An algorithm is a recipe, not magic
An algorithm is a defined sequence of steps for transforming inputs into an output.
The idea
Algorithms reflect the goals, data, and trade-offs chosen by people. Even a highly complex system can optimise the wrong outcome if its objective is poorly defined.
An example
A recommendation system optimised only for watch time may learn to favour sensational content because attention—not quality—is the target.
Put it into practice
When technology produces a surprising result, ask what it was instructed to optimise.
Test yourself: Why can an algorithm optimise an undesirable outcome?
It may be given the wrong objective
Correct. A system can execute its objective well even when that objective is poorly chosen.
