SOME PRACTICAL ADVICE
My previous experimental research has identified more specific behavioural guidance that can improve survival chances in violent attacks, particularly in crowded environments. Using computer modelling and controlled experiments with real crowds, I have identified several strategic areas to improve their survival chance in such events.
First, moving slowly away from danger is not ideal. People need to move away from the source of threat as quickly and safely as possible.
Second, hesitation – whether to gather information, inspect what is happening, or film events – increases the risk of harm.
Third, people need to remain agile in their decision-making and navigation while they are moving and be willing to adjust their movement as situations evolve and information becomes clearer. This means continuously scanning your surroundings and adjusting direction as new information becomes apparent, rather than stopping to reassess.
Finally, when moving with family or friends, travelling in a single-file formation – staying close in a back-to-back snake formation rather than holding hands side by side – benefits everyone by reducing congestion and improving flow.
BE PREPARED
The events in Sydney are horrific and they underline a difficult reality: Preparedness for violent risks in crowded places needs to become more mainstream.
Crowded spaces will always remain vulnerable to deliberate violence, whether driven by terrorist intent or other motivations. Messaging needs to reach more people to be evidence-based, nuanced and widely accessible.
With several major public events and large mass gatherings approaching (including New Year’s Eve), it is more important than ever for people to be aware of these risks and remain vigilant.
