Author here: Walking past a house recently, I watched a dog refuse to leave his porch as the owner explained that the electric fence has been broken for years. It hit me, we're all trapped by fences that stopped working long ago. The mental model that being the first one to reach out to friends keeps us isolated. There are systematic flaws in our modern social protocols that cause smart people to miss social cues, or be afraid of initiating them.

The electric fence has been broken for years.
