Once you understand the dynamics of any group, you can game it.

Marketers know this, as do political campaigners. "Safety in numbers" is overrated for that reason.

If we use the analogy of the flock of sheep and the sheep dog, the dog steers the entire flock, not individual sheep. Why is that? Because the flock group dynamic is set up to follow one another, even when they don't know where they are going.

The dog knows where they are going, and how to get them there.
