Keep in mind that these failed state surveys are very unreliable. The US think-tank that does the survey relies on media articles to achieve their rankings. That to me is a straight red flag. Media articles are always written to achieve certain aim and are very rarely neutral. They might exaggerate a story, might not show part of the story, mighe be unreliable, etc.
For instance, in 2005 and 2006, when Pakistan was a lot more stable than today, they ranked Pakistan around the top. What was more surprising was that countries such as Afghanistan and some African countries far more unstable at the time were ranked lower. They got their ranking through the media article, and for Pakistan the media always concentrates on the negative. There was strong economic growth, poverty reduction, stock growth, etc which went unreported in the media.
Take these surveys with a pinch of salt. They are unreliable, and not neutral. They're meant to achieve an aim or help achieve one. You'll learn this in your basic politics class.
