Now we are talking

I may have some news for you. Like gravity, global warming and gun crime, this is not a matter of opinion. It is an observable fact. Unlike individuals, masses are predictable. That is the difference between psychology and sociology. We are not talking about how people should behave. We are talking about how they do.

It's like "wish lines", the paths trodden diagonally through the grass where two paved footpaths cross at right angles. People should walk on the pavement, but they don't. You can manage one individual or even a small group and direct them around, but try managing a crowd of a few hundred. You have only two options: install a fence to force them around (the "closed" solution) or pave the diagonal path across (the "open" solution). Everything else ends up in a mess.

Absolutely correct. Now here is the crux. You can set some expectations from parties involving one, two, or even a hundred individuals if you are skillful enough. But you cannot set expectations involving masses. You need to change your own behaviour.
