Have you ever wondered how Display Logic can be used in surveys to create an effective survey experience for your respondents? By using display logic, you can be sure that your survey respondents are providing accurate and relevant information, resulting in a higher completion rate.

What is Display Logic?

Display logic is a type of survey logic that allows you to display a question based on how the respondent's are answering the previous question. With display logic, you can hide a certain question from the survey until the respondent’s answer the previous question in a certain way. You can use this feature to ask questions to only those participants who meet the relevant criteria. With Display Logic, you can create more comprehensive surveys that are tailored to your respondents’ needs and preferences. By allowing you to conditionally display or hide survey questions, you can create a more personalized survey experience that is both efficient and effective.

Display Logic Vs. Conditional Logic

In the context of a survey, "logic" refers to the rules and principles that govern the way the survey is structured and presented to the respondent. Survey logic includes a variety of elements, such as skip logic (the ability to skip or bypass certain questions based on the respondent's previous answers) and display logic (the ability to present relevant questions to the respondent based on how they are answering the previous question).

Skip logic is often implemented using conditional statements, such as "if-then" statements, which allow the user to specify certain conditions that must be met in order for the skip logic to be activated.

Display logic, however, does not use conditional statements such as "if-then". It is entirely dependent on the answer to the previous question. Unlike skip logic, display logic does not skip over any questions or sections of the survey. Instead, it simply hides or shows certain questions or sections based on the criteria you have established.

Consider this simple example:

Imagine you are collecting a customer satisfaction survey, and one of your questions asks, "How would you rate our product on a scale of 1 to 5?". Now, as a manager, you'd like to know why consumers rated your product below 2. So here comes the display logic in action, where you can add a display logic, setting the conditions that if the consumer rates the product below 2, display a question asking the reason for their dislikeness.

Why is display logic important in surveys?

Display logic is important in surveys because it plays a key role in the respondent's experience of completing the survey. Effective display logic can make the survey easier to understand and complete quickly, which can increase the response rate and the overall quality of the data collected.

It helps in creating a logical flow for survey takers to ensure that the survey is well-structured. A well-structured survey can be more engaging for the respondent, which can increase their motivation to complete the survey and provide more thoughtful and accurate responses.

What are the advantages of using Display Logic?

  • Identify the participants for whom the questions would be appropriate.
  • Limits the number of questions to be answered in your online surveys.
  • Create surveys that are more relevant to your audience and get better results.
  • Create a more personalized survey experience that is both efficient and effective.
  • It makes online surveys much quicker to answer for respondents.
  • It is simple to use and will help you create a more user-centric experience.

When to use Display Logic?

  • In order to target a specific question to a particular audience.
  • In order to customize the form according to the respondent.
  • In order to obtain more transparent responses.
  • Depending on the conditions, you want to control whether questions are displayed or not.
  • Collects relevant questions and results for more accurate analysis.

Best practices for using display logic in surveys

  • Keep it simple: Use clear and concise language and avoid using overly complicated display logic rules.
  • Use consistent formatting: Use consistent formatting throughout the survey to create a professional and cohesive look, even when display logic is being used.
  • Avoid using display logic to obscure data: Avoid using display logic in a way that might obscure or hide important data from the respondent.
  • Test the survey: Test the survey with a small group of users to get feedback on the display logic and make any necessary changes before launching the survey to a wider audience.

How to Set Display Logic in Block Survey?

1. Select the question where you want to enable the display logic and click on the “Logics” that appears below your question.

2. Next click on “Display Logic” select the question and add the desired condition that you want to apply to the question. You can also add/remove multiple conditions using the plus and delete icons.

3. Test the display logic to ensure that it is working as intended. This may involve previewing the survey and verifying that the correct questions are displayed based on the criteria you have set.


Overall, display logic is a valuable technique for creating a more efficient, personalized, and effective survey experience. It allows you to easily modify or customize the survey experience for different respondents, based on their answers or other factors. It ensures that respondents only see and answer questions that are relevant to them, and display logic can help to improve the quality and relevance of the data collected.
