Indeed that's a tricky one. My guess is that the average person lacks sufficient self-awareness to be able to answer a question such as that, especially if there are strong insecurities or other fears. At the same time, I believe that many people could attain a better skill at answering such questions if they practised meditation more regularly. It seems that the nervous system pretty reliably adjusts its sensitivities to the recent norms, so maybe the answer to this predicament involves not only (a) asking participants such questions, but also (b) establishing for each person the current systemic bias. Similar to pain-threshold testing, perhaps the person could be exposed to social scenarios, such as in videos, while being monitored with an EEG or related device. The pre-screening done on the experiment participants in the 2001 film "The Experiment" could be seen as similar since it tests emotional reactions. Even persons from different worldly cultures and religions would presumably have different biases, so finding this bias for each individual would probably be very important if accurate analysis were sought. To give an analogy, asking people questions on feelings is like asking a multi-meter for a reading. The problem is that each person has a large set of calibration knobs, so the real-world measurements can not be known without first checking the knobs.
