Iraq Swears By Dowsing Rod Bomb Detector
jggimi writes "According to the New York Times, more than fifteen hundred remote sensing devices have been sold to Iraq's Ministry of the Interior, at prices ranging from $16,500 to $60,000 each. The devices are used for bomb and weapon detection at checkpoints, and have no battery or other power source. Sounds great, but according to a retired United States Air Force officer, Lt. Col. Hal Bidlack, they work on the same principle as a Ouija board — the power of suggestion. He described the wand as nothing more than an explosives divining rod. Even though the device has been debunked by the US Military, the US Department of Justice, and even Sandia National Laboratories, the Iraqis are thrilled with the devices. 'Whether it's magic or scientific, what I care about is it detects bombs,' said Maj. Gen. Jehad al-Jabiri, head of the Ministry of the Interior's General Directorate for Combating Explosives."
Here in the U.S., a great many of our police departments and even federal agencies spend millions on a technology that is equally ridiculous and unprovable in any sort of peer-reviewed scientific study: Lie detectors. If we can have our lie detectors, then surely the Iraqis are entitled to their bomb sniffing dowsing rods.
The proponents of these devices, when confronted with the undeniable technical worthlessness of them, inevitably retreat to the claim that the actual benefits come from the psychology of having people being "investigated" by the devices believe that they are actually capable of something, and then watching their reactions.
Wow. If you heard it from a co-worker, it must be true!
Anyone who gets the chance to meta mod needs to fix this. Disagreeing with the parent does not make him a troll.
Don't ask me how it works - those witching sticks are just dead wooden sticks in my hands. But, I've seen it work, so I have to believe in it.
No, you don't. As Feynman said, “The first principle is that you must not fool yourself, and you are the easiest person to fool.”
We use the scientific process precisely because we can't just trust ourselves. A few weeks ago, I climbed on a mountain, sat in the grass, and watched the clouds. Suddenly, the clouds started to move backwards and forwards. It's a miracle! I've seen it with my own eyes! Well, no. It's an optical illusion that some people get when staring into a bright light for too long.
Likewise, since all experiments have shown that dowsing rods work exactly as well as random chance, the most likely explanation for your father in law's ability is that he's able to subconsciously deduce where pipes go and where they are broken based on the effects these things have on the environment. That also explains why it doesn't work for you.
