It is difficult to say which conspiracy theories may have turned out to be correct, as the nature of conspiracy theories is such that they are often based on speculation and lack definitive proof. Additionally, the concept of "consensual" conspiracy theories is not well-defined, as conspiracy theories are often controversial and not widely accepted. With that said, here are a few examples of historical events that were initially perceived as conspiracy theories but were later proven to be true:
The Tuskegee Syphilis Experiment: In the 1940s, the US Public Health Service conducted a study in which they intentionally withheld treatment for syphilis from a group of African American men in order to study the progression of the disease. Initially, this was perceived as a conspiracy theory, but it was later proven to be true.
Operation Northwoods: In the early 1960s, the US military proposed a plan to stage false-flag terrorist attacks on American soil in order to justify a war with Cuba. This plan was never carried out, but it was later revealed to be true through the release of government documents.
MKUltra: In the 1950s and 1960s, the US Central Intelligence Agency (CIA) conducted a series of experiments on human subjects without their consent, in order to study the effects of psychoactive drugs. This was initially perceived as a conspiracy theory, but it was later proven to be true through the release of government documents.
The Gulf of Tonkin Incident: In 1964, the US government claimed that North Vietnamese forces had attacked two American naval vessels in the Gulf of Tonkin, which was used as justification for escalating the Vietnam War. However, it was later revealed that the attacks never actually occurred, and the incident was likely fabricated.
The Iran-Contra Affair: In the 1980s, it was revealed that the US government had secretly sold arms to Iran in order to fund anti-government rebels in Nicaragua, despite a Congressional ban on such actions. This was initially perceived as a conspiracy theory, but it was later proven to be true.
The Pentagon Papers: In 1971, a group of government officials leaked classified documents known as the Pentagon Papers, which revealed that the US government had lied to the public about the progress of the Vietnam War. This was initially perceived as a conspiracy theory, but it was later proven to be true.
The Watergate Scandal: In the 1970s, it was revealed that the administration of President Richard Nixon had engaged in illegal activities, including bugging the offices of political opponents and covering up the break-in at the Democratic National Committee headquarters. This was initially perceived as a conspiracy theory, but it was later proven to be true.
Operation Paperclip: After World War II, the US government recruited German scientists and engineers who had worked for the Nazis, and brought them to the US in order to gain access to their knowledge and expertise. This was initially perceived as a conspiracy theory, but it was later proven to be true.
