Is the Bermuda Triangle Actually More Dangerous?

Last updated 2026-08-17

Fifty-some ships and planes, one stretch of ocean between Florida, Bermuda, and Puerto Rico, and a name that's been shorthand for "unexplained disaster" since the 1960s. The debunking is almost as famous as the myth itself by now — dozens of pages exist purely to say "it's not really more dangerous." That made it worth checking not whether the debunking is right, but whether the specific evidence it leans on is as solid as its confidence suggests.

The claim

Ships and aircraft disappear inside the Bermuda Triangle at a rate meaningfully higher than in other heavily-trafficked parts of the ocean, and maritime and insurance authorities treat the area as measurably more hazardous than they treat comparable waters.

Source trail

The name and the mystery both trace to a specific chain: a 1964 Argosy magazine article by Vincent Gaddis coined "The Deadly Bermuda Triangle," and Charles Berlitz's 1974 book The Bermuda Triangle turned it into a bestseller. The debunking side has its own specific origin: in the early 1970s, reference librarian Larry Kusche re-investigated the same widely-cited cases and, according to multiple secondhand accounts of his research, contacted the U.S. Coast Guard and Lloyd's of London directly while writing his 1975 book The Bermuda Triangle Mystery — Solved. The claim that "Lloyd's doesn't charge higher insurance rates for the area" — repeated in nearly every debunking page we found, including Wikipedia's own — appears to originate there: a fifty-year-old piece of research, filtered through decades of secondary retelling, not a document Lloyd's currently publishes or that anyone can check firsthand today.

Verdict

Every named authority we could directly check — NOAA, and through NOAA's own page, the Coast Guard and Navy, plus WWF's 2013 global shipping-accident study — agrees the Bermuda Triangle isn't statistically more dangerous than other well-traveled waters. On that conclusion, there's no real disagreement to report. What doesn't hold up as well is the single most-cited piece of supporting evidence: that Lloyd's of London itself has confirmed this. That claim, repeated almost everywhere including Wikipedia, traces back through a science-agency page we couldn't load to a fifty-year-old book's secondhand account of a conversation — not to anything Lloyd's has published that we, or apparently anyone else recently, can actually go and read.

Similar shape to our briefs on the most expensive object ever built and how much the internet weighs: the headline number or claim is repeated everywhere, but the citation trail behind it runs out sooner than its ubiquity suggests. More research briefs.
