The 1990s were a high-water mark for public interest in UFOs and alien abduction. MIT even hosted an academic conference on the abduction phenomenon. But in the first decade of the 21st century, interest in UFOs began to wane. Fewer sightings were reported. Research groups ... disbanded. But now The X-Files is back, and Hillary Clinton has even pledged to disclose what the government knows about aliens if elected president. Meanwhile ... 45 percent of Americans believe extraterrestrials have visited the Earth. Why do reports of UFOs and alien abductions go in and out of fashion? To some extent, this is political. Powerful people and institutions ... influence the level of stigma surrounding these topics. In 2010, sociologists ... found that 69 percent of Americans reported belief in at least one paranormal subject (astrology, ghosts, UFOs, etc.). But [these] findings also suggested that the more status and social connections someone has, the less likely he or she is to report paranormal belief. It may be that people with something to lose have reason not to believe in the paranormal (or at least not to talk about it). So if Hillary Clinton is running for president, why is she talking about UFOs? Part of the answer may be that the Clintons have ties to a network of influential people who have lobbied the government to disclose the truth about UFOs. This includes the late millionaire Laurence Rockefeller ... and John Podesta, the chairman of Clintons campaign.
