We found an article online about how some of the technology you use every day isn’t as reliable as you might think. Here are the top six “Gadgets That Lie to You Every Day”.
#1.) The Fuel Gauge on Your Car. You’ve probably noticed that after you fill up at a gas station, the needle goes to “Full” . . . and then stays there for the first 50 miles or so.
That’s because the thing in the tank that measures how much gas you have is just a rubber ball on a stick, like the one in the tank on your toilet.
So when you’re 90% full, it still looks like you’re COMPLETELY full. And when it says you’re on “empty,” you probably still have a gallon of gas left.
#2.) The “Door Close” Button in the Elevator at Work. In most cases, it doesn’t do anything. That’s according to John Menville, who’s been working on elevators for 47 years.
The “door close” buttons in SOME elevators work. But he says it’s usually there just to give us the ILLUSION of control. And it only works for firefighters and paramedics if they use their key.
#3.) Scales. The scale in your bathroom probably isn’t as accurate as you think. But what’s worse is, the one at your DOCTOR’S office might not be accurate either.
Researchers at the University of North Carolina found that 20% of the scales in U.S. hospitals are off.
#4.) The Thermostat in Your Office. It depends on how cheap your company is, but some experts say almost ALL office thermostats do absolutely nothing.
The idea is, if you and your coworkers could constantly mess with it, the heating and power bills would go up. In one industry newsletter poll, 51 out of 70 people who responded said they’d personally installed a fake thermostat.
Luckily, it might not matter. Researchers have found that just turning the dial up on a thermostat makes most people FEEL warmer.
In one study, a bank installed three fake thermostats for three different tellers who’d been complaining about the temperature. And all three of them thought it made a big difference.
#5.) Your Speedometer. How accurate it is depends on a few things, including tire pressure, the weather, how old your alternator is, and how old your tires are.
In theory, your speedometer could be off by up to 10% . . . or seven miles an hour if you’re driving 70. But according to one study, the average is more like ONE percent.
#6.) Your Cell Phone. It lies about two things: Battery life, and signal strength. When it says it’s “100%” charged, it’s actually more like 90 or 95% charged, because being FULLY charged can damage your battery.
But cell phone makers know we wouldn’t be satisfied if it said “95% charged.” So they have it say “100%” instead.
With your signal, the bars don’t tell the whole story. They show how much signal you’re GETTING, but not all of that signal is USABLE.
Two years ago, the magazine “PC World” did an in-depth test of cell phone service in 13 U.S. cities. And in 12 of those cities, they found NO CONNECTION between the number of bars, and the quality of the service.
