Explaining what voters try to hide | MIT News
New research suggests a voter polling method known as conjoint analysis can get traction on political questions that are hard for traditional surveys to assess.
news.mit.eduHere’s a concise update on the latest about conjoint analysis.
- What it is now: Conjoint analysis remains a leading market-research method for uncovering how people trade off product features, price, and other attributes in realistic decision scenarios. It’s widely used for pricing, feature prioritization, and market-entry decisions.[3][6]
- Recent trends: CBC (choice-based conjoint) continues to be the dominant approach due to its realism and predictive power, with researchers integrating simulations to assess market shares and revenue impacts.[6][3]
- Practical developments: Vendors emphasize real-time reporting, respondent-friendly designs, and ready-made templates to speed up setup while maintaining statistical validity.[2][4]
- Applications in policy and healthcare: Conjoint and related discrete-choice methods are increasingly used to study patient or citizen preferences and to inform policy or service design.[9][10]
- Example resources: Introductory guides and overviews explain design choices (CBC vs other forms), respondent burden, and interpretation of results for decision-making.[5][3]
Illustration: A typical CBC study presents 8–12 product profiles across several choice tasks, asking participants to select their preferred option in each task. This yields part-worth utilities for each attribute level, which can be used to simulate market shares and price sensitivity under different scenarios.[3][6]
