The process of research may involve multiple stakeholders, including actors of the civil society. Integrating heterogenous contributors to the ESR ecology requires a shift in epistemological and social frameworks to make scientific contributions more distributed, collaborative and truly accessible while preserving the quality and standards of scientific knowledge. This 1.1 version is a first attempt to capitalize on the hacker/maker experience to write guidelines for successful interactions with research institutions which may be useful to a broader spectrum of actors of the civil society. It is embedded in a dynamics which started in 2018. On July 2018, ESOF (Euroscience Open Forum), took place in Toulouse. ESOF is a big interdisciplinary science meeting organized every two years in Europe. It is dedicated to scientific research and innovation and gathers scientists, policymakers, business people, students, journalists. More than plenary conferences, several sessions are organized in parallel according to different tracks (scientific, careers, business programmes). We proposed a session entitled “Soft hacking Science: Learning from success and failure at the intersection between research and hacker / maker culture”, together with other organizations: HackYourPhD, Epidemium, La Paillasse, DIY Science Podcast, Institut Pasteur, Vulca European Program, RFFLabs. At the end of the session, we decided to summarize our exchange in the form of guidelines to foster interactions between hacker/maker culture and research institutions. This document is named « Guidelines to foster fruitful interactions between institutions and ccommunities » and referred below to the document as « V1.0 » On july 2019, a thematic school (Ecole thématique « LA RECHERCHE ACTION PARTICIPATIVE AU CŒUR DES SCIENCES EN SOCIÉTÉ » held by GDR PARCS (www.gdrparcs.org ) took place in Mèze, 1-5 juillet 2019) . During this training program, a focus group had been organised by two members of the Laboratoire interdisciplinaire Sciences innovation sociétés (LISIS) and of La Paillasse to gather more insight into interactions of scientists and actors of the civil society during participatory action research programs. The V1.0 of the guidelines were provided to the participants. The notes from this 3 hours workshop were collected and used to produce the 1.1 version of this document which has the ambition to broaden the scope of the 1.0 version to a more diverse spectrum of civil society actors. We do not intend to speak for all civil society or research institutions involved in citizen sciences but we feel compelled to share a vision of interactions between sciences and society founded on our diverse experiences. We have been implementing open scientific practices, promoting collaboration between structures and disciplines in our everyday work and in our organizations and institutions. As a consequence of the enlargement of the scope of this V1.1 document, the concepts have to be considered widely. For example, the word “communities” stands for “hacker communities and any other civil society actors such as NGOs and communities” and that of “institutions” for “public organizations and private industrial firms”. In addition, the types of interactions have to be considered by large, and include diverse processes and objectives such as hacking and citizen sciences. Finally, citizen sciences has no consensual definition. We will return here the one proposed by to Haklay (2013) when he refers to “ read with respect to the level of cognitive engagement and type of contribution...” Hecker “... from problem choice to the interpretation of results...” and Houllier[1] (2016, our translation) who characterized them by the active and deliberate participation of "non-scientific-professional actors". This loose definition reflects a great diversity in the forms of organization and the actors involved, the objectives and epistemic practices, the processes and categories of knowledge produced. We hope that these guidelines will foster and be useful to collaborations between actors from any worlds interested in fruitful interactions over knowledge production and circulation.
