Day: September 17, 2018

The news has been inundated recently with reports of Hurricane Florence, which is bashing North and South Carolina. I’ve always wondered why so many people refuse to evacuate when the government tells them to. And why people don’t adequately prepare even when they’re told exactly what to expect.

I read an interesting article on this subject by Robert J. Meyer in the Washington Post on September 12, 2018. He addressed the psychological issues at play when people face an impending natural disaster. The article is called “Why do people stay put during hurricanes? Here’s what psychology says.”

Despite endless warnings and specific information and suggestions about what to do to stay safe, lack of preparedness is responsible for most of the property damage and loss of life in major storms. “…lack of preparedness…is caused by cognitive biases that lead people to underplay warnings and make poor decisions, even when they have the information they need.”

Failure to evacuate resulted in 40 drowning deaths in Hurricane Sandy in 2012. Surveys showed that only 20% of residents had a preparedness plan. And that storm was hyped up the wazoo! It hit my area so I know! We even took our boat out of the water and planted it in the parking lot of the marina to minimize the likelihood of costly damage.

What goes wrong in these situations? Here are some of the cognitive biases that lead us astray in natural disasters.

Excessive optimism is the first cognitive bias that kicks in. People understand that many residents of their area will be affected. They just don’t believe that THEY will be negatively affected. Others rationalize that they survived other storms without preparation so why not this one?

Herd thinking also comes into play. If neighbors aren’t preparing then there’s no social pressure to do more than the basics.

Myopia is another key psychological factor in lack of adequate preparedness. People are short-sighted when it comes to spending money or expending energy on preëmptive actions. They focus on the immediate cost and discomfort, not the more abstract future benefit. So they cheap out on preparedness measures and take the easy way out.

Amnesia also colors people’s anticipation of a natural disaster. People tend to remember the facts of a past storm, but forget how awful it felt to live through it. Memories of emotions fade faster than memories of facts. So reminding people how bad it was the last time seems to have limited effect.

Sound decision-making is impaired by inertia and simplification. People who are unsure what to do, often do nothing. That’s the principle of “inertia at work.” Simplification results in people doing just a few of the many things necessary to be adequately prepared. The thinking goes, “I’ve done three out of twelve things to be safe so I should be okay.” In Hurricane Sandy, 90% of residents bought supplies – but only enough for ONE DAY without power. Woefully inadequate and unrealistic! We were without power for six days, and we were lucky!

The article concludes that the key to better preparedness in the future is accepting the reality of these destructive cognitive biases. We can’t change them so we have to work around them. We have to design preparedness plans that accept them and anticipate them. For example, give people ORDERED lists that say “If you’re only going to do three things, these are the three things you should do.”

Science has increased our ability to predict hurricanes and other natural disasters. But science can’t reduce the human and property damage done by these weather events.

Psychology is the key to helping people make better decisions when they are faced with nature’s destructiveness.
