The document summarizes a study on how consumers respond to different methods of having interests inferred, deduced, or volunteered. It found that:
1) Consumers prefer being asked directly what interests them rather than having companies make assumptions based on their data.
2) Services that asked consumers to voluntarily provide interests through fun and engaging methods, like games or quizzes, performed best.
3) Simply inferring interests from browsing or shopping history was less preferred, and deducing interests from loyalty programs was least preferred. Consumers want more control over their data and interests.
