After conducting many user research studies and thinking about the language used in qualitative research, I've realized that I’m not comfortable with the terms "validity" and "reliability." These terms are closely linked to quantitative research and suggest a level of precision that doesn’t fit with qualitative work. I also find the word "truth" troubling, as it often comes with an unquestionable, fixed idea. Instead, I prefer using "credibility" when talking about qualitative research. To me, credibility means the findings are trustworthy and believable, based on the experiences of both participants and researchers. It also recognizes that while one interpretation may reflect the data, it’s only one of many possible explanations.
