I guess experience counts quite a lot. If you practice typing soon you can see how people fit in without really thinking about model a or dichotomies.... Just the recurring patterns in how they look and behave and what you've seen before. To start with its hard because you don't even have 16 examples from real life to compare with. Maybe you can take a different angle by thinking about who you strongly relate to .... Celebrities friends or role models. If you could be someone else who would it be you could make a list....
