Title: Taxonomy and Jargon in SETI as an Interdisciplinary Field of Study
Authors: Jason T. Wright
Comments: 3pp, 1 figure, presented as a white paper to the SETI Decoding Alien Intelligence Workshop held at the SETI Institute in Mountain View, CA from 14-16 March 2018. Presented at the workshop by Sofia Sheikh. Workshop white papers available at this https URL
Subjects: Popular Physics (physics.pop-ph)

While SETI is often thought of as a part of radio astronomy with optical SETI, artifact SETI, METI, and other approaches to finding intelligent life considered to be allied fields, SETI is better understood as an interdisciplinary field with many subfields, approaches, and components. In particular, Robert Bradbury has argued for a broad view of SETI between two extremes: "orthodox SETI," or radio communication SETI, and a "Dysonian Approach" that searches for the extreme effects of alien life on its environment. Here, I build on these ideas and attempt to organize the terminology and efforts of SETI within a single framework for SETI as an interdisciplinary and multipronged approach.
