“The Secret Rules of Living: Algorithms” is an enlightening documentary on BBC Four that explores the mysterious world of algorithms. Presented by mathematician Marcus du Sautoy, the programme investigates how these mathematical formulas dictate our lives, from Google’s search results to traffic light timings. Du Sautoy’s engaging approach makes the topic accessible to all, even those without a mathematical background.

The documentary highlights the role of algorithms in the stock market, where they can predict market movements and execute trades in milliseconds. It also delves into the darker side of algorithms, revealing how they can be manipulated for nefarious purposes, such as the 2010 ‘Flash Crash’ when a rogue algorithm caused a rapid drop in the Dow Jones Industrial Average.

The programme also explores the concept of ‘algorithmic fairness’, questioning whether algorithms can ever truly be impartial. It suggests that algorithms can unintentionally perpetuate biases found in the data they process, leading to discriminatory outcomes. Despite these concerns, the documentary concludes that algorithms are a powerful tool that, when used responsibly, can have a profound impact on society.

Overall, “The Secret Rules of Living: Algorithms” is a fascinating exploration of the unseen mathematical formulas that shape our world. It offers a rare insight into the power and potential pitfalls of algorithms, making it a must-watch for anyone interested in understanding the digital age we live in.
