  1. IDEA 1 OF 8

    Addiction is not only about substances

    Alter argues that behavioural addictions, to phones, games, shopping or exercise tracking, work much like addictions to substances.

    They involve compulsive behaviour that brings short-term reward but long-term harm to people's lives.

  2. IDEA 2 OF 8

    Tech creators limit their own use

    Alter notes that some leading technology designers kept their own children away from the devices they built.

    He suggests this shows insiders understand how hard these products are to resist, especially for young people.

  3. IDEA 3 OF 8

    Six ingredients make experiences irresistible

    Alter identifies six common ingredients of addictive experiences: compelling goals, irresistible feedback, a sense of progress, rising difficulty, unresolved tension and social connection.

    Many apps and games combine several at once.

  4. IDEA 4 OF 8

    Goals and tracking keep us hooked

    Fitness trackers and step counts set constant targets, Alter explains.

    Reaching one goal simply creates the next, so people can become trapped chasing numbers long after the activity stops being healthy or enjoyable.

  5. IDEA 5 OF 8

    Feedback and progress feel rewarding

    Bright lights, sounds and likes give instant feedback, while levels and badges create a feeling of progress.

    Alter shows how these small rewards, often unpredictable, keep people returning far more than they planned.

  6. IDEA 6 OF 8

    Cliffhangers leave us wanting more

    Unfinished stories and tasks nag at the mind, an effect linked to the Zeigarnik effect.

    Alter explains how series and games use cliffhangers and autoplay to remove natural ending points and keep people watching.

  7. IDEA 7 OF 8

    Stopping cues have disappeared

    In the past, newspapers ended and television shows finished, giving natural stopping points.

    Alter argues that endless feeds and autoplay remove these stopping cues, making it much harder to put the device down.

  8. IDEA 8 OF 8

    Redesign habits and environments

    Alter suggests fighting behavioural addiction by changing surroundings rather than relying on willpower: setting time limits, keeping phones out of reach and replacing hooked behaviours with healthier ones.

    He also urges more responsible product design.
