First, we will click on the profiles with photos that showcase a person we find sexually attractive. If closeup inspection confirms our original impression we will then scroll over the photo to see if there are any other shots included. If so, we'll then click on the photo reel to lightly scrutinize the album.
If by this point we're satisfied with what we see, or at the very least somewhat interested, we'll then scroll down to read the profile.
Now, how likely we are to want to contact the person will hinge almost entirely on how physically attractive we perceive them to be (photos can lie, photoshop can tell a whole different story). The more attractive the person is to us, the more likely we are to scrounge for commonalities and shared interests, regardless of how completely different a casual outsider - or an asexual version of ourselves - would consider us to be.
"Oh look! This person enjoy generic activities that I may have at some point considering doing at some other stage of my life. How wonderful!"
"I bet they were being sarcastic or fooling around when they said they didn't like to have suitors 20 years their senior message them. How cheeky!"
We may also find ourselves jumping with excitement over the grossly generalized attributes that any human with a pulse finds attractive in others. Unless there actually are people out there seeking evil, humourless robots from outer space who may never come 'down to Earth' for fear of the effects of our planet's crushing gravity.
