What is an advantage of conducting interviews with users?

Conducting interviews with users offers the significant advantage of providing in-depth real-time feedback. This approach allows the researcher to explore users' thoughts, experiences, and feelings in detail, facilitating a deeper understanding of their needs and motivations. During an interview, individuals can elaborate on their responses, share anecdotes, and clarify their viewpoints, creating a rich context that might not emerge in other research methods. This qualitative insight is invaluable for UX design, as it helps inform design decisions and identify user pain points and desires in a way that more quantitative methods may not achieve.

The other options, while they may have some merit in different contexts, do not capture the primary strength of user interviews. Larger sample sizes are often a feature of surveys or quantitative research, while follow-up questions are typically an integral part of interviews rather than something that is eliminated. Additionally, while interviews can vary in cost, they can be more expensive than some methods, especially when considering the time investment required for planning, conducting, and analyzing the results.
