The Love carnival Tragedy Shows the Psychology of rushes

It was necessity. It was poor planning and far too many people. We were all stuck in a tunnel and no way out. There was a mile long line of people behind us and while the venue filled, they simply closed the exits. We had no place to go and people kept pushing. Once exhaustion set in people could no more stand or keep conscious so they would collapse and people would fall on them and a body pile would assemble, with those at the body never getting back up. It wasn’t fear. People had no choice but to crush each other. They had no place to go but up. Someone who had suffered from the tragedy said.


Bad news from the German city of Duisburg, where a summer parade named the “Love Parade” has been suffered from tragedy. In accordance to the latest news reports, a crowd of people inside a tunnel became overcrowded and panicked, causing a rush which has left at least 15 dead.

There are multiple layers of dark joke in this type of needless death. First, that a meeting named together in the name of peace could result in such a terrible toll; Second, that in the 21st century simple fear by itself is able to cause large wounded. But that’s the paradox of trepidation: a reply that evolved to keep us safe can itself pose a terrible danger, rising up at the most inappropriate times. If anything, the advent of modern technology seems to have left us even more vulnerable to fatal stampedes, as mass moving and instant communication make it easier to bring large crowds together. But this kind of tragedy has a long history.

In lots of the past century’s most deadly fires the most important cause of death was not burning or smoke inhalation but being crushed to death in a panicked stampede. There doesn’t even need to be an actual threat, as long as the crowd believes that there is one. Among the worst mass fatalities during the German bombing campaign against London in World War II was an incident that took place when a crowd of civilians lined up outside the shelter in the Bethnal Green Underground Station.

An air-raid siren had sounded several minutes before, but the crowd didn’t trepidation until a nearby anti-aircraft battery fired a salvo of rockets. A woman carrying an infant stumbled at the top of the steps leading down into the station; the surge of the crowd behind them caused hundreds more to fall. Amid the din of the guns and rockets, no one could hear the screams of the men, women, and children being crushed to death. Within 14 minutes, about 172 people had died. In a twist of grim irony, not a single bomb had fallen.

What causes a crowd of peaceful, if anxious, individuals to suddenly become swept into a blind trepidation? Because I’ve written earlier, the literature on the psychology of trepidation is as yet rather thin, but research workers have recently started to understand the underlying mechanisms.

Just like a forest fire needs a critical density of dry wood in order to arrive at the blowout period, a crowd has to reach a critical density in order to become dangerous. People will continue to grow in size or density until there are about 9 people per square meter — that’s 2,599 people in an area the size of a tennis court. From here, psychologists who have studied mass trepidation distinguish between two major ways that things can go wrong. “Unidirectional stampedes” occur when a crowd reacts to a sudden positive or negative change in force.

A positive change in force might occur when a crowd is stopped by a barricade or a narrowing in a passageway; a negative force is the release of constraining pressure, as for instance might occur when a gate is opened. At Bethnel Green, the falling mother blocked the crowd and created a positive force that stopped the crowd behind her. Based on preliminary accounts from Duisberg, where the fatalities occurred near an entrance gate, a likely dynamic may have been at work.

The second kind of disaster is a “turbulent stampede” that takes place while two crowds merge from different directions or a stationary crowd is induced to panic.

Once panic takes hold, individual free will goes out the window and the mass as a whole becomes subject to a gathered crowd psychology. Not just do people in such situations show a tendency to mimic the behavior of those around them, but the sheer physical force of the crowd can become irresistible, capable of bending sturdy steel stanchions and knocking down brick walls. A horrible aspect of rushes is that these factors can cause victims to overlook completely good exits, as for instance happened in the Station nightclub fire.

If you find yourself are in a rush? Once the rush has begun, you’d better is to stay alert no matter when in a large crowd. Take note of exits and other escape ways, and while the density becomes high enough to seem risky, move away from the middle. Ask yourself: do I truly need to be here? Maybe the greatest irony of stampedes is that, to look back, the attraction which brought the people together seldom seems important enough to merit any deaths at all.

How horrifying. It’s important for us to realize that once the pushing begins, there may be very little that a person in the centre of the crowd can do. Thank God more weren’t hurt or killed.
