There is no general public! Each group that you engage with has a shared knowledge base. Effective communication relies on using the knowledge context of that group to plant the new ideas, approaches, or knowledge. Science communication is, therefore, more than just presenting the facts. It is about presenting the facts in a way that is approachable for your target audience. How you deliver your message is tailored every time the audience shifts.
