# Conditional Logic

> Show or skip questions based on participant answers to create dynamic, relevant interview experiences

Conditional logic lets you show or skip questions based on how a participant answered an earlier question. This keeps interviews relevant, reduces fatigue, and enables more sophisticated research designs.

***

## How It Works

You set conditions on any question to make it display only when specific criteria are met — based on the answers to earlier multiple-choice or closed-ended questions.

**Example:** Show Question 5 only if the participant selected "Yes" in Question 3.

***

## Setting Up Conditional Logic

1. In the **Editor**, click into the question you want to conditionally show
2. Click **Show advanced settings**
3. Select the earlier multiple-choice question whose answer should trigger the condition
4. Choose the specific answer option(s) that should cause this question to appear
5. Add additional conditions if needed

<Tip>
  Conditions are evaluated in real time as the participant progresses. If a prior answer doesn't meet the condition, the question is silently skipped — participants never see an empty or broken screen.
</Tip>

## Multiple Conditions

You can add multiple conditions to a single question (AND logic — all conditions must be met).

**Example:** Show this question only if the participant is in the US AND selected "Premium" in Q2.

***

## URL Parameters & Recruits

You can also segment sample based on URL Parameters or the recruits in the recruit tab.

**Example:** Show this question only if parameter is "user".

***

## Common Use Cases

* **Concept-specific follow-ups:** Only show questions about Concept A to participants who were assigned Concept A.
* **Experience-based routing:** Ask different questions to customers vs. non-customers.
* **Emotional branching:** Show a "what went wrong?" question only to participants who gave a low rating.
* **Screener reinforcement:** Skip irrelevant discussion guide questions based on screener answers.

<Tip>
  Test all conditional paths thoroughly using **"Run from Start"** or **"Open Preview"** before launching. Trace each path to confirm the right questions appear and none are shown incorrectly.
