Ariely decided to conduct a series of experiments to understand cheating. He gave test subjects a math quiz with 20 problems, and promised to give a dollar for each correct answer. The problems weren't hard to solve, but Ariely imposed a five-minute time limit, making it impossible for anyone to complete the test. After five minutes, Ariely collected the test from the volunteers, scored them, and paid them for their correct answers. On average, volunters solved four questions correctly.
Next, he tempted people to cheat. He told a new group of test takers to score their own tests and tell Ariely how many questions they got correct. These volunteers reported, on average, that they solved seven questions. The interesting thing about this, says Ariely, was that the higher average wasn't because a few people cheated a lot; rather, it was because a lot of people cheated a little. Equally interesting was the fact that the amount of cheating didn't change when the reward for a correct question was increased or decreased; nor did it change when the chances of being caught cheating were increased or decreased.
Despite Trump’s denial of climate change the the ghastly attacks on climate science and mitigation in the new proposed budget, the Carbon Bubble — which overprices hydrocarbons and the industries that rely on them, as though we’ll be burning all of them with impunity — is about to pop.
South American polka dot tree frogs are pretty cool, but Julián Faivovich and Carlos Taboada found out they are even cooler when an ultraviolet flashlight is trained on them. They fluoresce. Many animals can see beyond the spectrum visible to humans, and these frogs adapted with this trait. From the abstract: Fluorescence, the absorption of […]
A small (51 men aged 24 +/- 3 years) study published in Neuron tasked experimental subjects with practicing the ancient Greek mnemonic technique of “memory palaces” and then scanned their brains with functional magnetic resonance imaging, comparing the scans to scans from competitive “memory athletes” and also measuring their performance on memorization tasks.
All the filters in the world won’t save your smartphone pics from a shaky hand. To really step up your mobile photography game, you’ll need some kind of mount to hold it steady. You could buy a smartphone attachment for a conventional camera tripod, but who wants to carry that kind of gear everywhere they […]
The forced transition from analog to digital TV signals was probably met with relative indifference from people with Netflix subscriptions and the “I don’t even own a TV” snoots. But anyone living in the vast swaths of the country that don’t have guaranteed high-speed internet, broadcast TV is a perfectly valid (and 100% free) way […]
When Apple revealed the new MacBook in 2016, one of the biggest issues raised with the notebook’s new design (aside from ire over the slew of new adapters you’d inevitably have to buy) was the removal of one of its most beloved proprietary features, the magnetic charging cable. Thankfully, third-party peripheral makers have taken up […]
