“Chances are that, if you do user research, you conduct a fair number of user interviews. When conducting interviews, our training tells us to minimize bias by asking open-ended questions and choosing our words carefully. But consistently asking unbiased questions is always a challenge, especially when you’re following a participant down a line of questioning that is important, and you haven’t prepared your questions ahead of time. Also, if you do a lot of interviews, you might fall into a pattern of asking the same types of questions for different studies. This might not bias participants, but you can bias yourself if you always investigate the same types of issues. Finally, are you sure you are asking the right questions? Your interview questions might be relevant to you and your project team, but are they the questions that will get at important issues from a user’s perspective?” (Michael Hawley – UXmatters)
