Priceonomics

If you wanted to build an algorithm to find the most interesting facts in the world, how would you do it? Since it seems that the modern media industry is built on mining interesting content from the Reddit, we thought that would be a good place to start: we built a web crawler that identifies the most interesting facts unearthed by the Reddit community.

Some of the most interesting facts are brought to light in the subreddit called Today I Learned (TIL). In TIL, users post links to articles or websites that taught them a surprising, specific fact that day. They then write their own title for the post, identifying the salient interesting fact that’s buried in the text. 

For example: a Priceonomics article about the prop money used in movies, called The Business of Fake Money, was posted to TIL with following title:

TIL The fake prop money used in Rush Hour 2 was too accurate. After extras tried to spend what was left lying around after the climax was filmed, the Secret Service raided and seized $100 million in fake bills from the prop maker and accused them of counterfeiting.

As we were reading the articles that got submitted to this subreddit, we noticed something: the same articles kept getting submitted over and over and over. This lead us to believe that these articles were especially interesting, if people were continually surprised by them. 

Not only that, but sometimes someone would submit the Wikipedia page of, say, Albert Einstein and nothing would happen. Other times, it would skyrocket to the front page of Reddit. The difference was the title that the Reddit user used to identity the interesting tidbit was better in the second case.

So our data crawling team built a simple algorithm that would crawl through the Today I Learned subreddit and count how many times a given article was submitted. Then, of all the times it was submitted, the crawler would choose the title that garnered the most upvotes (and therefore identified the most interesting fact in an already exceptionally interesting article).

And so without further ado, we present to you the 17 most interesting facts in the world calculated by the Priceonomics data team and analysis engine, though really all credit should go to the Reddit users (whose titles we copy exactly below) that found the articles and identified what made this interesting.
