47 Things People Accidentally Saw That They Wish They Could Erase From Memory

Let’s talk about secrets, which, though common in daily life, are still fascinating. The word “secret” comes from the Latin secretus, which means “set apart” or “hidden.” In English, it first showed up in the late 1300s to describe something that was concealed or kept from public knowledge. So, it’s always been about putting information where others can’t easily find it.

The word “secretary” has an even more interesting background. In the late 1300s, a secretarie was someone trusted with private or confidential matters. By about 1400, the job also included keeping records and handling correspondence, often for important people like kings. It makes sense that secretaries are known for handling sensitive information.

Companies may try for years to control information, but their own paperwork often keeps a record. WorldCom was involved in one of the biggest accounting scandals in U.S. history. The company made its profits look higher by wrongly listing regular operating costs as capital expenses.

This made the company's expenses seem lower and its profits appear much higher than they really were. During the investigation, officials went through the general ledger, accounting records, almost two million pages of documents, about 1.2 million emails, and over 400,000 attachments to piece together what happened.

Enron is another example of how secrets are difficult to hide once they are in a company's records. The SEC charged former executives with schemes to manipulate financial results and with breaking rules about books, records, reporting, and internal controls. Investigators also collected many emails, spreadsheets, reports, correspondence, and other internal documents.

Al Capone was known for his involvement in organized crime, but the case that finally put him behind bars was about taxes. Treasury investigators spent years tracking his income and financial dealings.

In 1931, a federal jury found Capone guilty of tax evasion. He was sentenced to 11 years in prison and still owed back taxes. His criminal empire had survived violence and rival gangs, but he could not escape the evidence on paper.

Perhaps one of humanity's most famous secrets is Area 51. While many people connect it with aliens and flying saucers, the real secret was much more down to earth. The CIA used this remote Nevada site to test the U-2 and A-12 OXCART spy planes and to train pilots in secret.

Because Area 51 was so isolated, it was easier to keep these top-secret programs hidden from the public. Over time, the mystery around the site led to decades of rumors and speculation about what was really going on there.

The Manhattan Project was a highly secret U.S. effort to build an atomic nuke during World War II. Thousands of scientists, engineers, soldiers, and workers contributed to it without necessarily knowing the full purpose of their work. On December 2, 1942, scientists achieved the first controlled, self-sustaining nuclear chain reaction.

Some secrets are more troubling. Project MKUltra, officially approved in 1953, supported research on changing behavior using substances and hypnosis. In 1977, the CIA admitted that some experiments used people who did not know they were part of the studies, and records show secret tests took place in safehouses in New York and San Francisco.

Not all secrets are lighthearted or interesting. Challenging experiences in childhood can continue to matter well into adulthood. Research shows that adverse childhood experiences (ACEs) are linked to adult health and well-being. According to a CDC survey of U.S. adults from 2011 to 2020, 63.9% reported at least one ACE, and 17.3% reported four or more.

For some, these experiences later become part of a broader discussion about mental health. CDC data show that in 2023, 23.9% of U.S. adults received mental health treatment in the past year, up from 19.2% in 2019. Treatment included medication, counseling, or therapy from a mental health professional.

Humanity has never been particularly good at leaving secrets alone. We hide things, uncover things, accidentally see things, and then tell our friends about them. Some secrets change history, others change families, and a few simply make for an unforgettable story. 

There is a strange beauty to secrets: someone always wants to know. Maybe that is what makes secrets so fascinating.
