Welcome to episode 4, (series finale if you will) In this installment, we conclude Dr. Pierson's work, "Detectable Signatures of Unidentified Aerospace Phenomena: Building an Intelligence Picture of Capabilities Through Structured Analytic Techniques." As we continue to unpack Dr. Pierson's dissertation, it's clear that his structured analytic techniques and rigorous methodology are setting a new (hopefully consistent) standard for UAP research. By focusing on detectable signatures and building a comprehensive intelligence picture, Dr. Pierson is providing the kind of concrete, data-driven analysis that has long been missing from this field.
