When it comes to the end of the world, you probably assume that everyone will act like it's every man for themselves. Without a doubt, movies and TV series have all given mankind a bad name. On the other hand, science has found that human behavior works very differently than these Hollywood motion pictures portray in apocalyptic scenarios.
People are more likely to come together in their time of need than they are to trample each other over. Rather than screaming and running around in circles, we're more likely to help someone in need and to think critically for the mutual benefit of everyone who's stranded in the same situation.
While people are known to panic in the short term, the adrenaline and energy that spikes during the moment of shock do wear off, and once it does, our emotions get the best of us. We've learned from situations like the downing of the twin towers on 9/11 and in natural disasters like hurricanes and tsunamis that people come together to help one another in their time of need much more often than making matters worse for everyone.
Despite the relatively small group of anti-socials who really do behave in an 'every man for themselves' sort of way, science just proves that most of the world isn't like that at all.
