Broken windows theory: How to motivate citizens to keep their neighborhood clean

Leave a comment

The broken windows theory, introduced by James Q. Wilson and George L. Kelling in 1982, suggests that visible signs of disorder and misbehavior in an environment encourage further disorder and misbehavior, leading to serious crimes. A classic example is a building with a few broken windows. If left unrepaired, vandals are likely to break more windows, potentially leading to more serious property damage.

During a recent trip to Istanbul, Turkiye, I observed this theory in action through a series of urban landscapes. The following image illustrates the problem. An outside trash and garbage collection area was exposed in a busy commercial district.

In contrast, the following three images demonstrate clever solutions, showcasing how to apply the broken windows theory in urban planning. In the first two images, the trash and garbage collection area was enclosed by an artificial ivy hedge to minimize its visibility from pedestrians. In the last image, the back side of a series of market stalls was enclosed by the decorative wall.

Hiding trash and garbage collection areas may not be a permanent solution. However, doing so will motivate citizens to keep their cities clean. By investing in public spaces, urban planners create environments that naturally deter crime and foster community well-being.

In the mid-1970s The State of New Jersey announced a “Safe and Clean Neighborhoods Program,” designed to improve the quality of community life in twenty-eight cities. As part of that program, the state provided money to help cities take police officers out of their patrol cars and assign them to walking beats. The governor and other state officials were enthusiastic about using foot patrol as a way of cutting crime, but many police chiefs were skeptical. Foot patrol, in their eyes, had been pretty much discredited. It reduced the mobility of the police, who thus had difficulty responding to citizen calls for service, and it weakened headquarters control over patrol officers…

Abstract

Design Fixation refers to the tendency to adhere to pre-existing ideas, which hinders innovative design solutions. This research explores the potential of LLM-powered Creativity Support Tools, the ’Behaviorally Informed Creativity Support Tool (BI-CST),’ to facilitate ideation and combat Design Fixation using ’Behavioral Science Theory.’ BI-CST assists in redefning problems and generating new ideas by presenting experimental fndings from Behavioral Sciences that challenge users’ initial concepts, thus providing a deeper understanding of real human behaviors. We will assign three groups to diferent conditions: one designing without generative AI support, one with open-ended generative AI (e.g., ChatGPT), and one using a model trained in behavioral science. We aim to compare the originality, practicality, and general quality of the designs to assess design fxation. This study addresses design fxation through an interdisciplinary approach combining design and behavioral science, aiming to expand users’ perspectives.

… Behavioral science, a sub field of psychology, aims to understand and predict people’s behaviors through scientific methods ranging from casual observation of daily life to systematic observation to minimize the effects of biases [22, 29]. Its research includes behavioral decision theory, which shows people’s heuristics and biases in judgment [9], and builds nudges that gently alter people’s decision making processes [27]. As this field targets problem-solving by understanding people’s psychology, efforts have been made to apply theories of behavioral science in the HCI field to change users’ behavior [13, 14, 19]. However, there has been limited research on incorporating behavioral science into Creativity Support to aid design processes. We assume that the scientific causal and systematic observational results about human behavior from behavioral science can serve as a ’nudge’ to assist users in gaining more diverse perspectives. (pg. 117)

… We hypothesize that participants using a non-behaviorally informed Creativity Support Tool (CST) in Condition B are likely to reinforce their existing heuristics, which could increase their design fixation. In contrast, participants in Condition C, who will be provided with behaviorally informed guidance, are expected to adopt new heuristics that help reduce their fixation on initial ideas. Specifically, we anticipate that the outputs in Condition A and Condition B will likely exhibit medium to high originality but may have low practicality. Conversely, outputs from Condition C are expected to show medium originality but high practicality, due to the application of evidence-based creative support derived from behavioral science research.

Li, Y., & Joo, J. (2023). The mediating effect of psychological ownership on the relationship between value co-creation and the in-app purchasing intention of mobile games players. Behavioral Sciences, 13 (3), 205.

Abstract

In previous research on in-app purchasing, one of the revenue sources for mobile games focuses on users’ unilateral relationships, such as their achievement, loyalty, and perception. However, little has been discussed about the commercial impact of the bilateral relationship. We extend discussions by examining an unprecedented issue, that is, the role of the bilateral relationships between users and mobile game companies in increasing in-app purchasing intention. We borrow from the business literature and psychology to hypothesize that when mobile game users co-create value with a mobile game company, their psychological ownership of the mobile game increases, which in turn increases their in-app purchasing intentions. To test this hypothesis, we conducted a carefully designed study by recruiting eighty-six Chinese game users. Half of the participants were exposed to an imaginary mobile game whose interface allowed them to co-create value with the mobile game company and the other half were exposed to an identical mobile game whose interface did not. We recruited participants from the two online platforms in which Chinese mobile game players gather—Weibo and WeChat Moment. Using SPSS 26, we conducted an independent samples test to test the effect of value co-creation and employed Hayes Model 4 to test whether psychological ownership mediated the relationship between value co-creation and in-app purchasing intention. We found that (1) when participants were allowed to co-create value, their in-app purchasing intentions increased, and (2) the relationship between value co-creation and in-app purchasing intention was mediated by psychological ownership. Our findings provide fresh insights for mobile game designers and marketers.

How to write and when to send traffic-boosting mobile coupons?

Leave a comment

Chu, W., & Joo, J. (2024). Targeting effectiveness of mobile coupons: from exposure to purchase. Journal of Marketing Analytics, 12, 342-354.

Abstract

This research examines the effectiveness of traffic-boosting mobile coupons through a randomized field experiment of over half a million South Korean consumers. The research question analyzes the effectiveness of the content (six message types) and context (three days out of the week for coupon distribution) of mobile coupons on response-to-coupon, store visits, and purchase amount for a health and beauty retail chain. Big data on individual customers, gathered from a field experiment, was analyzed through bivariate probit, mediation analysis, and tobit regression. The results show that message content affects store visits, which was fully mediated through response-to-coupon. In particular, messages that “made the amount of discount salient” and “formed a personal connection” were more effective than other messages. In terms of context, messages sent during the weekdays were more effective in increasing store visit, than those sent during the weekend.

Abstract

Mental illness has always been an important issue for young adults. Moreover, initiatives resulting from the outbreak of COVID‐19 have had an even greater impact on the mental health of young adults. This study sought to examine the effect of gamification on whether young adults adopt in‐person counseling. One hundred twenty young adults (42 males and 78 females) with an average age of 29 years participated in our experiment. In the experiment, a 2 (Gamification: no vs. yes) × 2 (Vividness: low vs. high) between‐subjects design was employed. In the “yes” gamification condition, participants decided whether or not to read introductory material about in‐person counseling, and also whether or not to adopt in‐person counseling in the future. The results of the study show that: (1) gamification increased adoption, (2) participants’ perception of subjective usability of in‐person counseling mediated the effect of gamification to adoption, and (3) vividness of presentation moderated subjective usability. Our study demonstrated that gamification nudges young adults to adopt in‐person counseling while subjective usability mediates the relationship, and vividness moderates the relationship between gamification and subjective usability. Our findings provide counselors fresh insights into motivating people to access counseling services.

“… gamification has the primary purpose of promoting human motivation and performance in a particular activity. The importance of gamification has been thoroughly discussed theoretically and practically in an increasing number of research studies for health professions education (Van Nuland et al. 2015; Verkuyl et al. 2017;Buttetal. 2018). Ourexperimental study found that gamification does have a positive effect on people adopting in-person counselling” (pg. 1360).

Bundling smart products better by considering consumers’ goals

4 Comments

Abstract

Contemporary electronic manufacturers struggle with how to develop attractive bundles by combining their existing smart products. In the present work, we propose Goal Based Bundling (GBB) by drawing on the academic research of goal systems theory (Kruglanski et al., 2018) and shed light on two previously ignored aspects of bundling strategy: service and glue product. We applied our GBB to a collaborative project with Samsung Electronics, whose goal was to develop new product bundles for kids by combining multiple smart home products. We constructed a framework of Samsung Electronics’ smart products and then visualized it on its sales website. A UI design conveying the value of smart products bundle was developed based on GBB structure. We discuss the process and the result of our project to provide insights into the product managers who combine existing smart products to develop a bundle.

“Although bundling tactics are frequently called upon in business, marketing research on product bundles is surprisingly sparse (Russell et al., 1999). This paper represents an attempt to identify bundling smart products by borrowing the key concepts from the Goal Systems Theory (Kruglanski et al., 2018). We posit that constructing a products bundle following a hierarchical goal structure overcomes the limitation of combining categorically dissimilar products. Moreover, it addresses an important role of service in smart product bundling.” (pg. 2898)

How to attract attention of pedestrians?

Leave a comment

How could we make passing pedestrians stop and look at something? One solution is to apply technology. For instance, tactile pavings or tactile ground surface indicators tell them when to cross roads.

Another solution is to apply design. While I visited Curitiba in Brazil, I was always attracted by fire extinguishers. This is because they are located inside red-yellow squares painted on the ground.

Interestingly, the same rule applies when fire extinguishers are above the ground. Red-yellow squares are painted on the ground even when fire extinguishers are hung on the wall.

Design beats technology in Curitiba.

From beverages to consumer electronics, marketers are using color in innovative ways. Despite this, little academic research has investigated the role that color plays in marketing. This paper examines how color affects consumer perceptions through a series of four studies. The authors provide a framework and empirical evidence that draws on research in aesthetics, color psychology, and associative learning to map hues onto brand personality dimensions (Study 1), as well as examine the roles of saturation and value for amplifying brand personality traits (Study 2). The authors also demonstrate how marketers can strategically use color to alter brand personality and purchase intent (Study 3), and how color influences the likability and familiarity of a brand (Study 4). The results underscore the importance of recognizing the impact of color in forming consumer brand perceptions.

A visual nudge for social distancing inside an elevator

Leave a comment

As Covid-19 spreads widely, people are required to keep distance from others. The Straits Times posted a photo showing that visitors at an Indonesian shopping mall stand on the boxes inside an elevator.

In Seoul, Korea, a clever visual nudge was observed in an elevator. The floor was divided into nine squares, each marked with a pair of painted footprints. This subtle design implied that only nine people should ride the elevator at once.

Not long ago, I believed that floor signage could not influence our behavior, assuming that we naturally internalize rules over time. Back then, a yellow-painted footstep in Singapore or an orange-colored line in Shenzhen seemed unlikely to alter the rules we had already learned. However, my perspective has shifted—I now recognize that floor signage can indeed guide and reshape our behavior.

Governments are increasingly adopting behavioral science techniques for changing individual behavior in pursuit of policy objectives. The types of “nudge” interventions that governments are now adopting alter people’s decisions without coercion or significant changes to economic incentives. We calculated ratios of impact to cost for nudge interventions and for traditional policy tools, such as tax incentives and other financial inducements, and we found that nudge interventions often compare favorably with traditional interventions. We conclude that nudging is a valuable approach that should be used more often in conjunction with traditional policies, but more calculations are needed to determine the relative effectiveness of nudging.

How could we stop cigarette butt litter?

2 Comments

Cigarette butts are the tail ends of the cigarette left over after someone has smoked it. They are under-acknowledged, but widespread, pollutants. At the Quora, someone said the following.

In fact, thanks to the fact that for decades smokers just didn’t care where they threw them, there are very likely cigarette butts in the Amazon rain forest, at the North Pole, and on the fast-disappearing Ross Ice Shelf in Antarctica. Practically the only place they are difficult to find is where they belong – in the trash bin.

To tackle this issue, various efforts have been suggested. According to Tara Rohan, for instance, posters and videos have been provided to educate people about the environmental impacts of cigarette-butt litter. Alternatively, cans have been installed in select neighborhoods. Most of these efforts aim to nudge smokers to throw cigarette butts in trash bins. Recently, I have noticed an interesting approach in London, UK.

At the Portobello Road market in London, bins are installed for those who want to throw gums and cigarette butts. For an unidentified reason, these bins have baby faces. As research suggests that large, round eyes, high eyebrows, and a small chin yielded the perception of a babyish facial appearance.

Since baby face or Kindchenschema (baby schema) is “related to the vulnerable nature of a living entity, it elicits responses from adults that increase the infant’s chance of survival. These include increased attention to and protection of the helpless infant (Brosch, Sandder, and Scherer 2007; Lorenz 1943) and increased carefulness and caretaking behavior (Sherman, Haidt, and Coan 2009). (Nenkov et al. 2014, pg. 326)”

Although adding a human face to the tip jar backfires, having a baby face even contributes to the success of high-ranking Black executives. Designing cigarette bins like cute babies must be effective to collect cigarette butts. I wish similar bins are installed in other markets and cities as well to stop cigarette butt litter.

Livingston, R. W., & Pearce, N. A. (2009). The teddy-bear effect: Does having a baby face benefit black chief executive officers? Psychological science, 20(10), 1229-1236.

Prior research suggests that having a baby face is negatively correlated with success among White males in high positions of leadership. However, we explored the positive role of such “babyfaceness” in the success of high-ranking Black executives. Two studies revealed that Black chief executive officers (CEOs) were significantly more baby-faced than White CEOs. Black CEOs were also judged as being warmer than White CEOs, even though ordinary Blacks were rated categorically as being less warm than ordinary Whites. In addition, baby-faced Black CEOs tended to lead more prestigious corporations and earned higher salaries than mature-faced Black CEOs; these patterns did not emerge for White CEOs. Taken together, these findings suggest that babyfaceness is a disarming mechanism that facilitates the success of Black leaders by attenuating stereotypical perceptions that Blacks are threatening. Theoretical and practical implications for research on race, gender, and leadership are discussed.
