Get the Most Out of This Course
Welcome. Before you learn anything about evidence, it helps to know what this course is really about, how it is built, and how to get the most out of the hours ahead. This short chapter sets you up so that every later step feels like a natural next move rather than a surprise.
Why a Good Question Does Half the Work
Most reasoning goes wrong long before anyone looks at the evidence. It goes wrong at the question. Ask something too broad (“Is social media bad?”) and no amount of research can settle it. Ask something loaded (“Why is this product obviously the best?”) and you have hidden the answer inside the question. Ask something you cannot actually measure, and you will argue forever.
This course is built on a simple idea: a well-framed question does half the work. When your question is specific, answerable by evidence, and scoped to a real decision, the rest of the process, gathering and combining evidence, becomes far easier and far more honest. That is why you will spend the first part of the course learning to build the question before you ever try to answer it.

Discover the Course Plan
The course teaches one transferable method in two parts, and the two parts do different jobs.
Part 1, Frame and Scope an Inquiry Question, helps you turn a broad concern into a single, specific, researchable question with clear limits and a standard for a good answer.
Part 2, Synthesize Evidence Across Sources, helps you combine several partial, sometimes conflicting pieces of evidence into one integrated answer you can defend, with honest confidence.
Between framing and synthesizing sits a third skill, judging how trustworthy each individual source is. This course does not re-teach that skill; the companion course Develop Your Critical Thinking covers it well. You do not need it to follow this course, but the two fit together naturally.
How to Study This Course
A few habits will make the hours you invest pay off.
Read the worked examples slowly. Each part contains one fully worked case that takes a topic all the way through the method; that is where the method becomes concrete.
Do the “Your Turn!” checks before reading the model solution. These checks are for your own learning only. They are not graded and carry no stakes, so treat a wrong first attempt as useful information, not failure.
Practice on your own topics. The method is transferable on purpose. Once you have seen it work on the course examples, try it on a real question you actually care about.
You will notice the examples come from everyday life, community decisions, consumer choices, health questions, rather than any single job or industry. That is deliberate: the point is a way of thinking you can carry into any subject.
Now that you know how the course works, let’s start building the questions themselves, beginning with what actually makes a question answerable by evidence.
