       | In 1998, the Czech hockey team won the Olympic Games at Nagano
       | and there was a huge crowd waiting for their return on the Old
       | Town Square in Prague.
       | 
       | I went there too, having no experience with crowds of that size.
       | Waves of movement started going through the crowd, sudden bursts
       | of violent pressure that moved you 10 feet or so suddenly. I
       | found it hard to stay upright. Of course, everyone was screaming,
       | so no cries for help would be of any use.
       | 
       | I fled the situation as soon as there was an opening in the
       | crowd. AFAIK no one was hurt that night, but I am still glad I
       | didn't stay. The vicious power of the surges was overwhelming.

         | 
         | 75 minutes? At what point do you say to yourself, "Geez, I
         | don't normally have to stop performing and ask security to help
         | passed out people, maybe I should stop"? I'd ask the same of
         | the venue and promoter, too.
         | 
         | I mean, there were _multiple ambulances in the middle of the
         | crowd_ while he 's performing. Geez.

           | both positions have good supporting evidence and show we need
           | more specificity, and need to talk about a distribution not
           | just an average.
           | 
           | I suspect there are pronounced peaks accross different group
           | sizes where rationality is more emergent, and of course it
           | depends on lot of factors: subject matter, groups

           | I think luskin's citizens assembly research showed that a few

       | 
       | It's stuck with me, and made me more wary and alert when in
       | crowded scenarios to this day. I suppose there's a thought to be
