In 2021 a book was published called Nudge: The Final Edition. Prior to that, there are several videos and TedTalks on the topic going back over a decade. Prof. Richard Thaler won the Nobel prize in 2017 for the theory. Nudge has become popular in behavioral economics studies. The concept is simple: Most people want to do the right thing, but instinctively take the path of least resistance. A reminder or nudge can put us all on a path towards doing the right thing.
For example, after a sporting event or concert, I have often left garbage behind under the seat (like everyone else). My thinking: 'We all know they have cleaners coming in after, so no guilt'. One day after leaving a game, my friend picked up his beer can and plastic cup. I turned back and did the same. We then waited while many others put their recycling in one bin (the beer can) and the plastic cups in another. Simple, yes, but ultimately, we must be the change we want to see in the world. We can’t expect (or guilt) others to join us, but we can nudge them.
WHAT IS A NUDGE?
When translated, the sign in the above photo in Helsingborg, Sweden reads “A hello can save lives”. Mateja Mihinjac from our SafeGrowth team came across this yellow-painted bench in a downtown park. It was part of Helsingborg's "Friendship Benches Project" and it was an attempt to nudge those feeling alone and alienated seeking conversation to sit at the yellow part of the bench to encourage empathetic passersby to have a friendly conversation.
According to research from the National Center for Suicide Research,“talking is one of the ways to prevent someone from actually attempting suicide”. It is a classic example of "nudge" design to encourage positive behaviour. And Swedish research suggests it is working.
When I hear behavioral economists and behavioral scientists talk about this topic I can’t help my mind wandering over to the CPTED space. Both CPTED and Safegrowth have behavioral elements. Designing a space to nudge others into doing what is best for the environment around them, not what is the most immediate personal win. Spaces to encourage gathering and community building will be activated by someone and followed by others to create a critical mass.

For example, an experiment was described during a TedTalk where a speaker put up signs that said, “Your mother doesn’t work here, clean up your own mess”. The result was a mess left everywhere.
A successful example was putting three garbage receptacles on a beach in a high visibility area with different colours and signs above with examples of what to put in each colour bag. The latter was FAR more successful. A Nudge (subtle) is greater than an order or ultimatum. It gives the individual the agency to make their own decision to do the right thing. Do you ever hear anyone boast that they did the right thing because a sign told them? Rather do you hear “I always do that”? It can become a big part of someone’s personal brand or narrative.

HOW DO YOU NUDGE A SPACE?
Nudging and CPTED take time to change people’s behavior and for most people, it will work. We all need to be patient to see the results over time. In Safegrowth the goal is stated on the website “If Neighborhoods had the skills, tools, and resources to remove, wherever possible, the motives and opportunity for crime.” A lofty goal, but certainly worth the time it takes to understand who and what assets your community has and what assets are needed to accomplish this.
One might think that a survey asking behavioural questions is a good idea, but the problem goes back to the YouTube nudge example above. Putting instructional signs up sounds like a good idea. People would likely answer 'put up a sign' in response to irresponsible behavior. That notion comes from the premise that we all want to do the right thing, but when we see others not do the right thing, we all follow.

Therefore, it is not simply asking the question but instead, it is understanding what behavior needs a nudge. How often have you heard someone explaining bad behaviour by saying, "others do it, so why can’t I?" In criminology, this is known as the techniques of neutralization.
It is not enough to hope for good intentions. In SafeGrowth and in intelligent CPTED, when we look at designing spaces and activating spaces to create community, we always must keep in mind human behavior. For people to comply, they might need a little nudge or two.
