Panic Buying

Shoppers around the world are crazy buying because of fears over the coronavirus(新型冠状病毒), which caused a critical plague in China and even other countries at the beginning of 2020. People in countries such as England, Japan, Singapore and Australia have been emptying supermarket shelves of toilet paper, face masks, hand wash products and dried and canned food. Photos and videos of shoppers in Australia quarreling over the last pack of toilet roll in a supermarket have spread across social media swiftly.

However, governments have advised their citizens that there is no need to “panic buy”. They added that panic buying would only reduce the supply of products needed by patients and medical staff, which could exacerbate the problems the COVID-19 virus is causing. Singapore's prime minister comforted Singaporeans that: “We have enough supplies. There's no need to stock up.” A week after the panic buying fever, things have calmed down and shoppers have gone back to purchasing items in normal quantities.

Psychologists say panic buying is an “unwise” behaviour that is part of a condition called FOMO - the fear of missing out. Dr. Katharina Wittgens said a herd mentality(从众心理) sets in during disasters that causes people to copy the actions of others. People watch the news of items being bought in quantity and immediately rush out to the stores to do the same. She said people were taking on too much the risks of dying from the coronavirus. She said: “Far more people die in car accidents or household accidents per year but we don't panic about these things in the morning before we go to work.”
