Uncertainty
Stand at the unopened door and write what it is like not to know.
Quick answer: Learn to write poems about uncertainty: open-ended imagery, craft moves, mistakes to avoid, exercises and prompts in this free guide by Writory for poets.
What this theme is
Uncertainty in poetry is the art of the threshold. Where a doubt poem questions something it once believed, an uncertainty poem faces what has not yet happened: the scan results due on Thursday, the visa application, the pregnancy test on the edge of the sink, the country deciding its future overnight. The material is suspense without a genre plot, and the poem's job is not to end the suspense but to render, exactly, what living inside it feels like: the bargaining, the superstition, the way time thickens.
Uncertainty is also a way of writing, not just a subject. A poem can perform not-knowing in its syntax, correcting itself mid-line, offering two versions of the same image, trailing off where a conclusion should be. Done well, this is not sloppiness but mimesis: the shape of the poem becomes the shape of a mind that cannot yet see round the corner.
Why poets return to it
Poets take on uncertainty because it is the actual texture of most human life. We spend very little time in triumph or catastrophe and a great deal of time waiting to find out which one is coming, yet waiting is badly underwritten. The poet who describes a hospital corridor at 4 p.m. with real precision is documenting the common country everyone lives in and almost no one names.
There is a craft dividend too. Writing uncertainty trains you out of the habit of the summarising final line, which is the most common weakness in developing poets, and teaches endings that open rather than close.
Where it comes from
Keats gave the theme its founding principle when he described negative capability, the strength to stay in mysteries without irritable reaching after fact. A century and a half later, Elizabeth Bishop built a whole style on visible hesitation; her poems famously correct themselves as they go, trying one description, then a better one, so the reader watches a mind measure the world rather than pronounce on it.
The Polish poet Wisława Szymborska made not-knowing a moral position, writing in praise of the words I do not know and building poems from questions that history had answered too confidently. In older traditions, oracle and divination poetry, from Delphi to the I Ching, shows how long humans have gone to verse precisely when the future would not speak plainly.
The elements that carry it
- Waiting rooms, platforms, departure boards and letterboxes give uncertainty its natural architecture.
- Fog, mist, and the blurred edge of a map, the old cartographers' unknown regions, supply its weather.
- Unopened things, envelopes, doors, test results, buds before flowering, hold the future in a single image.
- Forked paths and junctions make the branching of possibility physical.
- Suspended motion, a held breath, a coin still spinning, a kettle just before the boil, gives the theme its tempo.
Techniques that work
- Let the poem correct itself on the page, it was grey, no, greyish-green, so the reader watches perception being negotiated rather than reported.
- Write in present tense from inside the waiting, and resist the flash-forward that tells the reader how it turned out.
- Offer two futures in parallel images, the ward and the nursery, the acceptance and the rejection letter, and give them equal sensory weight.
- Use line breaks to suspend meaning, ending lines where the sentence could still go two ways, so the syntax itself hesitates.
- Be exact about what is unknown. Precision about the question, which Thursday, whose handwriting, what number, is what separates uncertainty from vagueness.
Mistakes to avoid
- Mistaking vagueness for uncertainty. A poem that is fuzzy about everything communicates nothing; be concrete about the situation and uncertain only about its outcome.
- Resolving the wait in the final stanza. The phone call that ends the poem usually ends its power too; stop while the coin is still in the air.
- Leaning on fog and crossroads alone. These images are worn smooth; find uncertainty in fresher places, a buffering screen, an unsigned form, a half-packed suitcase.
- Hedging every line until the poem dissolves. Perhaps and maybe are strong spices; use them twice, not twenty times.
An exercise
Recall a time you waited at least a week for news that could change your life. Write a poem set on one single day in the middle of that wait, naming the day of the week, one meal, one superstition you invented, and never revealing what the news turned out to be.
A challenge
Write the same eight-line poem twice: first as if the hoped-for outcome arrived, then as if it did not, keeping six of the eight lines identical. Study which two lines had to change; that difference is your real subject.
A prompt to start from
Write a poem spoken to an envelope, a voicemail, or a message that has arrived but not yet been opened, in the minutes the speaker deliberately delays opening it.
Before you submit
- The unknown thing is named precisely: what question, what date, what stakes.
- The poem stays inside the waiting; no outcome is smuggled into the last lines.
- Hedging words appear no more than two or three times, each earning its place.
- At least one image holds the future physically: something unopened, unfinished, or suspended.
- The final line opens outward instead of summarising.
