Healthy Scepticism PI Caitjan Gainty considers the definitions of scepticism, and skepticism, and what the ‘healthy sceptic’ of her imagination might look like. She writes in part: “the ‘healthy’ sceptic knows that knowledge-making is a fraught process, that scepticism itself is a marker of good science, that questioning what one knows now is the productive basis required for knowing more, differently or otherwise in the future. We need scepticism, or skepticism, depending on where you live, despite its sometimes antithetical and antagonistic persona, its contrarian tendencies, its occasionally downright unhelpful and dangerous proclivities.”
