Sorry, I use it on a baseball forum a lot. SSS=small sample size.
That's cool!
I'd contend, though, that if someone's the most famous person on Earth, it should be
very difficult to find someone who's not heard of them. And if we've already found eight within such a tiny - if admittedly unrepresentative - sample size, what are the odds that we've stumbled onto a profoundly unique corner of the internet?
It's like searching for traces of life on Mars. If one planet in an unimaginably vast universe has life on it, we have no idea whether it's the only one or not. It might be a freak - a tiny, cosmic accident, an almost impossible thing that just happened to occur somewhere. If we find the planet next door has life, too, then there's no way we're alone.
What this thread proves - or very heavily implies, despite its small sample size - is that you don't have to go far to find someone who doesn't know who Lionel Messi is.
Let's say not Messi but it has to be a sport player and here is the reason why. If people have access to internet and TV then they are probably exposed to sports at some point in their daily life. For people that don't, sports is normally the way they use to kill boredom and that usually makes it become an interest to those people which will probably make them more exposed to sports. And aside from that, there are lots of countries that are only known because of their sport players which makes their people feel proud that they have someone that can put their name in the map and that makes them be more interested in that person and the sport he plays. Even in Europe where there's tons of 1st world countries they adore sport players.
So, a kid from let's say Ivory Coast who worships Didier Drogba because he's the best player they've ever had probably has heard about Beckham or Messi while it's not that likely that he knows who Obama or the Queen of England are.
Thing is - and this is a sincere question, because I don't know how it applies to the broader globe - when you say "people," do you mean "men?" Because men's football is very freely accessible. Women's football, not so much.
