Questions
What is Algorithms?
An algorithm is a step-by-step procedure for solving a problem, like a recipe for a computer. The word comes from the 9th-century mathematician Al-Khwarizmi. Today algorithms quietly shape our lives, from GPS routes to Instagram feeds that optimise for engagement and decide what we see.
How do you use Algorithms?
Remember that your feeds are curated, so think critically about what you are shown and be intentional with your habits and data. Borrow algorithmic thinking for your own problems too: break complex tasks into clear, repeatable steps, from your morning routine to your work processes.
When does Algorithms matter?
Algorithms is one of the 43 mental models for work, the situations where you ask: How do I get the right things done? Within that, it belongs to “Organising the work”, alongside Boots on the Ground, Cargo Cult and Commandos.
What is an example of Algorithms?
Two stories show it at work: Al-Khwarizmi’s arithmetic (c. 825) and Instagram (2016). Both are told in full in The Mental Models Daily Almanac, which has two stories for each of its 365 models.
Which mental models are related to Algorithms?
Garbage In Garbage Out, Echo Chambers and Goodhart’s Law. Algorithms itself comes from systems.
