What is "Epistemics?" Tradition has it that the term was invented by Christopher Longuet-Higgins. If you consult the 1977 Fontana Dictionary of Modern Thought, you will find on page 209 the following definition:

epistemics. Word coined at Edinburgh University in 1969 with the foundation of the School of Epistemics. It signifies the scientific study of knowledge, as opposed to the philosophical theory of knowledge, which is known as epistemology. A more extended definition of epistemics is 'the construction of formal models of the processes - perceptual, intellectual, and linguistic - by which knowledge and understanding are achieved and communicated'.
