Facebook Profiles Reflect Job Performance

Facebook profiles assessed by a three-judge panel accurately reflected employee evaluations from each of the users' employers. Should Facebook be used as a job-screening tool?

What's the Latest Development?


A new scientific study suggests that our Facebook profiles accurately reflect our job performance when it comes to qualities such as dependability and emotional stability. On a three-judge panel consisting of two college students and one professor, the profiles of 56 employed college students were rated according to personality characteristics. The study found that the panel's comments accurately reflected employer assessments of the students in areas like conscientiousness, agreeability and intellectual curiosity.  

What's the Big Idea?

The results of the study suggest that Facebook could be used by employers as an effective tool to screen job applicants. On the other hand, it could open companies to potential law suits over discrimination based on gender, race and religion. Whatever happens, you need not fear those party photos, according to the study. The panel assessed party people as extroverted and friendly, says management professor Don Kluemper and leader of the study. Would you mind if your Facebook profile was seen by your prospective employer?

How to make a black hole

Here's the science of black holes, from supermassive monsters to ones the size of ping-pong balls.

Videos
  • There's more than one way to make a black hole, says NASA's Michelle Thaller. They're not always formed from dead stars. For example, there are teeny tiny black holes all around us, the result of high-energy cosmic rays slamming into our atmosphere with enough force to cram matter together so densely that no light can escape.
  • CERN is trying to create artificial black holes right now, but don't worry, it's not dangerous. Scientists there are attempting to smash two particles together with such intensity that it creates a black hole that would live for just a millionth of a second.
  • Thaller uses a brilliant analogy involving a rubber sheet, a marble, and an elephant to explain why different black holes have varying densities. Watch and learn!
  • Bonus fact: If the Earth became a black hole, it would be crushed to the size of a ping-pong ball.

Project 100,000: The Vietnam War's cruel and deadly experiment

Military recruits are supposed to be assessed to see whether they're fit for service. What happens when they're not?

  • During the Vietnam War, Robert McNamara began a program called Project 100,000.
  • The program brought over 300,000 men to Vietnam who failed to meet minimum criteria for military service, both physically and mentally.
  • Project 100,000 recruits were killed in disproportionate numbers and fared worse after their military service than their civilian peers, making the program one of the biggest—and possibly cruelest—mistakes of the Vietnam War.

China’s artificial sun reaches fusion temperature: 100 million degrees

In a breakthrough for nuclear fusion research, scientists at China's Experimental Advanced Superconducting Tokamak (EAST) reactor have produced temperatures necessary for nuclear fusion on Earth.

Surprising Science
  • The EAST reactor was able to heat hydrogen to temperatures exceeding 100 million degrees Celsius.
  • Nuclear fusion could someday provide the planet with a virtually limitless supply of clean energy.
  • Still, scientists have many other obstacles to pass before fusion technology becomes a viable energy source.
