A teacher can explain bicycle parts, but only you can learn how to ride.
Economic expertise is based in formal and tacit knowledge. Formal knowledge can be written or explained verbally, for example mathematical properties of the Metropolis-Hastings algorithm. But tacit knowledge - practical know-how - comes from doing.
Research is a process for creating new knowledge that relies on both formal and tacit knowledge. Researchers communicate this new knowledge through argument, which is composed of the following parts:
1. a main point, which is also known as a recommendation / claim / conclusion / thesis / assertion
2. evidence, such as historical facts, data visualizations, econometric results, citations of existing research findings, etc.
3. assumptions/theory (also known as 'reasons') that link evidence to the main point.
4. argument structure: the overall inferential architecture—how the evidence and assumptions fit together to support and imply the main point.
