1. Concept of measurement. The definition of measurement itself is widely misunderstood. If one understands what “measurement” actually means, a lot more things become measurable. 2. Object of measurement. The thing being measured is not well defined. Sloppy and ambiguous language gets in the way of measurement. 3. Methods of measurement. Many procedures of empirical observation are not well known. If people were familiar with some of these basic methods, it would become apparent that many things thought to be immeasurable are not only measurable but may already have been measured.
