When asked how he processed his fieldwork experiences and data, Claude Lévi-Strauss replied that he always took a lot of notes and collected file cards, “a bit of everything, fleeting ideas, summaries of readings, references, quotes.” If he wanted to understand something, he took a stack of cards from the box and laid them out like a game of Solitaire. The random combinations helped him reconstruct his memory and always gave him a new angle on the matter. At first glance, it might appear astonishing to produce knowledge by means of random combinations. But, taking a closer look into the processes of knowledge production, it is not that astounding at all. Tools to collect data, and the ways materials are categorized to produce meaning, are often based on experiments rather than on purely systematic practices.
