Overview
A new free online book by a Swedish engineer argues that the evidence surrounding unidentified flying objects has become difficult to dismiss, while examining the psychological and institutional factors that may contribute to an alleged UAP cover-up. Titled 99% – Sure About UFOs: The Psychology Behind UFOs, UAP and the Cover-Up, the publication presents the author’s personal shift from skepticism to near-certainty.
The book’s website describes the author as an engineer, DJ and former skeptic from Gothenburg who has lived in Berlin. According to the author, applying the same analytical standards used in his professional work led him to a conclusion that “became hard to avoid: 99%.” That figure is presented as a personal assessment rather than a scientific measurement or the result of a formal investigation.
From Skepticism to Conviction
The publication is framed as a guide to evaluating extraordinary claims in what the author calls a “fragmented information world.” Its central narrative follows his movement from viewing UFOs as science fiction to believing that at least some reports deserve serious consideration.
Rather than focusing exclusively on alleged sightings, the book emphasizes how people decide what to believe. It examines the roles of evidence, uncertainty, stigma and institutional trust, arguing that public understanding of UAP is shaped not only by available data but also by the ways governments, media organizations and individuals respond to the subject.
The author’s description does not establish that extraterrestrial craft—or any specific unexplained technology—has been identified. Instead, it reflects one individual’s interpretation of reports and public events. The website provides the book free of charge through an online document, allowing readers to review the arguments directly.
The Alleged Cover-Up and Its Psychology
A major theme is the possibility that secrecy and disinformation have influenced the UAP narrative. The book lists “cover-up & psyop” among its principal subjects and explores how official silence, social stigma and competing explanations may affect public perception.
The term “cover-up” remains contested. While governments have historically classified military technologies and restricted information about unidentified aerial incidents, such practices do not by themselves demonstrate a coordinated effort to conceal nonhuman activity. The book’s argument is therefore best understood as an interpretation of institutional behavior and information management, rather than a confirmed finding.
Its psychology section asks why people reject or accept unusual claims and how evidence should be weighed when records are incomplete or contradictory. That focus reflects a broader debate in UAP reporting: witnesses may be sincere, yet sincere testimony can still be affected by memory, expectation, limited observation conditions or misidentification.
Sweden, Europe and the Disclosure Debate
The publication also places the subject in a European context, with particular attention to Sweden’s reported 1946 “ghost rockets” and the region’s continuing relative silence compared with the United States. It references a global disclosure movement involving countries including the U.S., Brazil and Japan.
The website defines UAP as the term currently used by the U.S. Department of Defense, noting that it is broader than “UFO” and carries less cultural stigma. It also describes “disclosure” as the gradual public release or acknowledgment of government information, pointing to congressional hearings in the United States since 2023. Those hearings have increased public scrutiny, but they have not provided universally accepted proof of extraterrestrial origins.
Access and Context
The book is available to read online at no cost through links published on the project’s website and associated UAP platforms. The material is presented as a personal and analytical account, not as an official government report or peer-reviewed scientific study. Readers will need to distinguish documented events from the author’s conclusions, particularly when assessing claims about a coordinated cover-up.
No independent expert commentary or additional source material was provided alongside the promotion. As a result, the book’s central “99%” conclusion remains the author’s stated position. Its significance lies primarily in illustrating how a technically trained former skeptic interprets the expanding UAP debate—and why questions of evidence, psychology and institutional trust continue to shape public discussion.
