I’m lucky enough to live in a beach community and, early each morning, I walk my dog along the beach before work. Although there are trash cans placed every 20 to 30 feet along the beach, there is always lots of litter – especially on Sunday and Monday mornings. On my walks, I watch as the maintenance crew works diligently each day, picking up all the litter from the day before. We’ve gotten to know each other quite well over the years and they tell me that they do this early in the morning to ensure that the beach is nice and clean before beachgoers come out for the day. I feel sorry for them that the task seems never-ending and that their beautiful work is always so unappreciated and gets messed up each day. I have often wondered what could be done to cause people to use the trash cans more and litter less. Who knew that the answer might be for the maintenance crew to not be quite so diligent in their litter collecting!
This week we learned that our individual choices and actions can have a huge impact on the physical environment and that, as individuals, we are often faced with social dilemmas that we have to make important choices about…even when we don’t realize how important our choices are (Gruman, Schneider & Coutts, 2017, p.354). I believe that littering is one of these social dilemmas. The short-term benefit to the litterer is immediate; they no longer have to carry the piece of trash around. The long-term cost to the environment is less tangible to the individual in the moment, less salient, making it relatively easy to choose to litter. However, there are long-term costs: when people leave litter on the beach or in the beach parking lot there is a high likelihood that the litter will end up in the ocean. Here it can affect dolphins, seals, and other marine life through entangling and trapping them or through them ingesting it. Litter in the ocean is also harmful to the environment. For instance, plastic trash is light and so floats on the surface of the ocean stopping the sunlight from getting into the ocean. Plastic also traps the sunlight which makes the surface of the ocean warmer. Both things will affect ocean ecosystems and our climate.
So, the question becomes; how to make non-littering more salient in the moment? Social norms are one of the big drivers of our behavior, telling us which behaviors are/aren’t acceptable (Gruman, Schneider & Coutts, 2017, p.81). As humans we are very motivated to be liked and approved of by others, we also use others’ behaviors to inform us of how we should behave in a situation. Focus Theory of Normative Conduct suggests that, in situations where several social norms are available at the same time, our behavior will most likely be influenced by the focal norm; the one which is most salient (Stok & de Ridder, 2019). It would follow, then, that, if the beach was strewn with litter, individuals would feel it acceptable to join in with this behavior. It would also make sense that, if the beach was kept pristine and did not have a single piece of litter on it, individuals would copy this behavior and not drop litter. Therefore, the work the maintenance crew does on the beach here each morning is valid, useful, and necessary.
Interestingly, in their studies, Reno, Cialdini, and Kallgren (1993) found that whilst a completely clear, litter-free area does lead to less littering, it is not as effective as when a social norm is made focal, drawing people’s attention to a non-littering norm. Their studies suggest that adopting one of the following behaviors would make beachgoers much less likely to litter. The first would be for the maintenance crew to leave a little litter on the beach during their early morning clean-up and only pick up that litter once beachgoers had arrived and could see them doing it. This is an injunctive norm; highlighting to beachgoers that littering is wrong and making this norm very salient in their minds. The second would be to tidy up the beach beautifully during their early morning clean-up and then, once beachgoers had arrived for the day, have someone deliberately drop a piece of trash somewhere prominent. This is a descriptive norm; it would draw attention to the fact that this action was unusual in this tidy environment, reminding people that most people don’t drop litter on the beach.
I found this really interesting and would love to help the maintenance crew out by suggesting they try one of these strategies. However, I can only imagine the looks of horror on their faces at the thought of not doing the best clean-up job possible, or – even worse – deliberately contributing to the littering problem. I’d also be happy to test it myself by going back down to the beach as beachgoers arrive and dropping a piece of trash on the crew’s beautiful sand. I think it would be a good intervention strategy but the personal cost to me – potentially losing my friendship with the crew – is too high. And so we come full circle; my individual choices and actions could potentially have a positive impact on the physical environment and yet every day I choose not to act because my personal reward for not acting is greater than my personal reward for acting.
