When To Use Conjoint
Conjoint questions support choice-based preference experiments in social science research surveys. Use them when respondents should compare alternatives made from randomized attributes, such as candidates, policies, products, jobs, messages, neighborhoods, or institutional profiles.
Block Builder: Conjoint
A conjoint task is strongest when each attribute and level maps to a clear research hypothesis. Keep the table readable so respondents can compare alternatives without fatigue.
How It Supports Research Design
- Alternative columns represent the options respondents choose between.
- Attribute rows define the features shown for each alternative.
- Level options are randomly drawn for each respondent task.
- Uneven level weights let researchers sample some levels more often when the design requires it.
- Row and column order controls help reduce presentation effects.

Step 2: Add the question. Choose Conjoint from the question type selector.
Step 2: Choose Conjoint question type
Step 3: Name alternatives. Label the columns, such as Candidate A and Candidate B, so respondents understand what they are comparing.
Step 3: Name alternatives
Step 4: Add attributes and levels. Add each attribute row and at least two level options for that attribute.

Step 5: Set display controls. Turn on attribute names, row order controls, column order controls, or level weights only when they match the randomization design.

Data And Export Notes
Conjoint exports the selected alternative and the assignment information needed to analyze which levels were shown. Preserve the design once live data collection begins. If the conjoint appears inside a larger experiment, use experimental conditions to control which blocks respondents see.
