This was one of my grandfather's favorite tools, he'd take my brothers out on field trips that could last days, and him and my brothers would make me sit in silence the entire time.

Days of being unable to talk while they all interacted with each other.

I encountered this again as an adult... I was unknowingly hired to be a scab in a union dispute between a city and their union workforce for some legal job. The union's tactic was 100% silence against the contract workers.

I only stayed there for 3 weeks, but even then I noticed the new contractors were already starting to lose their minds. I saw one guy who made it 6 months in that environment and he had a total mental breakdown.

It's attacking the way human beings work on a biological level. Sinister, effective, yet invisible.

Pretty fucked up shit.
