Background Citizen science is increasingly recognized as a valuable scientific approach across disciplines, contexts, and research areas. However, its rapid expansion and diverse methodologies make it challenging to establish a single definition or universal criteria for what constitutes citizen science. Building on our previously published work that detailed findings from a vignette study used to identify the ECSA Characteristics, this paper specifically focuses on the descriptive results from that study and examines the Characteristics in relation to the ECSA 10 Principles of Citizen Science. Methods We developed the ECSA Characteristics through a vignette study, a survey method that captures diverse perspectives on complex topics. We then reviewed the ECSA 10 Principles of Citizen Science, a broad framework for best practices in citizen science, to identify its gaps and limitations, showing how the ECSA Characteristics can help address them. Results The results highlight the disciplinary distinctions as well as ambiguities surrounding various citizen science practices. In this context, it is beneficial to adopt an inclusive approach and language that allows the audience to define its own criteria depending on its needs, intended use and specific circumstances. Conclusions The ECSA Characteristics were developed in a spirit of openness; identifying areas with diverse and even conflicting views was central to this practice. We recommend their use as a whole set and contend that no one area or characteristic is more important than the other. They should be considered as a toolkit with examples that can guide efforts towards defining citizen science for a specific context and purpose. They are built on the ECSA 10 Principles, addressing some of their gaps and limitations, while at the same time acknowledging the need to update and improve the 10 Principles based on developments in the field.

Background Citizen science is increasingly recognized as a valuable scientific approach across disciplines, contexts, and research areas. However, its rapid expansion and diverse methodologies make it challenging to establish a single definition or universal criteria for what constitutes citizen science. This paper introduces the ECSA Characteristics of Citizen Science, offering a nuanced exploration of the field to support stakeholders, including policymakers and research funders, in understanding and applying citizen science effectively. Methods We developed the ECSA Characteristics through a vignette study, a survey method that captures diverse perspectives on complex topics. We then reviewed the ECSA 10 Principles of Citizen Science, a broad framework for best practices in citizen science, to identify its gaps and limitations, showing how the ECSA Characteristics can help address them. Results The results highlight the disciplinary distinctions as well as ambiguities surrounding various citizen science practices. Two challenges exist when defining citizen science. A very strict definition could exclude valuable practices, hindering innovation and discouraging public participation. Conversely, a loose definition might make it difficult for specific audiences to apply it effectively in their own contexts. Therefore, it is beneficial to adopt an inclusive approach and language that allows the audience to define its own criteria depending on its needs, intended use and specific circumstances. Conclusions: The ECSA Characteristics were developed in a spirit of openness; identifying areas with diverse and even conflicting views was central to this practice.

This exploratory paper proposes the use of pragmatist philosophy as a methodological bridge between design and the social sciences. It develops John Dewey’s ecological notion of the ‘situation’ into two novel methods for sensing and mapping situations. The first method, called ‘sensing situations’, aims to help designers become more aware of the diverse elements that make up a situation and develop a deeper understanding of it through embodied experience. The second method, called ‘mapping situations’, is based on Adele Clarke's concept of ‘situational mapping’ and is intended to identify key actors, power dynamics, and areas for design intervention within a given situation. The potential of these methods is to use Dewey’s situation as a shared unit of analysis that allows designers and social scientists to work together and address problems in new and innovative ways that go beyond the traditional scope of their respective fields.

This article analyzes how artists and scientists use emotion as a methodological tool to study participants and cocreate projects. It uses a science and technology studies approach to identify a typology of five emotion assemblages and the material, social, and cultural components that make them operate. These assemblages include or eliminate cultural and environmental context, the role of participants, and artist/researcher reflexivity The paper argues that there is an imperative for artists, designers, and researchers to make deliberate choices as to who or what to include and exclude when working with emotion.

Citizen science has expanded rapidly over the past decades. Yet, defining citizen science and its boundaries remained a challenge, and this is reflected in the literature—for example in the proliferation of typologies and definitions. There is a need for identifying areas of agreement and disagreement within the citizen science practitioners community on what should be considered as citizen science activity. This paper describes the development and results of a survey that examined this issue, through the use of vignettes—short case descriptions that describe an activity, while asking the respondents to rate the activity on a scale from ‘not citizen science’ (0%) to ‘citizen science’ (100%). The survey included 50 vignettes, of which five were developed as clear cases of not-citizen science activities, five as widely accepted citizen science activities and the others addressing 10 factors and 61 sub-factors that can lead to controversy about an activity. The survey has attracted 333 respondents, who provided over 5100 ratings. The analysis demonstrates the plurality of understanding of what citizen science is and calls for an open understanding of what activities are included in the field.

Citizen science is a transdisciplinary approach that responds to the current science policy agenda: in terms of supporting open science, and by using a range of science communication instruments. In particular, it opens up scientific research processes by involving citizens at different phases; this also creates a range of opportunities for science communication to happen This article explores methodological and practical characteristics of citizen science as a form of science communication by examining three case studies that took different approaches to citizens' participation in science. Through these, it becomes clear that communication in citizen science is ‘÷always’ science communication and an essential part of “doing science”.
