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 841–900.
The Trial
Name one general-purpose ability you maintain badly and one specific thing you do well. Drop a piece of the general today, put that time into the specific, and say what you are no longer going to be able to do.
Why it helps
Keeping every general ability at a mediocre level is what stops you reaching real depth in the one that pays. Naming what you will no longer be able to do is the part that makes the trade real.
2 minDifficulty 1
The Trial
Name the physical thing that has been nudging you all day: the notification buzz, the chair, the noise, the heat. Then change that one physical input, properly, and show yourself back at work after it. One input, one change.
Why it helps
You look for reasons you feel off and treat it as a mindset problem. Changing the one physical input that has been nudging you all day fixes more of it than any amount of reframing.
1 minDifficulty 4
The Trial
Look at the alternatives to one piece of your work today, then improve yours on the basis of that comparison rather than explaining it.
Why it helps
Defending your work on its own terms means not knowing it is the weakest option on the table. Looking at the alternatives tells you exactly what to change.
2 minDifficulty 3
The Trial
Accept lower efficiency per unit today in exchange for much higher throughput, and state both numbers before choosing.
Why it helps
Chasing efficiency per unit caps how much you can move through, and you never notice the ceiling. Trading some of it for throughput often doubles the total.
2 minDifficulty 2
The Trial
Reorder one process today so the gentle preparatory stage comes before the harsh one rather than after it.
Why it helps
Putting your harsh stage first destroys whatever would have done the gentle work. Reordering it means the same process extracts far more for you.
2 minDifficulty 1
The Trial
Let one process run its full required time today without attempting to shorten it, and name what that patience gives you access to.
Why it helps
Trying to hurry a process that cannot be hurried ruins the output and you still waited. Paying the full time gives you a supply nobody contests.
2 minDifficulty 1
The Trial
Tear ten stamp-sized squares of thin paper and put them at one end of a table, with a bowl thirty centimetres away and a desk fan on low blowing across the path. Using only suction through your own straw, lift each square and carry it into the bowl; any dropped square goes back to the start.
Why it helps
A silly, focused game that turns out to demand real control.
10 minDifficulty 2
The Trial
Prop a piece of corrugated cardboard upright against a wall and set a bowl of marble-sized playdough or salt-dough pellets two metres away across a clear floor. On go, walk briskly to the bowl, take one pellet, return and press it onto the cardboard, building a curved cup rim layer on layer; at least twelve pellets must go on within ninety seconds.
Why it helps
A messy, fast, satisfying burst that tests your legs, hands and structure at once.
4 minDifficulty 3
The Trial
Measure the real distance or delay to something you depend on today, state the number, and adjust what you have committed to so it fits.
Why it helps
Committing to more than your supply distance allows is why you keep falling short and cannot see why. One measurement tells you what you can actually carry.
2 minDifficulty 2
The Trial
Count the ways into one thing today, close every one you do not need, and account for each that remains by name.
Why it helps
With more ways in than you can name, you are defending something you have not mapped and the gap you missed is the one used. Closing down to a countable few ends that.
2 minDifficulty 2
The Trial
Work out today whether a position you are competing for is actually central or peripheral, and withdraw entirely if it is peripheral.
Why it helps
Holding a peripheral position costs you everything a central one costs and returns almost nothing. Checking which you have is a one-hour job.
1 minDifficulty 3
The Trial
Take one high vantage point today, a window, a stairwell, a hill, and spend fifteen minutes reading everything happening below without going down to investigate any of it.
Why it helps
Going down to check everything means you spend the day walking and still miss the pattern. Fifteen minutes from a height shows you which one is worth going to.
2 minDifficulty 1
The Trial
Find or make one genuinely dark place today, in a cupboard, under a table, behind a curtain, and stay inside it doing nothing for fifteen minutes. No light, no screen, no reading.
Why it helps
Hiding somewhere only half dark means you keep being found and never actually rest. Fifteen minutes somewhere genuinely dark resets you in a way a sofa cannot.
2 minDifficulty 1
The Trial
Pick one thing you are waiting on and one place to wait for it. Sit there for fifteen unbroken minutes with no phone, no reading and no task - just attention on that one thing. If it arrives, act immediately and fully. If it does not, the fifteen minutes still count.
Why it helps
Filling every wait with something else means you are never ready when the moment you were waiting for arrives. Fifteen minutes of real attention teaches you that stillness is doing the work.
2 minDifficulty 1
The Trial
Make sure today that each member of one group can actually identify the others by name, and fix it where they cannot.
Why it helps
A group whose members cannot identify each other is a crowd and behaves like one when you need it. Fixing one gap is what makes it a group.
2 minDifficulty 2
The Trial
Climb fifty stairs today without stopping and without using the handrail, placing each foot deliberately on the edge of the step rather than the middle. If you lose the placement, start the count again.
Why it helps
Fighting on flat ground where everyone is equally capable means you win on luck. Moving onto terrain where your grip is better takes the contest away from them.
2 minDifficulty 3
The Trial
Put yourself in a situation today that requires something you have never done, and solve it with what is physically to hand rather than acquiring anything.
Why it helps
You assume you cannot do things you have simply never had to do. One situation with nothing to hand shows you what you actually have.
2 minDifficulty 2
The Trial
Mark a line about halfway up a glass and set it on a surface at least five metres from the tap, with a phone propped where it can see both the tap and the glass. Soak a clean sponge, carry it to the glass over a small bowl to catch drips and squeeze it out into the glass, repeating until the water reaches the line; tip any drips in the bowl away, not into the glass, and mop any spills.
Why it helps
A surprisingly vivid lesson in how much effort a small drink can cost.
15 minDifficulty 2
The Trial
Fill a sink or washing-up bowl with water, then sink a clear plastic cup, turn it upside down underwater so it is full of water and hold it there. With a second cup, trap air at the surface, carry it down and release it underneath the first, repeating trips until the upturned cup is completely full of air.
Why it helps
A satisfying kitchen-sink physics demo you can show anyone in two minutes.
10 minDifficulty 2
The Trial
Take one thing you have been trying to do selectively and slowly. Take in everything available today without filtering, then do the sorting as a separate second step once it is all in.
Why it helps
Judging each item as it arrives slows you to the speed of your decisions and you reject things you would have kept. Taking it all in and sorting after is faster and gets you better choices.
2 minDifficulty 2
The Trial
Move one filter today to the entrance of a process rather than partway through it, and name what cannot be removed later.
Why it helps
A filter partway through means whatever got in before it is now permanent for you. Putting it at the entrance is the only placement that actually works.
2 minDifficulty 2
The Trial
Test first that your phone camera shows a remote's LED as a glow, switching to the front camera if the rear one shows none. Leave the room while a helper hides the remote among cushions in a dim room, with a rubber band holding down the mute button, the LED end uncovered and facing into the room though the rest may be tucked away, and the TV unplugged or out of line of sight. Return and search only through your camera screen; you have sixty seconds to spot the glow and grab the remote, then remove the band straight away.
Why it helps
A quick detective race that shows you light your own eyes cannot see.
5 minDifficulty 3
The Trial
Take something closed you need to understand and probe it from outside today rather than waiting for access: test an input and watch the output, ask an adjacent person, try a small case and see what returns.
Why it helps
Waiting for access to something closed means waiting indefinitely while assuming things about it. Probing from outside gives you a real picture today and usually a more honest one.
2 minDifficulty 1
The Trial
Search for one thing today using the sense that works in the conditions you actually have, and stop using the one the conditions defeat.
Why it helps
Persisting with the sense the conditions defeat means you find nothing and conclude there is nothing there. Switching to one that works turns the same ground productive.
2 minDifficulty 2
The Trial
Wear a blindfold and headphones and sit still in a fully dark room for ten minutes. Just before the time is up, a helper charges a glow-in-the-dark sticker under a lamp in another room and places it somewhere in view of your chair; when the ten minutes end, take off the blindfold and headphones, look around without moving from the chair, and call out the sticker's location aloud, such as 'left of the bookshelf, knee height', before switching the lights on.
Why it helps
A calm experiment that shows how much better your eyes see after waiting in the dark.
15 minDifficulty 1
The Trial
Choose a room with at least two doorways. Try spots slowly, lying or crouching behind cover such as the back of a sofa, until you find one where your eyes clear the cover and every doorway is in view; hold still there and take a photo from your eye level.
Why it helps
A calm few minutes that changes how you see a room you know well.
15 minDifficulty 1
The Trial
Place three familiar small objects inside a bag, close your eyes, and identify one chosen object using touch alone. Keep searching until you can name it before pulling it out.
Why it helps
You sharpen tactile attention and turn patient searching into a small sensory win.
6 minDifficulty 1
The Trial
Have someone hide a scented or sounding household object nearby, then sample from two positions and choose the stronger direction until you find it. Do not search visually first.
Why it helps
You get a concrete, memorable result while practising scent trail as a real human action.
8 minDifficulty 2
The Trial
Compare three nearby safe surfaces or spots for coolness/moisture, choose the best refuge, and place a small non-living token there before photographing the choice.
Why it helps
You know where the cool spot in your home actually is, which matters on the day it matters.
6 minDifficulty 1
The Trial
Place three safe objects in front of you, one slightly warmer than the others. Close your eyes and identify the warm one by holding your hand near each without touching.
Why it helps
You turn sideways strategy into one concrete experience with a visible finish.
10 minDifficulty 1
The Trial
Hide six safe small objects under loose towels, paper or cushions, then uncover them one by one by moving only the top layer currently blocking them.
Why it helps
You turn snout labor into one concrete, visible experience instead of an abstract idea.
10 minDifficulty 2
The Trial
Pick one area of your life that is currently formless. Choose a single fixed, upright point in it today, a set hour or a named commitment, and attach one real thing to that point.
Why it helps
A formless stretch of your life stays formless because nothing has anywhere to attach, and every good intention slides off it. One fixed upright point gives the rest of it somewhere to hold.
2 minDifficulty 1
The Trial
Walk your home or garden with the back of your hand out and find the single dampest, coolest spot in it - behind a pot, under a sink, beneath leaves, in a shaded corner. Then put something there that benefits from it: a cutting, a sponge, a stored root vegetable. Check it tomorrow.
Why it helps
Your home has microclimates you have never noticed, and you keep things in the wrong ones and wonder why they fail. Finding the dampest spot by hand takes five minutes and changes what survives.
2 minDifficulty 1
The Trial
Get through one obstacle today without force: find the existing gap, the quieter route, the person who already has access, and use that instead of pushing. Make no noise about it.
Why it helps
Forcing through obstacles makes noise and attention you did not want. Finding the gap you actually fit through gets you to the same place without anyone registering it.
2 minDifficulty 2
The Trial
Have someone place one small harmless object inside one of five opaque containers. Without opening them, shake each container once and choose which contains the object. Open them only after committing to one answer.
Why it helps
Turns precise sound localization into a fast hidden-target challenge.
5 minDifficulty 4
The Trial
While you are out of the room, a partner lines up eight identical cups, puts one drop of vanilla in a spoonful of water in one cup and marks the underside of that cup with a sticker, puts half that strength in the cups either side, a trace in the next ones out and plain water in the rest. Blindfolded, sniff two neighbouring cups at a time, move toward the stronger side each round, pick the source cup in no more than six comparisons, then lift it and turn it over to show its base.
Why it helps
Your nose turns out to be far better at comparing than at identifying, and now you know how to use it.
10 minDifficulty 2
The Trial
Pick a question you cannot answer from the obvious source and get it from the channel where the answer is loud instead: ask the person who was in the room rather than reading the notes, check the bank rather than the spreadsheet, look at usage rather than opinions.
Why it helps
You keep going back to the source that has never answered this question. Switching to the channel where the signal is strong usually answers it in minutes, and you stop rereading the same unhelpful thing.
1 minDifficulty 3
The Trial
In a safely lit room after dark, find three ordinary useful objects you did not plan to use and arrange them together.
Why it helps
You turn false eyes into one concrete, visible experience instead of an abstract idea.
10 minDifficulty 2
The Trial
Work slowly today using a sense or channel others ignore, and find one thing that faster visual scanning walks straight past.
Why it helps
Scanning fast means you find only what is visible, which everyone else has taken. Slowing down and using the ignored channel finds what they walked past.
2 minDifficulty 2
The Trial
Replace one heavy durable setup today with a light version you expect to rebuild, and rebuild it once rather than reinforcing it.
Why it helps
Building heavy for a steady stream of small returns means your structure costs more than the catch. Light and rebuilt often is what makes it profitable for you.
2 minDifficulty 1
The Trial
Spread a large sheet of paper or thin cloth flat and rest your fingertips on one edge with your eyes closed. Have someone place objects of different weights onto it, one at a time, at different distances. For each one, say where it landed and how heavy it was before opening your eyes.
Why it helps
Taking in information through five channels at once means you trust none of them and act slowly. Learning what one channel can really tell you makes you faster and more certain.
2 minDifficulty 1
The Trial
Walk a safe five-minute route at one comfortable pace and keep that pace through slopes, turns and distractions.
Why it helps
You turn altitude fit into one concrete, visible experience instead of an abstract idea.
10 minDifficulty 2
The Trial
Identify the one decisive mechanism you have today and deliberately slow everything else down because of it.
Why it helps
Being quick at everything hides which of your mechanisms is actually decisive. Naming it lets you slow the rest down without losing anything.
2 minDifficulty 1
The Trial
Move the response to one recurring situation today to the point where it actually happens, rather than routing it through you to decide.
Why it helps
Routing every response through you means nothing happens while you are busy and you are the bottleneck. Putting it at the point of contact means it fires without you.
1 minDifficulty 3
The Trial
Drive one fast action today from something stored rather than from effort applied at the moment, and build the store first.
Why it helps
Driving a fast action from effort at the moment caps it at how fast you can push. Stored pressure released at once exceeds anything you could do live.
1 minDifficulty 4
The Trial
Respond to the next short-lived opportunity today within minutes rather than preparing a better response, and commit immediately.
Why it helps
Preparing a better response to something short-lived means arriving after it is taken. A rough response within minutes gets you the whole thing.
2 minDifficulty 2
The Trial
Tape a length of clear flexible tubing or a wide bubble-tea straw, at least 1 cm across inside, into a J shape with the opening facing up, and drop in a bead no wider than half the tube so it rests at the bottom of the bend. Bend a pipe cleaner into a curve that follows the tube and use it to hook the bead back up and out through the opening.
Why it helps
A fiddly little puzzle that rewards matching the tool to the job.
10 minDifficulty 2
The Trial
Choose one hobby or small project you keep putting off because you have no space for it. Gather everything it needs into a single shoebox or tray, then do one short session of it using only what is in the box.
Why it helps
Waiting for a spare room or a bigger desk is how good plans stay unstarted for years. A complete kit in one small box lets you begin today and pick it up in seconds next time.
2 minDifficulty 2
The Trial
Set five heavy objects you can safely lift - full bottles, books, bags - on the floor around a clear space. Starting with both hands empty, pick each one up and carry it to a single spot, one at a time, gripping hard enough that nothing slips. Do all five in under thirty seconds with a visible timer.
Why it helps
Tentative half-grips are why you drop things and have to start again, in work as much as in your hands. Committing fully at the moment of contact is most of what makes effort stick.
1 minDifficulty 4
The Trial
Finish five tiny jobs in ten minutes today, each one small enough to complete in two, and do not start anything larger until all five are genuinely done.
Why it helps
Holding out for one big win means the small jobs pile up and block everything behind them. Five finished in ten minutes clears your day more than the big one would.
2 minDifficulty 2
The Trial
Get five people to do the same thing at the same hour today rather than spreading it over a week: the same message, the same request, the same arrival. Concentrate it into one window.
Why it helps
Spreading your effort across a week means each piece gets dealt with and dismissed on its own. Concentrating it into one hour overwhelms what would otherwise absorb it.
1 minDifficulty 5
The Trial
Put five things away today in five different places, each chosen deliberately, and write nothing down. Later in the day retrieve all five from memory, going straight to each one rather than searching.
Why it helps
Keeping everything in one place means one bad day takes all of it. Spreading it only works if you can go straight back, and that is what the recall gives you.
1 minDifficulty 4
The Trial
The next time today you notice the opening you have been waiting for - someone free, a door open, a question asked - commit to it inside five seconds and go the whole way, not a tentative version. If you hesitate past five seconds, let it go entirely and wait for the next one.
Why it helps
Half-committing to an opening is worse than missing it, because you spend the effort and lose the chance anyway. A five-second rule forces you to either go properly or save yourself the attempt.
1 minDifficulty 4
The Trial
Send five separate short contact messages today to one person you matter to, spread across the day, each one only a few words and expecting no reply. Do not bundle them into a single long message.
Why it helps
Saving contact up for one big conversation means the bond is cold when you need it. Five cheap messages a day keep the line already open for you.
2 minDifficulty 2
The Trial
Find five details in a familiar place today that nobody around you has noticed, and write each one down. They must be things that require getting into an awkward position or looking where people do not look.
Why it helps
Competing for what everyone can see means you win on effort alone and usually lose. Getting at what others cannot reach gives you a supply nobody is taking from you.
2 minDifficulty 2
The Trial
Pick something you have been trying to do by pushing harder - a run, a long work block, a difficult hour. Today, fix the intake instead: breathe through your nose only for the whole thing, eat or drink properly beforehand, and go slower than feels right. Compare how it goes to your usual effort.
Why it helps
Pushing harder when you are short of oxygen just makes you fail faster, and you read that as weakness. Fixing the intake lets you do more at less cost than any amount of effort would.
2 minDifficulty 1
The Trial
Fix one shared corner today that nobody owns: the communal shelf, the stairwell, the group document. Improve it for everyone who uses it and tell nobody that you did.
Why it helps
Only maintaining what is yours means the shared parts rot and you live among them anyway. One unannounced fix improves the place you actually spend your time.
2 minDifficulty 2
The Trial
Pick one thing you want and have been putting off asking for: a swap, a favour, a straight yes or no. First say out loud what you will do if the answer is no. Then go straight to the person and ask in one clear sentence with no long lead-in, and accept the answer you get.
Why it helps
Requests you keep postponing cost you more in worry than any refusal could. Knowing your fallback first takes the sting out of a no, so you can ask plainly and get your answer today.
1 minDifficulty 3
The Trial
Pick one spot and stay physically fixed there for twenty minutes doing a single task, without getting up for anything. Whatever comes to you in that time, handle it from where you are.
Why it helps
Getting up resets your attention every time, and most of what you got up for could have waited. Twenty fixed minutes gets more done than an hour of moving around.
2 minDifficulty 2
The Trial
Identify one window that is about to close on something today, and put everything you can into it before it does rather than after.
Why it helps
Putting effort in after the window closes changes nothing and you will not be told. Naming the deadline is what makes your input count.
1 minDifficulty 3
