Say the early humans not only invented tools but they also evolved swarm intelligence, think of the behavior in shoal of fish and swarms of bees.
Now fast forward to the present day, there is a special organ hidden in the brain which evolved over time to be responsible for intuition and it is particularly sensitive to the infra low brain wave emitted by our brain.
This is quantum mechanical so when people flock together or are within range of each other all affected minds become one collective mind, meaning they temporarily lose individuality.
Technology can be used to broadcast the brain wave frequencies over great distances, coverage is similar to GPS! I'm wondering how would criminal justice works for a hive mind world if any?
