Community involvement in coastal infrastructure adaptation should balance necessary complexity and perceived effort.

Successful adaptation of coastal infrastructure requires public participation, and it is important to elicit accurate feedback from surveys and in-person interactions. But there remains a need for evidence about the efficacy of potential risk communication design metrics. This online experiment (n = 261) sought to understand the necessity of a multifaceted risk perception questionnaire to capture public input. Using six coastal infrastructure examples, risk perceptions were collected using a questionnaire highlighting multiple types of risk (intervention) or not (control). Public evaluations of risk did not differ in most cases. Moreover, the intervention imposed more cognitive strain on participants, which could unintentionally discourage public participation in the climate adaptation process. In this case, the single question provides the same input, with less effort. This finding is a reminder that effective risk communication for managing adaptation processes requires considering both the quality of public input and the effort required to provide it.

Framing to reduce present bias in infrastructure design intentions.

Infrastructure professionals (N = 261) were randomly assigned to either a future or present-framed project description and asked to recommend design attributes for an infrastructure project. The future-framed condition led professionals to propose a significantly longer infrastructure design life, useful life to the community, and acceptable return on financial investment. The findings suggest a straightforward and inexpensive way to lessen present bias in various design contexts.

People systematically overlook subtractive changes.

Improving objects, ideas or situations-whether a designer seeks to advance technology, a writer seeks to strengthen an argument or a manager seeks to encourage desired behaviour-requires a mental search for possible changes1-3. We investigated whether people are as likely to consider changes that subtract components from an object, idea or situation as they are to consider changes that add new components. People typically consider a limited number of promising ideas in order to manage the cognitive burden of searching through all possible ideas, but this can lead them to accept adequate solutions without considering potentially superior alternatives4-10. Here we show that people systematically default to searching for additive transformations, and consequently overlook subtractive transformations. Across eight experiments, participants were less likely to identify advantageous subtractive changes when the task did not (versus did) cue them to consider subtraction, when they had only one opportunity (versus several) to recognize the shortcomings of an additive search strategy or when they were under a higher (versus lower) cognitive load. Defaulting to searches for additive changes may be one reason that people struggle to mitigate overburdened schedules11, institutional red tape12 and damaging effects on the planet13,14.

If humans design the planet: A call for psychological scientists to engage with climate engineering.

As efforts to control climate change gain momentum, so too does the possibility that some global actor(s) will deploy one or more forms of climate engineering. Climate engineering refers to large-scale and deliberate activities intended to change either the carbon-balance or energy-balance of the planet. Climate engineering approaches are untested, involve deep uncertainty, and have far-reaching consequences. Nevertheless, many scientists expect that, relative to conventional mitigation approaches, some climate-engineering approaches will prove less expensive and will require less coordination. They will also have more potential for unilateral deployment. Decisions to pursue climate engineering involve several psychosocial dimensions related to attitude and preference formation, decision making under uncertainty, interpersonal coordination, and health and well-being. Even the prospect of climate engineering could affect norms, goals, and beliefs. The field of psychological science should prepare to help society responsibly consider climate engineering alongside more conventional climate-change responses. This article lays out some initial questions and issues a call to action. It aims to provide common ground for a conversation between climatologists, policymakers, psychological scientists, and members of the public on the important behavioral touchpoints of climate engineering.

Role of community participation for green stormwater infrastructure development.

The primary objective of this research is to understand the role of community participation in green stormwater infrastructure (GSI) development. There is a lack of understanding about the interactions of technical and non-technical factors that promote or hinder GSI implementation and development. This work uses the qualitative case study methodology to fulfil the objective and answer the research questions. The case study is based on the Proctor Creek Watershed, Atlanta Georgia, a rapidly growing urban area located in the southeastern United States. Data sources include participant interviews, documents, and field notes. Findings reveal that community participation in this case is embedded in collaborative partnership efforts. Also, social conditions highly influence the participation processes by dictating the priorities the community develops during participation processes. Factors such as funding and political support, promote green stormwater infrastructure implementation along with community participation. Additionally, community education addresses the challenge of resistance to change, hence community education plays a role in its development and implementation.

Interest in STEM is contagious for students in biology, chemistry, and physics classes.

We report on a study of the effect of peers' interest in high school biology, chemistry, and physics classes on students' STEM (science, technology, engineering, and mathematics)-related career intentions and course achievement. We define an interest quorum as a science class where students perceive a high level of interest for the subject matter from their classmates. We hypothesized that students who experience such an interest quorum are more likely to choose STEM careers. Using data from a national survey study of students' experiences in high school science, we compared the effect of five levels of peer interest reported in biology, chemistry, and physics courses on students' STEM career intentions. The results support our hypothesis, showing a strong, positive effect of an interest quorum even after controlling for differences between students that pose competing hypotheses such as previous STEM career interest, academic achievement, family support for mathematics and science, and gender. Smaller positive effects of interest quorums were observed for course performance in some cases, with no detrimental effects observed across the study. Last, significant effects persisted even after controlling for differences in teaching quality. This work emphasizes the likely importance of interest quorums for creating classroom environments that increase students' intentions toward STEM careers while enhancing or maintaining course performance.
