The substantial and long-sustained decrease in intelligence and social aptitude test scores measured in many aspects of one's life starting roughly the time they become friends with a particular individual. There is no cure for the Williams Effect.
My friends tell me my social sensibilities have decreased upon moving in with my roommate. #TheWilliamsEffect

The Facebook Effect is to know instant in-depth social information about a person. The personal information that can be disclosed includes birthday, hometown, relationship status, siblings, mutual and all other friends, favorite music, movies, and books, home and cell phone numbers, past schools and job places, along with photos and videos.
Would it affect your interest in perusing a person based on if they had a facebook or not?
