What type of research focuses on what users say about a product?

Attitudinal research is specifically designed to gather insights into what users think, feel, and express about a product. This type of research typically employs methods such as surveys, interviews, and questionnaires to capture users' opinions, beliefs, and preferences. The goal is to understand the motivations and attitudes that drive user behavior.

In contrast, observational research involves watching users interact with a product to glean insights without directly asking them, which does not focus on user statements about their experiences. Content analysis examines existing materials or data to identify patterns or themes but does not elicit direct user feedback. Usability testing assesses how effectively users can navigate a product and identifies any usability issues but also does not emphasize capturing users' verbalized thoughts or feelings.

By prioritizing user expressions and feedback, attitudinal research plays a critical role in informing design decisions and enhancing the overall user experience based on those insights.
