SIFT: Your Method for Deciding What to Believe

In the last chapter you saw where this course is heading and how it feeds your project. Now you meet the engine that drives all of it. When a claim lands in front of you, a headline, a statistic, a confident post, you need something better than a gut reaction to decide whether to trust it. This chapter gives you that: a single, repeatable method called SIFT that you will use, in one form or another, in every chapter that follows.

Learn SIFT, One Move at a Time

Most of us judge information by how it feels. A page looks professional, the tone sounds sure, so we believe it; or it clashes with what we expected, so we dismiss it. The problem is that feeling convinced and being correct are not the same thing. What you need instead is a method you can run on any claim, on any topic, the same way every time.

That method is SIFT, which stands for Stop, Investigate the source, Find better coverage, and Trace claims to the original. SIFT is a four-move approach used by professional fact-checkers.

1. The first move is Stop. Not stop reading, but stop reacting. The moment you feel a strong pull, to believe, to share, or to dismiss, that feeling is your signal to pause and remind yourself you have a method. Strong reactions are exactly when we skip checking.

2. The second move is Investigate the source. Before the page works on you, find out who is behind it and why. A researcher? A company selling something? You are not reading the claim yet, just asking who is talking and what they want. A page selling a supplement is not automatically wrong, but you read it differently once you know that is what it is.

3. The third move is Find better coverage. Instead of reading one page harder, leave it and see what independent sources say about the same claim. If only that one page makes the claim, that already tells you a great deal.

4. The fourth move is Trace claims to the original. So much reaches you secondhand: “a study found,” “experts say.” Tracing means following the claim back to the real study or data. Sometimes the original says something different, or you cannot find it at all, which is just as useful to know.

You will not always use all four. SIFT is a toolkit, not a checklist: you reach for the move that fits the moment.

Know When to Use Each Move

Here is SIFT on a single card. Keep it nearby for the next few chapters. You do not have to act on every move every time; you just need to recognize which one a situation is asking for.

Your Turn!

Below are three short situations. For each one, name the single SIFT move you would make next, and write one sentence saying why. There is often more than one move you could eventually use, so you are choosing the best first move for that moment.

1. You are scrolling at night and a headline about a local council decision makes you instantly angry. Your thumb is already moving toward the share button.

2. You are comparing sleep supplements and land on a confident, polished page from the “National Sleep Wellness Institute”, an organization you have never heard of. It recommends a product that it also happens to sell.

3. A wellness blog states that “every expert now agrees intermittent fasting is dangerous”, but the only supporting link on the page points back to another article on the same blog.

Your deliverable: three lines, one per situation, each naming one SIFT move and giving a one-sentence reason. When you are done, check your answer against the model solution at the end of this chapter.

Let’s Recap!

• SIFT is a four-move method for deciding what to believe: Stop, Investigate the source, Find better coverage, and Trace claims to the original.

• Stop means pausing your reaction, especially when a claim excites or angers you, before you share or dismiss it.

• Investigate the source asks who made the information, and why, before you judge what it says.

• Find better coverage means leaving the page to see what independent sources say about the same claim.

• Trace claims to the original means following a claim back to its first-hand evidence and checking that the evidence really supports it.

You now have the whole method in view. In the next chapter you will slow down and practice the first investigative move in earnest: looking past what a source says to ask who made it, and whether they have a reason to lead you toward one answer.

Model Solution

This is the solution to the “Your Turn!” activity above. Work through the three situations yourself before reading on.

Situation 1: Stop. The flash of anger and the urge to share immediately are the exact trigger for Stop; before anything else, pause and remind yourself you have a method, so you do not pass on something you have not checked.

Situation 2: Investigate the source. Before reading its claims, find out who is behind the “Institute” and why; an organization recommending a product that it also sells has a clear reason to push one answer, and knowing that changes how much weight the page deserves.

Situation 3: Find better coverage. A claim that “every expert agrees” should be easy to confirm elsewhere, so leave the blog and check independent sources; if no one outside this page is saying it, the claim is far weaker than it sounds.
