Chinese love plastic

Chinese government tries hard to reduce plastic waste. Recently, it banned plastic waste import. According to financial times, half of the UK plastic waste need to find alternative places desperately.

In contrast, Chinese people seem to overuse plastics. In Shenzhen, for instance, plates are often wrapped with plastic packages. We should tear it down and throw it away. Sometimes, plastic gloves are provided at the restaurants. We wear the gloves when eating bread.

I suspect Chinese people are addicted to plastics probably because they consider plastics cleaner and safer than water or napkins. If we aim to reduce plastic consumption in China, we should consider the Chinese psychology about plastics seriously.

Do we need floor signage?

We now see a wide variety of floor signage. In Singapore, there is a yellow-painted footstep on the right side of the paved road at the Marina Bay. Since this road is crowded by runners, this signage probably helps them run on the right side of the road.

 

 

In Shenzhen, China, there are orange-colored lines at the subway stations. Since many people are in a hurry, these lines help them not to rush forward when the train is coming, and wait for the next train if they cannot get on.

 

 

Although floor signage is visually salient, I wonder whether this is needed to change our behavior, because we learn rules naturally. We learn how to avoid bumping into other runners when running on a narrow road and we also learn how to navigate a huge crowd to get on a train. Although I am a strong supporter of behavior economics and nudge, I believe some nudges interfere with learning. Not surprisingly, some people argue that behavioral economics are not always as effective as thought (Why nudges hardly help)(The dark side of nudging). We need to study more about which specific nudges are ineffective and how we can modify these nudges.

 

Three escalating numbers are enough to teach moral behavior

In Singapore, we should pay fine when behaving inappropriately in subway: S$500 when eating or drinking, S$1000 when smoking, and S$5000 when using flammable goods. Interestingly, eating durians is also inappropriate but the fine amount of doing so is not clarified. I suspect that Singapore government seems to know intuitively that people follow rules if they see a set of three escalating numbers.

Verbal instructions do not work

People often use verbal signs to give instructions to others. The store owner posts a sign on the window saying, “This is a window, please use the door.” Government officers paint “Look Right” at the pedestrian crossing. However, I have observed numerous store visitors and pedestrians mistakenly push or slide the window and look left before crossing the road. In these cases, a visual signage might work better to attract their attention and guide their behavior.

Traffic light labels help us drink less wine

People often do things while drunk that they regret when they sober up. Opening expensive wines is one of them. In order to solve this problem and, more academically speaking, to overcome the hot-cold empathy gap (proposed by George Loewenstein), I adopted traffic light system.

I place red sticky notes on the definitely expensive wines that I should NOT open while drunk. Yellow sticky notes go for the relatively expensive wines that I stop and, hopefully, think once more while drunk. Daily wines have no sticky notes. Thanks to this simple traffic light system, I regret less in the morning. 🙂

Please help us recycle easily

We want to voluntarily participate in recycling but do so only when it is easy. Here are the two bin boxes available at a university in Seoul. Unfortunately, their colors and their names are not matched: the left one has a blue cover and its green panel says “recycled” whereas the right one has a green cover and a blue panel says “disposable.” The mismatch among name, cover color, and panel color led me to give up choosing one for my empty coffee can. Instead, I threw it away somewhere else. Indeed, behaving in a sustainable way requires huge mental resources. Therefore, things need to be designed carefully in advance.

People say they want sustainable products, but they don’t tend to buy them. Here’s how to change that.

Ground level traffic lights help pedestrians be safe

Tactile paving is a system of textured ground surface indicators. It aims to assist pedestrians who are blind or visually impaired (see Wikipedia) and is also called truncated domes, detectable warnings, Tactile Ground Surface Indicators, or detectable warning surface. In Seoul, Korea, some of the tactile pavings light up at night. Interestingly, its color turns the same color with the traffic light; it turns red when the traffic light is red, and it is green when the traffic light is green.

This lighting system will not only benefit visually impaired pedestrians; it will also enhance the safety of the pedestrians who are distracted by their own tasks (e.g., listening music by earphones or sending text messages by their smart phones)!

Behavior change requires time

Changing behavior is important but challenging. Thus, it attracts huge attention among practitioners as well as researchers. For instance, Charles Duhigg introduced various examples in his book, The Power of Habit: Why We Do What We Do in Life and Business. Professor BJ Fogg at Stanford University proposed a behavior change model at the Persuasive Technology Lab. Designers graduating from the ID, Illinois Institute of Technology summarized the mechanisms and tools on their website, Brains Behavior and Design Group. Most recently, Professor Dilip Soman at University of Toronto teaches Behavioral Economics in Action at his online course.

For me, I have long wished to be ambidextrous. In Asia, however, using left hand to do something (e.g., eating, writing, pointing, etc.) is not viewed appropriate and I had no chance to practice my left hand. Therefore, I have experimented myself since when I left for Canada whether I can practice my left hand so that it performs as well as my right hand does.

Brushing teeth with my left hand was relatively easy at night. However, doing so in the morning was extremely challenging. Although I have brushed teeth with my left hand for the past 10 years, I often find myself brushing teeth with my right hand when I am sleepy or tired, which is often the case in the morning. Indeed, ten-year is not sufficient to master brushing teeth with my left hand probably because I did not stop brushing teeth with my right hand.

I had different experience regarding controlling the computer mouse. Certainly, using mouse with my left hand was very challenging in the first couple of years. However, 3-year of intensive practice paid me off. I could click, drag, and drop icons using my left hand without noticing that I did so with my left hand. This habit relieves the shoulder pain and I can work longer than before. Three-year was sufficient to master using the mouse with my left hand probably because I completely stopped using the mouse with my right hand.

I plan to start sketching/drawing with my left hand this year. Different from brushing teeth or controlling computer mouse, I have not drawn before. In other words, I have no habit to unlearn but need to develop a new habit only. I hope skipping the unlearning stage takes me less time/effort to master sketching with my left hand.
