> When I was younger I was pretty painfully shy, so (4) I would not seek feedback, but not out of a lack of humility. To fix such a things in a questionnaire there are 9 questions. Maximum score you could possible get is 9 times 7 = 63, but probably not many people would get so much. Even those who are super humble. > Also (3) I don't get, because while I am extremely motivated by intellectual curiosity, I have maybe zero motivation to "develop my intelligence" like it was some kind of fitness thing. So you do not reflect on your weaknesses in order to develop intelligence? Or you are doing it sometimes, when it is obvious for you that your task needs more intelligence from you? Maybe 3 as an answer would fit? > I don't think that is really related to humility. Good questionnaires are not like a random internet ones. There are special methods allowing to ensure that questionnaire is measuring what we want to measure, not something else. For example, you can measure intellectual humility based on the interviewing a participant, and then ask participant to fill a questionnaire with a 50 questions (or maybe 150, as much as your creativity could devise), that you think might be good. Get 50 participants, or maybe 100. The more is better, but it is a long and difficult task, to interview 100 people, and if you used a several PhD students as interviewers, than you need to control for interviewer also, because different people could get different results even when asking the same questions. So you would need even more participants to get a statistical significance. Number of questions itself also increases the number of data points needed. After you gathered data, you would run it through R to find questions that are the best fit, to reduce questionnaire to bearable size. Probably after it you should test your new questionnaire by the same tactic you invented it. You even might need to do this, if at the first stage you got insufficient number of participants. But now you would need no factor analysis or something like, just a correlation would be enough. Or maybe chi-square. I didn't read an article itself, but it is a published paper in a reviewed journal, so I bet it is done good, not just authors picked 9 questions on a random. Therefore I bet, that if you don't think that it is really related to humility, than you probably should change your mind and think the other way around. If it somehow important for you, I'd suggest to find a full text of paper describing methods used to devise a questionnaire and read them through. Maybe you are right after all. There might be a statistical mistakes, mistakenly used statistical methods for example, or some issues with the data gathering.
