In relationships, it’s easy to judge our partners on quantifiable measures. It’s also easy to produce designs based solely on existing, quantifiable demographics and client requirements. That’s fine if you want a relationship or product that only exists on the surface, but you might miss out on the unique and subtle beauty of the people you design for, and date.
Perhaps online dating would be more successful if it were more focused on the qualitative side of things – the way a person smells or the way you connect in conversation. After all, the quantifiable statement “he’s great on paper” doesn’t have a chance next to the qualifiable “he makes my heart sing.”
