4. Context of research Crowd behaviour theories have developed over time Crowd behaviour theories have developed over time 19 th Century- Le Bon irrationalist approach 19 th Century- Le Bon irrationalist approach 1960s - 70s more rationalist approach 1960s - 70s more rationalist approach From 1980s to present- crowd behaviour increasingly seen as governed by social norms- beyond rational or irrational as this is a matter of interpretation -The Social Identity Model From 1980s to present- crowd behaviour increasingly seen as governed by social norms- beyond rational or irrational as this is a matter of interpretation -The Social Identity Model

5. The ‘Panic’ model Part of the irrationalist tradition in crowd psychology Part of the irrationalist tradition in crowd psychology Reproduces dominant image: Reproduces dominant image: a)Threat causes emotion to overwhelm reason a)Threat causes emotion to overwhelm reason b) Collective identity breaks down b) Collective identity breaks down c) Selfish behaviours- pushing trampling etc c) Selfish behaviours- pushing trampling etc d) Contagion-these behaviours spread easily to crowd as a whole d) Contagion-these behaviours spread easily to crowd as a whole

6. Scope of research project 3 year project funded by ESRC since April 2004 to see if existing psychological models of crowd behaviour can be applied to emergencies 3 year project funded by ESRC since April 2004 to see if existing psychological models of crowd behaviour can be applied to emergencies Taking a critical look at the ‘panic model’ Taking a critical look at the ‘panic model’ 3 different areas of research; interviews, room evacuations, and VR simulations 3 different areas of research; interviews, room evacuations, and VR simulations

9. 7 th July terrorist attacks Individual fear and distress, but no mass panic Individual fear and distress, but no mass panic Evacuations characterised by orderly, calm behaviour Evacuations characterised by orderly, calm behaviour Many reports of altruism, co-operation, and collective spirit of Londoners/ UK as a whole Many reports of altruism, co-operation, and collective spirit of Londoners/ UK as a whole

10. Why no Mass Panic? 1) British Bulldog spirit meant we were used to it or even expecting it ? 1) British Bulldog spirit meant we were used to it or even expecting it ? 2) Information withheld? 2) Information withheld? 3) Mass Panic is extremely rare anyway? Only when chance to behave co-operatively has gone 3) Mass Panic is extremely rare anyway? Only when chance to behave co-operatively has gone

11. The myth of Panic Many accounts of ‘panic’ Many accounts of ‘panic’ But what actually is panic, and what is logical flight behaviour? But what actually is panic, and what is logical flight behaviour? Need to look at what people actually do, and decide if it is indeed ‘panic’ Need to look at what people actually do, and decide if it is indeed ‘panic’ More than just semantics, as it could affect emergency evacuation planning More than just semantics, as it could affect emergency evacuation planning

13. Panic? 1)’There was no real panic - just an overwhelming sense to get out of the station quickly’ 1)’There was no real panic - just an overwhelming sense to get out of the station quickly’ 2) ‘almost straight away our packed carriage started to fill with smoke, and people panicked immediately. Thankfully there were some level- headed people on the carriage who managed to calm everyone down’ 2) ‘almost straight away our packed carriage started to fill with smoke, and people panicked immediately. Thankfully there were some level- headed people on the carriage who managed to calm everyone down’

14. Unity ‘I felt there was a real sense of unity. We were all trying our best to find a way out of there and reassure each other’. ‘I felt there was a real sense of unity. We were all trying our best to find a way out of there and reassure each other’. ‘One of the things which struck me about this experience is that one minute you are standing around strangers and the next minute they become the closest and most important people in your life. That feeling was quite extraordinary’ ‘One of the things which struck me about this experience is that one minute you are standing around strangers and the next minute they become the closest and most important people in your life. That feeling was quite extraordinary’

15. Co-operative behaviour 1)‘Many people kept calm and tried to help one another to see if anyone was injured’ 1)‘Many people kept calm and tried to help one another to see if anyone was injured’ 2)‘I was very aware of people helping each other out and I was being helped myself’ 2)‘I was very aware of people helping each other out and I was being helped myself’ 3) ‘Passengers with medical experience were found, I found a tool box and we smashed a window, allowing the medical guys to enter the other train’ 3) ‘Passengers with medical experience were found, I found a tool box and we smashed a window, allowing the medical guys to enter the other train’

16. Orderly evacuation? ‘Everyone was pretty calm and no-one made a rush for the doors in a panicked fashion’ ‘Everyone was pretty calm and no-one made a rush for the doors in a panicked fashion’ ‘About 20 minutes later the message came through that those who could walk should move to the front of the train and disembark and walk down the track. [] after a short distance we were stopped and told that a person had been blown out of the train against the tunnel wall and could not be moved as he was critical’ ‘About 20 minutes later the message came through that those who could walk should move to the front of the train and disembark and walk down the track.

21. Stockwell shooting 22/7/05 ‘Lots of people at the other end started shouting "Get off! Get off!" and running down the platform away from the train. I heard 5 gun shots, although did not see anything as I was running away from the train trying to find an exit. We all followed each other and reached a dead end on the Victoria line platform, everyone was very frightened and didn't know where to go’ ‘Lots of people at the other end started shouting "Get off!

25. Possible applications of my work 1) More information rather than less 1) More information rather than less Very little evidence supports idea that people will panic if they know severity of the situation Very little evidence supports idea that people will panic if they know severity of the situation If information is given in clear ways that people can safely act upon to escape threat, they usually do If information is given in clear ways that people can safely act upon to escape threat, they usually do Consequently, deliberately withholding info could cause problems in any future emergencies, as people may not trust accuracy of messages Consequently, deliberately withholding info could cause problems in any future emergencies, as people may not trust accuracy of messages

26. Possible applications of my work 2) How this information is relayed and by whom affects whether it is believed and acted upon 2) How this information is relayed and by whom affects whether it is believed and acted upon Information needs to be clear and unambiguous, and come from believable source that crowd identifies with Information needs to be clear and unambiguous, and come from believable source that crowd identifies with This could depend on type of crowd; e.g. commuters, football fans This could depend on type of crowd; e.g. commuters, football fans

27. Possible applications of my work 3) Appealing to the crowds’ collective identity/ common humanity 3) Appealing to the crowds’ collective identity/ common humanity Having a common fate can encourage co- operative behaviour- ‘we’re all in this together’ Sir Ian Blair-‘communities defeat terrorism’ Having out-groups can strengthen in-group identity, but is a double-edged sword
