Do YOU have what it takes? Scientists reveal personality checklist for people who could colonize Mars

Bad news for those who struggle with anxiety, get too competitive, or simply choke under pressure: new research suggests that you may have to stay at home on Earth while other, more laid back and'agreeable' types colonize Mars. The new study, which is still undergoing peer review, ran computer simulations tracking the progress of human settlements on the Red Planet through their first 28 years of virtual operation. 'Agreeable personality types were assessed to be the most enduring for the long term,' the researchers found, across all four of the personality types used in their simulations, 'whereas neurotics showed least adaptation capacity.' The researchers also discovered that the minimum number of settlers needed to successfully operate a human colony on Mars was much lower than previously expected: just 22 people. 'Contrary to other literature,' they wrote of their simulated Martian colonies, 'the minimum number of people with all personality types that can lead to a sustainable settlement is in the tens and not hundreds.'
