This dataset contains part of the asnwers to surveys collecting feedback from participants in four participatory workshops within the project SharedDialogues (shareddialogues.org), focussed on exploring the environmnetal crisis of the Mar Menor lagoon (Murcia, Spain). It has been used for generating Figure 2 in the paper entitled 'Tales on co-response-ability in times of environmental polarization' published in the journal Ecology&Society. Participants were asked to rate in a likert scale 1-5 to what extent they personally felt 'safe', 'listened by others', 'understood by others', 'confronted', and to what extent they felt the overall affective tonality of the workshop as 'respectful', 'collaborative', 'tense'. Answers were anonymous and number of participants participating and answering the survey varied from workshop to workshop. This evaluation method has been adapted from: Brugnach, M. de Waard, S.
