This essay examines the transformation of fundamental assumptions regarding the nature of consciousness and the concept of truth and how it relates to the science of polygraphy.
Abstract
The evolution of polygraphy as a field of scientific inquiry during the modern era is well documented. However, just as polygraphy emerged from and was based upon modern science, the institution of science was itself predicated upon certain philosophical assumptions which became intrinsic to polygraphy as well. Modern era assumptions or beliefs, embodied by polygraphy, were culturally self-evident and remained largely unquestioned and unchallenged until the postmodern era. One of the unquestioned assumptions was the concept of an individuated ego and enduring self-identity at the center of conscious experience. Another related assumption built into the basic structure of polygraph theory is the dualism or separation of observer and observed in conscious experience. Intrinsic to the nature of science is the belief in epistemological objectivity via the separation of observer from observed. This remains intrinsic to polygraph science. The belief that mental states can be measured objectively via methodical recording and analysis of metabolic responses to controlled psychological stimulus is the basis for polygraph theory. However, the meaning of truthfulness and deception in the modern sense has undergone radical transformation during the course of the past century. Basic assumptions have been altered, attenuated, or repudiated in the postmodern setting. The modern era assumptions regarding self-identity, objective inquiry, and truth are being gradually displaced by postmodern assumptions causing polygraph science to encounter difficulties in understanding the postmodern mind. Polygraph theory needs to become more aware of its subjectivity in order that it may become more objective in its perspective. It needs to realize the ultimate elusiveness of truth so that it can come closer to attaining truth. References
