The economy that grew 89 percent overnight

From Africa·An enduring case

In 2014 Nigeria rebased its GDP calculation to include sectors like Nollywood and telecoms that the old 1990 framework barely saw, and the economy became Africa's largest overnight, growing on paper by almost ninety percent. Nothing in any market changed that morning except the instrument.

The concepts this raises

Each of these gives a class a different way into the same case.

CertaintyStatus of Knowledge
The degree to which doubt about a claim has been closed off. Certainty is a state of the knower, not of the claim, which is why a claim can be true without anyone being certain of it and why confidence and reliability can come apart badly.
ObjectivityStatus of Knowledge
Independence from the particular standpoint of any individual knower. Objectivity is better understood as something a method or a community achieves through checks on individual bias than as something a single knower can simply decide to have.

Where it sits in the knowledge framework

Methods and tools
The practices, conventions, instruments and forms of reasoning through which knowledge here is actually made, together with the assumptions those methods build in and what they are structurally unable to detect.

Areas of knowledge

Cases that raise a concept this one raises, but in a different area of knowledge or a different part of the world. That contrast is the point: it is what shows a student the concept travels.
