Yes

I propose that the observer has two perceptual modes when deciding as to a person's genetic sex status. In the first mode, which I shall call the "naive" mode, the observer does not actively inspect the person for cues as to his/her genetic sex. Thus, features incongruous with the person's gender presentation are likely to be noticed only by accident. In the second mode, which I shall call the "inspection" mode, the observer has a pointed interest in determining whether the person is transgendered and will therefore scrutinize the person for gender incongruencies. In this perceptual mode, the observer's chances of determining the person's genetic sex depend both on the observer's assessment skills and on the subject's prevalence of gender-incongruous cues. While some observers will be better at assessing genetic sex than others, there is an overall probability of being "read" by a member of the population at large, based on the average observer's assessment skills. Let the "naive" mode probability of "passing" (not being read) for a single observer be N, and let the "inspection" mode probability be I.

Hope this helps Marion.
