When people are asked whether they would spontaneously assist another person in an emergency, almost everyone will reply positively. However, many refrain and are reluctant to help in real life, especially when they are in the presence of other people during an emergency. This is known as the bystander effect.
In the late 1960s, John M. Darley and Bibb Latané initiated an extensive research to understand the sentiments of bystanders and their decision making process. According to their article, they found that any person who was the sole bystander helped, but only 62% of the participants intervened when they were part of a larger group of five bystanders1.
Three psychological factors were thought to facilitate bystander apathy:
These were shared by Dr Gabriel Ong, Senior Principal Psychologist from the Home Team Behavioural Sciences Centre, Ministry of Home Affairs, during the National Life Saving Day 2023 Symposium organised by Singapore Heart Foundation on 15 Jan 2023.
Based on statistics shared by the Singapore Civil Defence Force (SCDF), only 35% of its myResponder app users responded to an alert and arrived at a fire or cardiac arrest incident in 2019. What is preventing the 65% from responding?
Following the findings from a joint study conducted by the Home Team Behavioural Sciences Centre, Ministry of Home Affairs and SCDF, the six top reasons that inhibited people from responding to emergencies were:

What can we do to reduce the barriers of helping?
With the help of the SCDF operators, responding to an emergency will not seem too intimidating, especially with instructions provided in bitesize.
It is important to not only remove the barriers to help, but also emphasise on the motivators to encourage more people to step out to help during an emergency.
