Recently, I wrote an editorial (with my colleague Fabien Medvecky) in JCOM which revisits the idea that science communication should have an ethical component. https://jcom.sissa.it/sites/default/files/documents/JCOM_1604_2017_E.pdf This editorial is, for us, the beginning of talking about a much larger project on which we’re working. But what should our ‘ethics’ conversation look like? Over the years, I’ve heard and seen some suggestions for ethical codes for science communication (some directed toward a journalistic vein, others toward PR, still others that look like academic research codes, and yet others borrowing heavily from communication). We think it’s time to re-open this conversation and are developing some solutions to the ‘multiple codes’ problem. I’d love to talk further with colleagues about this. Our starting proposition is to think about medicine and its principle ‘first, do no harm’. What would a starting proposition for science communication be?
