Recent years have brought a welcome and needed attention to diversity and inclusion in science communication. This diversity covers language, geography, religion, gender, sexuality — and politics. But with diversity comes complication, where our interest in public communication of science and technology comes in conflict with our identities, our politics, and sometimes even our moral positions. This paper presents a number of examples, highlighting the need for science communicators to be self-reflective about their commitments and how they shape their activities as science communicator practitioners and researchers.

What is science communication for? We argue that science communication can be framed, reimagined and transformed in service of social justice, which is what the papers in this special issue examine. We understand the vocabulary of “social justice” to signal the centring of critical research and practice paradigms, an ethical commitment to righting wrongs, building equity for all human beings and the broader ideal of improving the world [Fraser, 2003; Sen, 2009; Young, 1990]. We argue that bringing critical social justice lenses to science communication can usefully interrogate, rethink and ultimately reshape our field. This special issue examines both critical perspectives on science communication and what equitable transformations might entail.
