The Friendship Paradox

Your friends probably have more friends than you do

Scroll through your friends and they all seem to know more people than you. Is everyone more popular than you?

  • Why your friends seem more popular
  • Who gets counted again and again
  • How friends can warn of a flu outbreak

Why it matters

It changes how you read every comparison you make on social media, and how doctors can spot outbreaks early.
