At its most basic, an algorithm is a procedure to solve a problem. A computer program can be a procedure to solve a problem expressed in a computer language.
On many social media and digital commerce sites (Facebook, Twitter, Instagram, Netflix, Amazon, Google, Microsoft, and on and on), algorithms control how users experience the sites–what they see, the options they are offered, who they communicate with, etc. Algorithms can be developed to maximize revenue and/or spread misinformation or disinformation.
Corporations, advocacy groups, governments, criminal organizations, and others use algorithms in an attempt to control and influence the actions of individual users. It may be simply to entice people to make more purchases or spend more time on a site (thereby generating more advertising revenue). Or, the goal may be darker, to use individuals to influence the outcome of larger events–such as elections.
See: The Facebook whistleblower says its algorithms are dangerous. Here’s why. (Karen Hao, MIT Technology Review, October 5, 2021)
Even academic sites and databases use algorithms. While the motivation and consequences may be less driven by profit-seeking or disinformation, they can still be impacted by corporate rivalries.
While algorithms can have positive impacts, what we see most vividly today are their negative impacts.
Part of evaluating the content and source of information is to understand the context and motivations behind why information was produced and, as a result, how it is being displayed (words, graphics, colors, formatting, layout, options, etc.).
Take charge of the information in your life, especially when it is important to you.
