That is so cool! I wonder what cues we can pick up from the discreet sniff. That would be a sweet experiment to find out what your scent conveys, and how it comes across to people. Humans don't think about scent-- we talk about seeing and hearing, but we hardly ever talk about smell (unless it's really strong/offensive), and yet it still influences us. Realtors, for example, bake cookies in a house they want to sell, because it makes things smell like home. Grocery stores have bakeries for the same reason, and have noted increased sales because of them.
I wear scented lotion on my wrists and hands-- would that make the other person like me based on the nice floral scent, or distrust me based on the lack of natural chemical cues? And how much does the scent influence people-- is it subconsciously more or less important than the firmness of the handshake, directness of eye contact, or the sincerity of the smile when you greet someone?
I don't know how you would test this, but I hope someone does, because I want to learn more.
