Introduction
Never has it been so easy to get hold of information, and never has it been so hard to separate the good (reliable) from the bad (false). A single smartphone gives us access to more knowledge than any library in history ever held. The stream of information is overwhelming, and now swimming in it are also more rumours, advertising disguised as news, honest mistakes, plenty of paid opinion and deliberate lies, today increasingly generated by machines as well.
Anyone who wants to think critically therefore cannot avoid one key question:
How do I know whether I can trust what I am reading, seeing or hearing?
That is exactly what this chapter is about.
Media literacy is the ability to find your way around the media world: to find, understand and contextualise content, and to use it responsibly yourself.
Source criticism is the tool for doing so: the practised checking of who says something, where it comes from and how well it is supported by evidence.
The good news: checking sources is no secret science. It consists of a few simple moves that anyone can learn and that are often done in under a minute. Professionals do nothing fundamentally different from practised non-experts; they just do it faster and more consistently.
In this chapter we learn:
- what media literacy actually covers (keyword MIL),
- the SIFT method: four simple moves for quick checking,
- how to tell good sources from bad ones,
- how to search smartly and use Wikipedia properly,
- how social media, algorithms and filter bubbles shape our view,
- what disinformation, fake news and AI fakes are and how to spot them,
- which fact-checking and verification tools are available.
Information is available in abundance.
We simply have to learn to verify it.
We are not betting on distrust of everything here. That would be just as harmful as blind trust. The goal is a practised, calm scepticism: check before you believe, and check before you share.
