 This reflects the intuition that data, especially when they come in the form of numerical measurements or images such as photographs, somehow mirror the phenomena that they are created to document, thus providing a snapshot of those phenomena that is amenable to study under the controlled conditions of research. It also reflects the idea of data as “raw” products of research, which are as close as it gets to unmediated knowledge of reality. This makes sense of the truth-value sometimes assigned to data as irrefutable sources of evidence—the Popperian idea that if data are found to support a given claim, then that claim is corroborated as true at least as long as no other data are found to disprove it. Data in this view represent an objective foundation for the acquisition of knowledge and this very objectivity—the ability to derive knowledge from human experience while transcending it—is what makes knowledge empirical. This position is well-aligned with the idea that big data is valuable to science because it facilitates the (broadly understood) inductive accumulation of knowledge: gathering data collected via reliable methods produces a mountain of facts ready to be analysed and, the more facts are produced and connected with each other, the more knowledge can be extracted.
