Facebook algorithms are so powerful they can suggest you friends you've been looking for a long time and who you have not known for a long time. Do not you know how they work? We explain this to you.

Facebook is one of those giants that has grown so exponentially that we do not realize how much it influences our decisions. The false news is a clear example of the power of this network, but today I will stick with another of the keys that made Facebook Facebook: the suggestion of friends .

The same thing happened to all of us: opening the application or the web and finding the message on the wall of " Maybe you know these people ". This is the suggestion of friends, an extremely complex algorithm with which the social network combines contacts with their affinity, kinship or coincidence in time. Sometimes pairings are clear, like our high school classmates, but they usually suggest contacts that we think: "But how do you know this person?" .

Today we will enter dissecting the suggestion of Facebook friends . I have already advanced that, in order to know in depth, the operation of this algorithm is impossible: this knowledge is only in the hands of the engineers. But we can understand his way of acting through the experience at hand and the contrasted facts. So how does Facebook's suggestion work?

Large-scale data crossing in search of correspondence between contacts

The basic operation of the Facebook algorithm is as logical as possible: the social network tries to find patterns of correspondence between contacts . This is why I encourage you to fill out your profile to the max: the more data you have from users, the easier it will be to find matches to match potential friends.

The more complete your profile, the better Facebook contacts will suggest

It stands to reason that if we complete our studies with a specific date and institute, we suggest as friends other contacts who filled this information in an identical way. This is how crossed to study or work colleagues for example. It seems simple but it is not: the amount of data processed by Facebook is so great that making the pairings on such a large scale implies a huge investment in servers and code maintenance. It's called Big Data .

As a social network that is, we rely on it lots of personal information . The studies, the work, where we were born, our age … or the couple, for example. If we tell Facebook that we are married to someone, he will certainly suggest us as friends the other person's relatives. Not in vain, we give you the genealogical links, as we can divide the contacts into friends and relatives.

The social network is configured to capture the maximum number of personal data possible

So far, it's simple, more or less: billions of cross-data on Facebook servers that are and compare to find matches and so assign them as a friend's suggestion . In this way, it is not strange that we see in our walls old friends, companions of the first work that we had or, more controversially, also our first loves.

Bridging the paranormal: when Facebook suggests contacts without a clear relationship

 Facebook and the suggestion of friends. How it works? Why do they appear to you? "Width =" 1000 "height =" 528 "/> </p>
<p> As much as the amount of data handled by Facebook is overwhelming, algorithms and Big Data are able to manage it quickly and efficiently. So if we study in a school, no matter how far from the world, <strong> Facebook will suggest as friends to anyone who fills the same data </strong>. But what if the suggestion has no logical relationship? </p>
<p> Facebook is a sponge when it comes to saving data and information from its users: it stores everything. Our routes, the places from which we upload the photos, look at these photos for details to review, <strong> monitor our connection and publication times </strong> when we pay more attention to the wall, know what we like for reactions to the different publications … Less DNA knows everything about us. </p>

Facebook knows a lot about us that could draw a fairly complete psychological profile

The reason for this is the sale of advertising. Post an ad on Facebook or Instagram gives you all this knowledge: you can target the ad with as specific details as whether users enjoy gifts or are included among an exact population type. So, if you know all this for ads, imagine what you might know to relate to users: The stronger the network of friends becomes, the more service becomes .

 Facebook knows a lot about us that I could draw a fairly complete psychological profile. </p>
<p> There are concrete and proven situations where the suggestion of friends works with contacts that we only register on a personal level. For example: </p>
<ul>
<li> <strong> Email </strong>. The application reads our address book so you can search the database for those contacts that match to show them at the suggestion of friends. </li>
<li> <strong> Telephone </strong>. The same applies to the phone number: how to access the contact list, Facebook is more or less easy to cross the agenda with other users to find matches. </li>
<li> <strong> Correspondence of contacts in other social networks </strong>. Do you have contacts on Instagram that you do not follow on Facebook? He will magically suggest them. And the same goes for Instagram: the network will offer you Facebook friends. </li>
<li> <strong> WhatsApp Chats </strong>. This has happened more than once and shows that there is a close relationship between the two platforms: it is enough to talk in the messaging application with someone you do not have on the calendar so that Facebook can suggest later for you. </li>
<li> <strong> This is a stream of people visiting your profile </strong>. Maybe they are unrelated, but if they visit you on Facebook, they might know you. The suggestion of Facebook friends will be responsible for checking this. </li>
</ul>
<p> In summary: Facebook is that great brother who knows everything and who also watches over us. It's not the only one, of course, but it's the company most interested in getting to know us on a personal level since <strong> your monetization system is based on it </strong>. The more detail you know the better. And remember: Facebook knows absolutely everything. </p>
<p> The suggestion of friends may seem obscure, in fact it is, but it is also useful: I acknowledge that <strong> found me contacts I would otherwise miss </strong>. Is it worth losing some of the privacy just for this? It depends on each one, of course. What is certain is that there is no equal tool to unite the people that fate has decided to separate. Let's keep this. </p>
