How to write open-ended answers researchers actually use

Most survey questions give you boxes to tick. Open-ended questions give you a blank space and ask you to explain in your own words. They are often the part of a survey researchers read most closely. Here is how to make yours count.

A woman in her sixties types on a laptop at a sunny garden table in Lisbon, a cup of coffee and a small vase of flowers beside her, screen angled away.

Key points

  • Open-ended answers explain the "why" behind the numbers, and research teams read them carefully.
  • Specific details, reasons and examples are far more useful than one-word answers such as "good" or "fine".
  • A few clear sentences are enough. You do not need perfect spelling or grammar.
  • Never include personal details such as your full name, phone number or address.

Why open-ended questions matter

Closed questions, the ones with options to choose from, are great for counting. They tell a company that most people prefer design B. But they do not explain why.

Open-ended questions fill that gap. "What did you like most about this ad?" or "Why did you stop using the app?" invite answers in your own words. Researchers group these answers into themes, pull out quotes that explain the numbers and often share them directly with the people making decisions. A single clear sentence from a customer can change how a team sees a problem.

What makes an answer useful

Be specific

Compare these two answers to "What did you think of the new packaging?"

  • "It was nice."
  • "I liked the bright green, it stood out on the shelf, but the text on the back was too small to read without my glasses."

The second answer gives the designer two things to act on. It names what worked, what did not and why.

Explain your reasons

Whenever you give an opinion, add "because". "I would not buy it because it costs more than the brand I use now and I cannot see what is better about it" tells the researcher far more than "I would not buy it".

Use a real example

Stories are powerful. "Last Saturday I tried to change my delivery slot in the app and could not find the option, so I phoned instead and waited 20 minutes" is exactly the kind of detail that leads to a fix.

Say what you really think

If you did not like something, say so politely and clearly. If you have no opinion, say that too. Honest answers are always more valuable than kind ones.

How long should an answer be?

Usually one to three sentences is ideal. Some questions ask for more, for example "Describe your morning routine", and longer answers are welcome there. If a question asks for a single word, such as the first brand that comes to mind, one word is right.

Do not pad your answers to make them longer. Researchers notice copied text, repeated phrases and filler, and it can lead to a response being removed during quality checks.

Quality checks read your words. Answers such as "good good good", random letters or text pasted from a website are easy to spot, and surveys with answers like these may not be rewarded.

Tips that make it easier

  • Use voice typing. Most phones let you tap the microphone on the keyboard and speak your answer. It is quicker and often more natural.
  • Write in your own language style. Spelling mistakes, slang and short sentences are fine. Researchers care about meaning, not grammar.
  • Answer the question asked. If the question is about price, focus on price, even if you have other thoughts. There is often a later question for general comments.
  • Do not use AI tools to write for you. The whole point is your own view. Answers written by a chatbot tend to sound generic, and they are increasingly easy to detect.

What to leave out

Open-ended answers are read by people and sometimes quoted in reports. Keep your privacy in mind:

  • do not include your full name, email address, phone number or home address
  • do not name other people, such as a friend or a shop employee
  • avoid sharing sensitive details that the question does not need, such as health information

If a question asks you something you are not comfortable answering, many surveys let you skip it or write "prefer not to say".

A quick before and after

Question: "Why did you choose this phone plan?"

Before: "Price."

After: "It was the cheapest plan with enough data for streaming on my commute, and I could keep my number without visiting a store."

The second answer takes ten seconds longer to type and is ten times more useful.

Common questions

Will my exact words be shared with the client?

Sometimes. Short quotes may appear in reports to illustrate a theme, but they are not linked to your name or contact details.

What if English is not my first language?

Write in the way that is most comfortable for you. Many surveys are available in several languages, and researchers are used to reading answers from people all over the world.

Do longer answers earn more?

No. Rewards are set for the whole survey. But thoughtful answers help you pass quality checks and build a good track record, which brings more invitations over time.
