Five behavioural economics theories to nudge employees to better health

People are people – that means they make irrational decisions all the time

People, despite their best intentions, often don’t make rational decisions when it comes to their health. Just because they know what they should be doing — say, taking a daily blood pressure medication or getting in 30 minutes of exercise most days of the week — doesn’t mean they’re actually doing it.

The consequences of these decisions can impact both their health and employers’ bottom lines. 

As employers look to control the costs of extended health care and keep employees healthy, a relatively new area of interest has emerged — behavioural economics.

This area of study blends the insights of psychology and economics to provide a framework for employers to understand employees’ decisions and encourage healthy behaviours.

Benefit plan professionals have a heightened interest in encouraging workers to make rational decisions.

But behavioural economics has proven that irrational thought prevails, and employers must adjust communications and group benefits plan design accordingly.

Here are five behavioural economics theories that can help an organization nudge employees to better health.

Make the most of inertia

Despite having good intentions, people have a strong tendency to not take action. Think of all the subscription services popping up lately — from clothing and snacks to books and pet supplies.

These companies bank on the fact that most subscribers will not take the time or make the effort to stop the automatic shipments.

It’s easier for individuals to continue receiving their monthly boxes than go through the hassle of cancelling the service.

With health, as with physics, Isaac Newton’s “law” applies — a body at rest stays at rest.

Here are a few ways to help employees overcome their tendency for inertia to improve their well-being:

• Encourage employees to enroll in automatic prescription drug refill programs through their pharmacy. For individuals with chronic medical conditions, automatic drug refills can help them more easily adhere to their doctor’s medical orders — and perhaps avoid costly and more serious medical conditions down the road.

• For employees struggling to find the time to exercise, suggest they set their alarm to go off 30 minutes early each morning, giving them time to exercise before they come to work. Of course, they may hit snooze three times, but they may actually get up and exercise. And, there’s a good chance inertia will keep them from resetting that alarm.

• While giving tips to employees who want to eat more healthfully, suggest they subscribe to a service that automatically sends healthy groceries or already-prepared meals to them. If the box arrives on their doorstep, the food is paid for and then it’s in their refrigerator, so they’re likely to eat it — and not stop the shipments.

Show what others are doing right via social norms

When making choices, people tend to follow the crowd. Why? Researchers think humans may be wired that way or they demonstrate herding behaviour.

In following others, people often believe this will prevent them from making a mistake.

If Sarah from accounting tells her friend Amy in sales how helpful the employee assistance program (EAP) is, Amy is much more likely to consider the EAP a helpful resource than if she gets a lengthy email from HR touting all its benefits.

So, establish social norms by pointing out the positive actions employees are already taking, and encourage more employees to follow their lead.

Messages like “50 per cent of your co-workers got their flu shot” or “80 per cent of ABC employees participated in a wellness event last year” can help establish positive workplace social norms and encourage specific employee behaviour.

Couple that with the message “Were you one of them? Don’t be left out!” Generally, individuals don’t want to feel like they’re missing out on something if everyone else in their workplace is participating.

Use loss aversion to prompt employees to act

The loss aversion theory states that the potential for loss has a much stronger pull on decisions than the potential for gain. Accordingly, people are highly motivated not to lose.

Keep this theory in mind when crafting your communications — find a way to focus on what will be lost by not taking action, instead of what will be gained by taking the action. One great motivator for people is money.

Many employers offer incentives for employees to participate in wellness programs. These incentives can involve cash, gift cards, discounts, raffle prizes, even extra paid time off.

If you’re encouraging employees to participate, try using a message like “Don’t leave money behind, participate in the wellness program to collect your gift card.” 

Share stories more than statistics

Let’s say there’s a new wellness initiative that provides nutrition counselling to employees.

All the communications about the new program feature alarming statistics about how few fruits and vegetables Canadians eat or the negative ways obesity can impact an individual’s health.

People have seen all these statistics before — they’re unlikely to remember them or to act because of them.

Instead, bring in a co-worker who has participated in the nutrition counselling program. Have him share his story: He’s been overweight since childhood and on countless diets throughout the years. He’s struggled to make healthy eating decisions.

Now, after completing the counselling program, he feels confident in his food choices. He’s been able to stop taking medications. He’s lost weight, and gained a better outlook of the future.

This story — and approach — will resonate with employees. They can relate to their co-worker’s story, even if it isn’t their own personal story.

Personal stories have far more impact than statistics.

Use the anchoring effect to help establish healthy behaviours

The anchoring effect says that an individual uses an initial piece of information in order to make subsequent judgments.

For example, while shopping, if a person sees a pair of shoes that costs $800 and another pair that costs $150, she might have thought the $150 shoes were expensive if she had seen them alone — but now they seem like a real bargain.

By using the anchoring effect theory, employers can encourage employees to choose healthier food options at work. When deciding what or how much to eat, people tend to look at what they are being served as a starting point.

They unconsciously use that as their anchor or example of a healthy or unhealthy choice, or a “normal” serving size.

For employers that provide on-site cafeterias or snacks, consider offering smaller portion sizes, such as half-sandwiches and smaller beverage containers.

Make healthier items the default options throughout the menu, such as fruit instead of potato chips. Use smaller plates and bowls for self-serve to encourage appropriate portion sizes.

Rethink benefits and wellness initiatives

For years, it was assumed people made rational decisions.

They recognized when important decisions needed their attention, and then spent time and energy researching their options and calculating the pros and cons.

After making these careful decisions, they would have the commitment and discipline to follow through appropriately.

But researchers are now discovering this is not the case. All humans consistently make irrational decisions.

As employers, it’s important to remember this fact — and keep it front-of-mind when designing wellness programs and group benefits for employees.

Prepared meals not the answer - Kristaps Kuplais05/8/2019 10:13:25 AMSubscribing to already prepared meals is the worst advice ever.... How is that healthy? It is the same as eating out... If you want to be healthy and love your body, the only way to keep that way is to cook at home as much as you can... look at baby boomers' health compared to the millennials.. who is healthier?
