Recoding a defining dimension to zero has indeterminate effects on extension.

Evidence

The key point in the context of this chapter is that fixing a secondary-level dimension as 0 has no clear implications for extension: it can go up or down. This is true for necessary and sufficient conditions, as well as the family resemblance concept structures. The general principle is that fixing any given defining dimension as 0 (or 1) has indeterminate effects on the extension of the concept. — Gary Goertz, Social Science Concepts and Measurement, 1489
