric adjustment rather than trying to take control: emphasise one side, delay one part, add weight to one option. Make the single adjustment today.
Why it helps
Trying to take control of something already moving usually breaks it. One small asymmetric nudge changes where it lands without stopping anything, and you can do it today.
Out of your sight, a helper puts a ping-pong or paper ball inside some but not all of eight cardboard tubes, tapes them into a loose bundle pointing different ways and writes the number loaded on a folded note. For each tube in turn, drape a small towel over one end as a tent, gathered loosely round the opening, then push a chopstick in from the other end to flush out anything inside.
Why it helps
A clever, playful puzzle that makes a two-part hunting trick click.
Float one large leaf, such as lettuce or cabbage, on a bowl of water. Gently rest five objects on it one at a time, from a feather or paper scrap up to a metal spoon or a stone, and sort them into a 'holds' pile and a 'sinks' pile.
Why it helps
A calm little experiment that shows how weight, not size, decides what a surface holds.
Use a UV-safe household fluorescence example if already available, or a phone-screen simulation if not, and document two plausible functions the glow could serve without declaring either proven. Photograph the setup.
Why it helps
Practises scientific restraint by exploring multiple plausible explanations for a striking trait while preserving genuine uncertainty.
Identify the dependency that actually sets how far you can operate today, and state the radius it gives you.
Why it helps
Your distinctive feature gets all the attention while an unnoticed dependency sets how far you can go. Naming the radius tells you what to plan inside.
Use a wire cooling rack, or a piece of cardboard with rows of holes poked through it with a pencil, as the frame. Each of three builders weaves ten paper strips or straws through the frame so they overlap into one dense thatched canopy.
Why it helps
A shared making task that gets a household working with their hands together.
The next time something goes wrong today, do not announce it. Act on it immediately and let the action itself be visible to the people who need to know, so the warning and the response are the same event.
Why it helps
Announcing a problem before acting on it wastes the minutes that mattered and makes people doubt you the next time. Acting visibly warns them and fixes it at once.
1Ask several people for their direction, no discussion
2Average what they said
3Go that way
The Trial
Collect several people's preferred direction on one decision today without discussion, average them, and go that way.
Why it helps
Discussing a direction means the loudest person decides and you get resentment either way. Collecting and averaging silently gets a better answer and no argument.
Set up one permanent arrangement today supplying what your main source lacks, and make it something handed on rather than re-established each time.
Why it helps
Going out to make up what your main source lacks means doing it again every time and sometimes not at all. A permanent arrangement passed on removes the gap for good.
Name three things you currently do in three separate places or systems. Bring all three onto one surface today, a single notebook, board or room, and run them from there for the rest of the day.
Why it helps
Running three things from three places means you spend most of your attention switching and lose track of all of them. One surface for all three makes the whole load visible at once.
Commit to one method for a task today and repeat it many times rather than switching between approaches, noting how the tools have shaped to it.
Why it helps
Switching methods every time one is awkward means never getting good at any and your tools stay generic. One method repeated wears everything into fitting it.
Leave one thing deliberately unstable today and steer it with constant small corrections rather than making it stable, and note how much tighter it turns.
Why it helps
Making something stable so it needs no attention also means it will not turn when you need it to. Leaving it unstable and correcting constantly gets you the manoeuvrability.
Put the store for one thing inside the place you already shelter today, enough to cover a stated stretch with no trips out, and state the stretch.
Why it helps
Keeping your store somewhere other than where you shelter means a trip out on exactly the day you cannot make one. Putting it inside removes that trip for good.
Take one thing you do on a schedule. Check today whether the conditions it assumes are actually present, and if they are not, change what you do rather than keeping the date.
Why it helps
Running on a schedule you set for conditions that no longer apply makes you confidently wrong, which is worse than being unprepared. Checking the ground once a season is all it takes to catch it.
Find one thing you maintain permanently for appearance, a profile, a title, a possession, a presence, and either use it today for its actual purpose or stop paying for it.
Why it helps
You pay all year for signals you use for seconds, and you have never added the cost up. Naming it means you either start using one or stop funding it.
Build a genuinely cheap off state today for something you run expensively, and actually enter it rather than idling.
Why it helps
Idling something expensive still burns most of the cost for you while producing nothing. A genuinely cheap off state is what makes the expensive mode affordable.
Take a decision you made earlier under different conditions and re-check it against where things actually are now, then adjust the heading rather than the destination. Make one correction today.
Why it helps
Decisions made under old conditions quietly stop pointing where you wanted. Correcting the heading while keeping the destination costs ten minutes and saves you arriving somewhere you never chose.
2Spend time on it that achieves nothing measurable
3No practical purpose mixed in
The Trial
Take one relationship you have been running efficiently. Spend time on it today in a way that achieves nothing measurable at all, and do not combine it with any practical purpose.
Why it helps
Running a relationship efficiently means every interaction of yours has a purpose and the person can feel it. Time that achieves nothing is the only kind that actually builds anything there.
Do one thing today at a specific angle or position you worked out first, repeating the positioning until it lands rather than putting more effort into it.
Why it helps
Putting more effort into something that is simply aimed wrong gets you nothing and tires you out. Finding the angle first means ordinary effort suddenly works.
Take something you keep trying to improve and check whether that is actually what limits the result. Measure or ask, find the real bottleneck, then spend your effort there instead for one session.
Why it helps
Improving the part you are comfortable with feels productive and changes nothing, because it was never the limit. Finding the real bottleneck usually takes an hour and redirects months of wasted effort.
Set up one visible indicator today that tracks your actual state automatically, so nobody has to ask how things are going.
Why it helps
People asking how things are going costs you the same explanation repeatedly. An indicator that tracks your state automatically answers it before they ask.
Name one thing you do because people in your category do it. Stop doing it today, do the task its own way instead, and state what you are no longer going to do.
Why it helps
Doing things because people in your category do them means you carry costs that were never yours and never notice. Dropping one shows you how much of your work was inherited rather than needed.
Set the level you are working at once today, the depth of detail, the scope, the standard, then cover ground at a constant rate without adjusting it.
Why it helps
Adjusting your level as you go means inconsistent work and constant decisions. Setting it once and sweeping covers far more ground at the same quality.
Take something that looks fine and inspect its interior today rather than waiting for symptoms: open the file, check the logs, ask the quiet person, look under the cover.
Why it helps
Waiting for symptoms means you find out when it is already unrecoverable, every time. One scheduled look inside something healthy is the only way you catch it while it is still fixable.
Give one genuinely useful find out loud with enough detail to act on: the exact shop and shelf, the exact setting, the exact page. Say it as directions, not as a vague recommendation. Then show it really sent to the group chat.
Why it helps
A find you keep to yourself dies with you. Passing it on precisely enough for someone to act on turns one piece of luck into everybody's, and it comes back to you later.
Plan the descent from something you have raised today, the step down, the handover, the return to normal, before you do any more raising.
Why it helps
You prepare for the climb and get hurt on the way down, because nobody plans that part. Naming the buffer first is what makes the whole thing survivable.
Build one defence today that only activates once something has committed against you, then do nothing until it does.
Why it helps
Acting before anything has committed means spending on threats that were never going to arrive. A defence that fires on their commitment costs you nothing.
Look honestly at what you have been consuming most of in one area today, then change one input deliberately for the rest of the day and name what you expect it to show up as.
Why it helps
What you take in steadily shows up in you whether you chose it or not, and by the time it shows it is expensive to change. Swapping one input now decides something about you later.
Pick the thing you always do at the last minute and do the closing part now: pack the bag, prep the food, fill the form. Show the mess, the work, then the sealed thing put away. Say the date it is actually due.
Why it helps
The deadline is always later than the point where the work is still easy. Closing it off while conditions are mild buys back the panicked hour you would otherwise spend.
Try to open something genuinely hard with your bare hands, and let the failed attempt stand. Then take it up to real height and drop it onto a hard outdoor surface, clear of feet and windows. Show the pieces it broke into.
Why it helps
Effort is not your only lever. When grinding has stopped working, changing the conditions beats trying harder, because most stuck problems turn out to be height problems rather than strength problems.
Give one sensor or monitoring arrangement of yours a second useful function today, so it is justified even when nothing is detected.
Why it helps
A monitoring arrangement that only pays off when something happens is the one you cut in a quiet month. A second function means it is always worth your keeping.
Work today along the edge of something you know rather than in the open middle of something you do not: the adjacent problem, the familiar client, the neighbouring skill.
Why it helps
Striking out into the open middle means working without information and calling it courage. Moving along the edge of what you know gets you just as far with feedback.
2Split them into separate days, accounts or spaces
3Keep both going after the split
The Trial
Take two of your own efforts that are quietly consuming each other, time, attention, budget, and physically separate them today: different days, different accounts, different spaces.
Why it helps
Two of your own efforts sharing the same pot means one quietly eats the other and you blame yourself. Separating them structurally lets both survive.
Put the strongest protection you have today onto what you are leaving behind rather than onto yourself, and name what you leave unprotected.
Why it helps
Protecting yourself first means what you leave behind is the thing that gets destroyed. Concentrating it on the output is what makes the work outlast you.
Launch a paper plane, leaf or seed head into real moving air, by a fan or outdoors, and let go completely. Keep trying angles until one stops dropping and starts gliding. Follow the best run to the end.
Why it helps
Most exhaustion comes from fighting momentum that was already going your way. Find what is moving anyway and attach to it, instead of generating all the force yourself.
Name the one or two parts of a situation today that cannot be concealed, manage exactly those, and stop working on anything already invisible.
Why it helps
Spending effort hiding what was already invisible means the two things people notice about you stay untouched. Naming those and dealing with them is the whole job.
Act today as a fixed small group on one thing rather than as individuals coordinating, and make the group the thing that holds the position.
Why it helps
Coordinating individuals each time means you pay the overhead again on every occasion and someone is always missing. A fixed small group simply arrives already working.
Make the first contact with one thing today a grip rather than a touch, committing fully on the first attempt with no exploratory approach.
Why it helps
Testing something with a light first touch warns it and the real attempt never comes. Making the first contact hold means one attempt is all you need to spend.
Set aside one visible reserve today that lets you stop during a bad stretch, and state the length of stretch it covers rather than leaving it vague.
Why it helps
With no reserve you have to keep working through the worst conditions and you lose more than you earn. A visible one you can measure turns stopping into a choice.
Hand off one responsibility completely today, including a part you are expected to keep, and spend the freed effort on the thing you are strongest at.
Why it helps
Keeping a responsibility because you are expected to means your strongest work is what gets squeezed. Handing it off entirely puts your effort where it actually pays.
Pick one process of yours that lets small things through. Make its filter finer today, lower one threshold, and capture a real example of something that would previously have passed straight out.
Why it helps
A coarse filter loses the small things continuously and you never see what went, because it left without a trace. One lowered threshold shows you what you have been dropping all along.
