There are also some showing that many people choose unstructured interviews over structured ones because they are overconfident in their ability to assess, and I think one or two that show that unstructured and structured if done properly and together, are better than either method alone. But again, these sorts of studies and metanalyses are very general, so up to you on how seriously to take them. I at the very least found it made me much more cautious of my own assessments in unstructured settings.
It's also true that interviewing isn't just about assessing, it's about giving the candidate information and a good experience. So for instance some studies show that small talk at the beginning of an interview can bias the interviewer. But I still do it because I want interviewee to be as comfortable as possible.
