“…There are simple ones, such as strontium dating that is reported with high machine precision, implying an age to within a hundred thousand years, and such data can have accuracy (repeatability in reanalysis of adjacent samples), but locally the data fails tests of trueness. For example, results may have shifted away from true age proportional to the sample proximity to a locally contaminating source of 86 Sr (such as andesitic volcanics, see Figure 4 in Luan and Lunt, 2022). We will attempt to show that an evaluation of precision, accuracy and trueness of proxy observations is an important factor in applying Miall and Miall's "hermeneutic circle" of rational investigation.…”

In literature the English playwright Shakespeare proposed that “a rose by any other name would smell as sweet”. Many geologist are also flexible about the names they apply to features, and are tolerant of both over-simplification and even making mistakes in the naming of formations or other features. It appears that precision of a single noun is considered subservient to the essence of the narrative, such as evaluating a hydrocarbon prospect, or giving an interpretation of history. Here it is argued that naming is important because geology is so rich in nouns, and consequently compound errors in the use of multiple, poorly-defined nouns rapidly degrades overall meaning. It is proposed that without names that are both natural and consistently applied, but also continually improved, the scientific framework soon falls apart. By this we mean that the geological understanding of exploration risk, or geological history, rapidly become too easily accommodating of any new data and thus loses all rigour. Good, natural names are the results of tested concepts and are themselves open to further testing. From such testing comes recognition that in nature there are both gradational variation in series as well as discrete categories. A search for good names is inexorably linked to a better understanding of the features concerned.
