On my way to the conference last week I spent some time on the same large conveyance as three other people traveling to the same destination. They were traveling together, but I had never met them, nor they I. We were all aware that we were being picked up together at the end of the trip, however.
When we met up at the place we were supposed to be picked up, I introduced myself to the three of them and we started chatting. During the conversation one of the three said, "We had you picked out on the trip." When I inquired as to what had given me away, she suggested the following items (which may differ slightly from those I actually own) that I provide for you to paste onto your own scientist paper doll.
At first I found this odd, until we got to the meeting and I was struck by the phenotype of the people (who are not in my direct field) there and how clearly I matched. It was nearly comical. Maybe I'm meant to change fields and never got the memo.
In any case, it got me wondering if there are other "uniforms" in different fields and how they might differ from the model I suggest here.
