Mental Shortcuts - Availability Cascade

Availability cascade

Availability cascades are a fascinating phenomenon that can have a significant impact on how we perceive risk and make decisions. They start from a relatively minor event and can snowball into a massive overreaction, leading to widespread panic or government intervention.

Let’s dive deeper into how availability cascades work. They start with a minor event that captures the attention of the media, such as someone finding a razor blade in their Halloween candy. The media reports on the event, and people start to become aware of it. In this case, mothers in the local community become worried and start spreading the word.

As the story gains more attention, it gets picked up by national news outlets, which leads to parents panicking and inspecting their children’s candy. Eventually, the panic spreads, and people stop giving out homemade treats altogether. This is an availability cascade in action.

The reason availability cascades happen is that people start to adopt a belief not because it’s true or prevalent, but because it’s popular. We tend to either ignore minor risks completely or completely over-exaggerate them with nothing in between.

For example, as a parent, you may know the feeling of waiting up at night for your teenage child to come home. You know that there’s a 99 percent chance that everything is fine, but just the thought that something might be wrong can set off a chain reaction of catastrophic thoughts. This is the same principle that drives availability cascades.

The media plays a significant role in starting and sustaining availability cascades. They can take a minor event and inflate it until it becomes a public outcry. It’s essential to be aware of this and to consider whether what you’re seeing or reading is objective journalism or just an availability cascade.

In the end, availability cascades can cause unnecessary panic and overreactions. So, the next time you hear about a minor event blowing up in the news, take a step back and evaluate the situation before jumping to conclusions. By doing so, you can avoid falling prey to availability bias and make more informed decisions based on the facts and reality.
