A trivia question has one job: let a player who knows the topic feel smart, and let a player who does not feel the answer was fair. Most bad questions fail that test in small ways. They are vague, they have two defensible answers, or the wrong options are so silly that nobody is tempted. This guide covers how to avoid those problems, using principles from university assessment guidance on multiple-choice writing, adapted for quizzes and game nights.
What makes a good trivia question
Teaching centers that publish item-writing advice agree on a few basics, and they carry over to trivia almost unchanged.
- Unambiguous wording. Guidance from the University of Waterloo says the stem (the question part) should state the whole problem so a person could answer it without looking at the options. If players need the choices to figure out what you are asking, rewrite it.
- One best answer. Waterloo also advises making sure one option is clearly the best, not merely a little more correct than the others.
- No tricks. The same guidance warns against questions that depend on misleading phrasing or unimportant details. A question that catches people on wording tests reading, not knowledge.
- No unnecessary words. The UW-Madison guide, adapted from Vanderbilt's Cynthia Brame, recommends cutting irrelevant material from the stem because it can make a test less reliable.
Our recommendation: before you finalize a question, ask one other person to answer it out loud without options. If they give a different reasonable answer than the one you planned, the question is not ready.
Good and bad questions side by side
These pairs are our own examples. Each one shows a common mistake and a repair.
| Mistake | Bad version | Better version |
|---|---|---|
| Ambiguous criterion | Which country is the biggest? | Which country has the largest land area? |
| Unfair trick | How many months have 28 days? (Answer: all twelve) | Keep it, but present it as a riddle, not a knowledge question |
| Vague stem | Which of the following statements is correct? | Which ocean borders the west coast of the United States? (a clear question the player can answer before seeing options) |
| Catch-all option | Options: A, B, C, or "all of the above" | Use four specific, parallel options |
| Negative stem | Which of these is not a planet? | Which of these is a planet? (or, if you must use a negative, capitalize NOT) |
| Time-dependent fact | What is the most populous country? | Which country did the UN estimate had the larger population in mid-2023? |
On trick questions: they have a place, just not in a fair knowledge quiz. If you like wordplay, put it in its own round, like our trick questions, where everyone knows the rules going in.
Plausible wrong answers in multiple choice
Wrong options are called distractors, and they do real work. Per the UW-Madison guide, every option should be plausible: it should attract someone who does not know the answer and be ignored by someone who does. The guide also notes that common mistakes are the best source of distractors.
Here is a simple example. A weak question: "What is the capital of Australia? (a) Canberra, (b) Banana, (c) Paris, (d) Tokyo." Nobody is tempted by three of those. A better version uses other well-known Australian cities: Sydney, Melbourne, Canberra, Perth. According to Britannica, Canberra became the seat of federal Parliament only in 1927, when it moved from Melbourne, so the confusion is understandable and the distractors are fair.
More rules from the same guidance:
- Keep options similar in length and grammar. The UW-Madison guide notes that options should match the stem grammatically and run about the same length, otherwise the longest or most detailed one gives the answer away.
- Avoid "all of the above" and "none of the above." Both Waterloo and UW-Madison recommend skipping them, since a player who spots two correct options can guess "all" without knowing the rest.
- Avoid absolute words like "always" and "never" in wrong options. Waterloo notes they are easy to dismiss.
- Order options logically (alphabetically, numerically or by date) so no pattern points to the key. Spread the correct answer evenly across positions a, b, c and d.
- Do not obsess over four options. Waterloo says three work about as well as four or five, mainly because plausible distractors are hard to write. A good three-option question beats a four-option one with a throwaway fourth choice.
Mixing difficulty on purpose
Assessment researchers measure difficulty as the share of people who answer correctly. The University of Washington's guide labels an item easy at 85% correct or above, moderate between 51% and 84%, and hard at 50% or below. It lists an ideal of about 74% for four-option items when the goal is to tell stronger test-takers from weaker ones.
That figure comes from classroom testing, so treat it as a reference point, not a rule for parties. A game is meant to be fun, and a table of friends will not want a test. Our rule of thumb for a 20-question quiz:
- About 6 easy questions that most players can get, so everyone scores.
- About 10 medium questions where knowing the topic pays off.
- About 4 hard ones that separate the experts.
Adjust the mix to your crowd. A family night leans on our easy trivia; a competitive team night can lean toward hard trivia. If you are not sure how hard a question is, test it on two or three people before the event.
Fact-check every question
A wrong answer key does more damage than any wording problem. It makes the host look careless and starts arguments. Build a habit of checking each fact before it goes in.
- Do not rely on memory. Look up the answer even when you feel sure.
- Go to the original source. Caulfield and Wineburg, writing in American Educator, describe "lateral reading": leave the page you are on, open new tabs and see what other reputable sources say. They also advise tracing a claim back to where it started and checking whether that source really supports it.
- Use two sources for anything sensitive such as dates, numbers, records and rules. This is our recommendation, not something the sources prescribe.
- Check the exact wording. "Largest by area" and "largest by population" are different questions with different answers.
Numbers need extra care
Figures differ by source, by year and by definition. The UN's population policy brief from April 2023 gives about 1,429 million people for India and 1,426 million for China in mid-2023, and it says the timing of India passing China is approximate and may be revised as more data arrive. A gap of roughly three million people in a population of over 1.4 billion is thin, so a question built on it should say who made the estimate and when.
Facts that change
Records, rankings, populations, title holders and "latest" anything can go out of date. Our recommendation:
- Add a date or source to the question itself, such as "as of mid-2023, according to the UN."
- Prefer facts that cannot change, such as historical events with settled dates.
- Keep a note of when you last verified each question and recheck changeable ones before every event.
The order of your questions
Does easy-to-hard order matter? A Learning Scientists summary of research by Weinstein and Roediger reports that question order did not change how well students actually scored, but students who started with hard questions rated their own performance as worse. For a game, that second point matters, because mood drives enjoyment.
Our rule of thumb:
- Open with one or two easy questions so players settle in.
- Put the hardest questions in the middle, not at the start.
- Finish on a question most people can enjoy, or a fun tie-breaker.
- Alternate topics so nobody sits out three questions in a row.
- Keep the same format within a round, so players do not have to relearn the rules each time.

Pre-flight checklist
Run each question through this list before it goes into a quiz.
- Can someone answer it without seeing the options?
- Is there exactly one defensible correct answer?
- Does the wording avoid tricks, double meanings and unneeded detail?
- Did you verify the answer in at least one reliable source, and two if it is a date, number or record?
- If it can change, does the question include a date or source?
- Are all wrong options believable, and similar in length and style to the right one?
- Did you avoid "all of the above," "none of the above" and unnecessary negatives?
- Is the correct answer position varied across the quiz?
- Does the quiz mix easy, medium and hard questions in a sensible order?
- Has someone else tried it?
Frequently asked questions
How many multiple-choice options should a trivia question have?
Three to four is plenty. The University of Waterloo says three options work about as well as four or five, because it is hard to write distractors that are all plausible.
Are true/false questions a good idea?
They work for quick warm-ups, but a player can guess right half the time. If you use them, make the statement unambiguous and the fact easy to verify.
What should I do if players dispute an answer?
Show the source you used. If the question was ambiguous, accept the reasonable alternative and fix the question for next time.
