To Flush or Not to Flush? Part III

Further In-depth Understanding of the Human Capacity to Act Model

Previously in this three-blog series, we discussed how the Human Capacity to Act (HCA) Framework could be used by researchers to learn about what influences people to dispose of Pharmaceuticals and Personal Care Products (PPCPs) the way that they do. PPCPs get into the environment through flushing and other improper disposal methods and studies have shown that the best way to influence people to change their behavior is by affecting them at the social level. This can be done by educating people about the potential negative influence of their actions and starting a discussion about this within communities.

Figure 4. Human Capacity to Act (HCA) Framework

 

When understanding HCA, the larger the area of the triangle, the more likely a person will change their behavior. With institutional choice having the largest area of the triangle, it shows a greater expected change for behavior change, followed by social proof, and then rational choice at the very top. According to this triangle concept, rational choice has the smallest impact on behavior change, though many agencies and organizations base their outreach and education on rational choice.

Let’s take a look at potential everyday situations:

  • Rational choice: You’re a chain smoker and you see a commercial that says “stop smoking, it’s bad for your health”… does this make you quit smoking cold turkey?
  • Social proof: You move to Corvallis, OR and because most of the people around are OSU Beaver fans, it is easy for you to automatically become one too.
  • Institutional choice: You wear your seatbelt every time you’re in the car because there is a seatbelt law and you may be fined if you don’t wear it.

Now, let’s take a look at a PPCPs example situation:

You look into your medicine cabinet and see a handful of prescription medications that you no longer need or use. What do you do with them? Here’s how the Human Capacity to Act Framework would work in this scenario:

  • Rational choice: You remember seeing a poster at the bus stop that said, “Don’t flush your medication down the drain!” You think that since a poster was made with this message in such strong command words that it must be valid and that you should listen to whomever made that poster. This thought process can be attributed to the assumption that people want to do what is right and that decisions are based off of what people care about. It was mentioned in blog two that typically when someone doesn’t do something, those around them will assume that they simply don’t care about the cause.
  • Social proof: You’re chatting with your neighbor and he tells you about the medication collection boxes where he was able to dispose of a bag of unused medication safely at the law enforcement office in town. Since other people seem to be able to easily do this, it would be achievable for you too. Also, the fact that others are taking the time to protect the environment and waterways by properly dispose of medication, you too can afford to do this.
  • Institutional choice: There is a law against throwing away or flushing your unused medication down the drain and a fee is imposed (hypothetical situation). You avoid flushing simply to avoid paying the fine in this situation.

In the case of institutional choice, you want to avoid being fined for throwing away or flushing your unused medication, so you decided to just keep them in your medicine cabinet longer. In the rational choice situation, you see the poster tell you what not to do, but how much influence does that really have on your decision? Convenience is a huge factor in rational choice – you could think that just flushing a few pills down the drain won’t hurt much. Social proof brings into perspective that when you are unsure of what to do in a situation, you look to the people you trust around you to help make your behavior choice. A person’s experiences and stories can have a great influence on the everyday decisions they make.

 

“The challenge lies in a willingness to do things differently than we have in the past” (Hungerford & Volk, 1990).

 

Routine and convenience have become influencing factors in the decisions we make today, but those are usually driven by individual intentions. With community and trusted networks around, they can become the new source of united intentions. Because responsible behavior is important in the face of PPCPs in the environment, the Human Capacity to Act Model is a new model that displays that education on the community level can lead to PPCP stewardship actions.

 

This blog is the third part of a three-blog series introducing a model and detailing its use through the example of PPCP disposal. As we conclude the series, readers can reflect with a few questions to discuss on your own, with friends, or even in the comments section of this blog: How can you apply the Human Capacity to Action Model in your life? How have you come to the decision to dispose of your unused medications?
