Using Maths To Combat Misinformation
The concept of fake news has become a hot topic in recent years. With the current ease of online interconnectivity, misinformation can proliferate at a rapid rate and pose a large threat to our social integrity. This is particularly true of social media platforms, where misleading content such as articles or videos have the ability to heavily influence public opinion. The statistical analyses of fake news trends helps to play an important role in identifying and combating the spread of misinformation.
Misinformation And Its Impact
Misinformation can be classed as misleading through unintentional inaccuracies, or as disinformation – content that is intentionally designed to deceive. In either case, misinformation can be very damaging. The danger of fake news lies in the rapidity of its spread, which can often become viral due to the highly emotional reactions they elicit or from the echo chambers caused by social media algorithms. Ramifications include political polarisation and social division as well as the erosion of public trust.
A recent example of this can be seen during the COVID-19 pandemic vaccination rollout, where a vast amount of misinformation was shared that lacked scientific evidence, focusing on claims of vaccine negative side effects. This resulted in the hesitancy for vaccination amongst certain demographics, affecting world governments’ efforts to achieve herd immunity and control the health crisis.
Identifying Misinformation
To identify typical patterns of misinformation, mathematical statistics and analysis can be used to establish content credibility and allow for counter measures to be made. By analysing the frequency, sources and spread of information, analysts can use machine learning and data visualisation techniques to see if certain types of content are being shared disproportionality compared to other similar topics.
Techniques such as sentiment analysis involves collecting large amounts of data from shared content by analysing emotional tone through natural language processing. Misinformation typically contains negative sentiments and a large, sudden spike in activity can signal a possible recent spread of misinformation. Network analysis can also help to look at how information is shared between users and identify key influencers and fake news hubs.
Countering Efforts
Once misinformation has been identified, campaigns can be made to raise public awareness of its existence and provide corrected information. Governments can put in place policies to help curb its spread such as the removal of content while enforcing stricter guidelines.
During the 2024 American election between Donald Trump and Kamala Harris, misinformation was spread throughout prominent social media platforms, particularly within the area of immigration. Trump’s claim that many more migrants have crossed the border than actually reported have been circulating online and is particularly prominent when content is shared in other languages, such as Spanish. Content written in Spanish is not as restricted as heavily as English and can have a particularly adverse effect Latino voters. Organisations such as the Digital Democracy Institute of the Americas (DDIA) have aided in tracking misinformation and fact checking content to ensure Latino voters are able to make an informed decision.
Despite such regulators, the challenge of sorting misinformation from truth will continue to be a great one, and arguably is set to become more difficult in the future.
