The importance of algorithms in our lives today cannot be overstated. They are used virtually everywhere, from financial institutions to dating sites. But some algorithms shape and control our world more than others — and these ten are the most significant.
Just a quick refresher before we get started. Though there’s no formal definition, computer scientists describe algorithms as a set of rules that define a sequence of operations. They’re a series of instructions that tell a computer how it’s supposed to solve a problem or achieve a certain goal.

The 10 Algorithms That Dominate Our World.
When was the last time you read an online review about a local business or service on a platform like Yelp? Of course you want to make sure the local plumber you hire is honest, or that even if the date is dud, at least the restaurant isn’t lousy. A recent survey found that 76 percent of consumers check online reviews before buying, so a lot can hinge on a good or bad review. Such sites have become so important to local businesses that it’s not uncommon for scheming owners to hire shills to boost themselves or put down their rivals.
To protect users from getting duped by fake reviews Yelp employs an algorithmic review reviewer which constantly scans reviews and relegates suspicious ones to a “filtered reviews” page, effectively de-emphasizing them without deleting them entirely. But of course that algorithm is not perfect, and it sometimes de-emphasizes legitimate reviews and leaves actual fakes intact—oops. Some businesses have complained, alleging that the filter can incorrectly remove all of their most positive reviews, leaving them with a lowly one- or two-stars average.
This is just one example of how algorithms are becoming ever more important in society, for everything from search engine personalization, discrimination, defamation, and censorship online, to how teachers are evaluated, how markets work, how political campaigns are run, and even how something like immigration is policed. Algorithms, driven by vast troves of data, are the new power brokers in society, both in the corporate world as well as in government.

You’re a 16-year-old Muslim kid in America. Say your name is Mohammad Abdullah. Your schoolmates are convinced that you’re a terrorist. They keep typing in Google queries likes “is Mohammad Abdullah a terrorist?” and “Mohammad Abdullah al Qaeda.” Google’s search engine learns. All of a sudden, auto-complete starts suggesting terms like “Al Qaeda” as the next term in relation to your name. You know that colleges are looking up your name and you’re afraid of the impression that they might get based on that auto-complete. You are already getting hostile comments in your hometown, a decidedly anti-Muslim environment. You know that you have nothing to do with Al Qaeda, but Google gives the impression that you do. And people are drawing that conclusion. You write to Google but nothing comes of it. What do you do?
This is guilt through algorithmic association…
