Schüll's Addiction by Design and the slot machine analogy

What happened

Anthropologist Natasha Dow Schüll published Addiction by Design: Machine Gambling in Las Vegas with Princeton University Press in 2012. The publisher's description says it draws on fifteen years of fieldwork in Las Vegas. The American Ethnological Society's page lists it as a 2013 prize winner and cites it as Princeton 2012.

The psychological idea

The publisher's description says the book explores the machine zone, a trancelike state in which players lose track of their surroundings and keep playing for as long as possible. It covers the design of machines, casino spaces and player tracking. It also asks whether addiction to gambling machines stems from the consumer, the product or the interplay between the two.

In practice

The description says electronic slot machines have replaced table games as casinos' main source of revenue. A separate popular use compares social feeds to slot machines. Law professor Eric Posner's 2017 blog post likens Twitter to a slot machine through a variable schedule of rewards, which he attributes to Skinner. He cites no empirical studies and writes in hedged terms such as 'suspect' and 'sense'.

Why it mattered

The book offers a field-based account of how a product can be shaped around continuous play. Commentators have used the slot machine image for feeds, which is why this record keeps the ethnography apart from the analogy.

• Treating social feeds as slot machines is an interpretation by commentators; the opened sources do not show platforms copied casino design.
