  • After conducting the largest online intelligence study on record
  • research team has concluded that the notion of measuring one's intelligence quotient or IQ by a singular, standardized test is highly misleading
  • study, which included more than 100,000 participants
  • ...8 more annotations...
  • Utilizing an online study open to anyone, anywhere in the world, the researchers asked respondents to complete 12 cognitive tests tapping memory, reasoning, attention and planning abilities, as well as a survey about their background and lifestyle habits.
  • expected a few hundred responses, but thousands and thousands of people took part, including people of all ages, cultures and creeds from every corner of the world
  • The results showed that when a wide range of cognitive abilities are explored, the observed variations in performance can only be explained with at least three distinct components: short-term memory, reasoning and a verbal component
  • No one component, or IQ, explained everything
  • scientists used a brain scanning technique known as functional magnetic resonance imaging (fMRI), to show that these differences in cognitive ability map onto distinct circuits in the brain.
  • Intriguingly, people who regularly played computer games did perform significantly better in terms of both reasoning and short-term memory
  • smokers performed poorly on the short-term memory and the verbal factors
  • people who frequently suffer from anxiety performed badly on the short-term memory factor in particular

  • Other things a prospective employer might be able to glean from your Facebook profile is openness to new experiences (vacation pictures from a glacier off New Zealand), emotional stability (are your friends constantly offering you words of comfort?) and agreeableness (are you constantly arguing with "friends?").
  • series of two studies
  • ...16 more annotations...
  • six people with experience in human resources were asked to rate a sample of 500 people in terms of key personality traits using only the sample group's Facebook pages as a guideline.
  • rate members of the sample group on what is known as the "Big Five" personality traits
  • extroversion, conscientiousness, emotional stability, agreeableness and openness to new experiences
  • High scores
  • indication of future good job performance.
  • Members of the sample group were asked to give a self-evaluation and took an IQ test.
  • followed up with the employers of people in the sample group six months after their personality traits were rated, to ask questions about job performance.
  • raters were generally in agreement about the personality traits expressed in the sample group's Facebook page
  • ratings correlated strongly with self-rated personality traits
  • also found that the Facebook ratings were a more accurate way of predicting a person's job performance than an IQ test
  • employers need to tread carefully here
  • Facebook page can provide a lot of information that it would be illegal for an employer to ask of a candidate in a phone interview
  • gender, race, age and whether they have a disability
  • a 2011 study
  • found that 90 percent of recruiters and hiring managers look at an applicant's Facebook page whether they should or not.
  • one study should be used as a reason to start using Facebook in hiring.

  • tested 31 eight- and nine-year-old children who were near the bottom of their class in mathematics but did well enough in other subjects.
