Be Online Smart: learn more about the role of recommendation algorithms in accessing content in the online world
Many of the online tools we all use – websites, search engines, social media networks – use algorithms to organise the information that they show to us.
An algorithm is a set of instructions or rules that a computer uses to carry out a task, solve a problem or make a decision.
Algorithms are used in many different contexts online, and depending on the task at hand, they can be relatively straightforward – such as putting a list of names in alphabetical order – or highly complex.
Social media and search engines use recommendation algorithms to decide what posts or search results to show each individual user.
Music streaming services use them to predict what music a particular listener might enjoy, based on the other music they are listening to, or on when, where (location and device used) and how (time spent) they are listening. TV and film streaming services use them in a similar way.
It’s important to understand a bit about how algorithms (and those who build them!) shape your experience of the online world, along with your perception of and interaction with the offline world.
Algorithms are used to make decisions about the content you see on different sites, and they have significant influence over the knowledge and information that you are exposed to.
Many social media networks and other websites make money through advertising. Therefore, in order to make more money they want to keep your attention by keeping you on their sites or apps, and keeping you coming back.
Therefore, their algorithms will often aim to show you content that they think you want to see, and content they think you want to share.
Algorithms help to improve your experience of the digital world
Algorithms can ensure that you see relevant and interesting content online. For example, on a social network this might be updates from your closest friends, rather than from those you don’t know very well.
Or on a news aggregator, this could be stories from the news organisations you trust the most, rather than those you don’t often read. And on a music or TV streaming service, this might enable you to discover songs and TV shows that you love but wouldn’t have found otherwise.
But they can also help spread disinformation
…and allow it to very quickly ‘go viral’.
Disinformation often provokes a strong emotional reaction and prompts sharing in a moment of outrage, excitement or disbelief. Algorithms can be exploited to amplify this sort of content, as they will interpret it as content that people want to see.
And keep you in a ‘bubble’
What the algorithms choose for you to see is not the same as what everyone else sees, from Google searches, to social media posts, to recommendations of what to watch next on YouTube. This means that you might not be getting the whole picture online – you could think of this as getting stuck in an information bubble.
STOP
❯ Don’t believe something just because it’s going viral.
THINK
❯ Read the whole story rather than just looking at the headlines on social media.
❯ Remember that algorithms are often programmed to show you content you want to see.
❯ Question the algorithm: think about what is being represented, and what is being left out.
CHECK
❯ Look for multiple sources and learn to find ones you trust.
