In my personal experiences I find myself having unexpectedly interesting conversations with a myriad of people, many who may not stereotypically raise my curiosity. I think looks can be deceiving, and this is an attempt to remove that factor to give a chance to anyone who you would find interesting.
In stating this, it's true that you may lose interest in someone after realizing a lack of physical chemistry, but I think the opposite also holds true where you lose interest in someone who's very attractive because of a lack of compatibility. Maybe the best relationships stem from friendships that develop into deeper understanding and compassion.
I think we're heavily focused purely on appearances, and in doing so neglect the other important features that define our uniqueness
