Theory

Flow

A state of concentration and enjoyment in which a person becomes so absorbed in what they are doing that they lose track of time, and which appears when challenge and skill are balanced.

In Spanish
Flujo
Origin
Csikszentmihalyi (1975)

What problem it addresses

It explains why a task bores us if it’s too easy, distresses us if it’s too hard and hooks us when it’s just at our level.

Principles

  • Clear goals

    You know at every moment what to do.

  • Immediate feedback

    You see right away whether it’s going well.

  • A matching challenge

    Neither so easy it bores nor so hard it overwhelms.

An example

An illustrative example: a game for learning to code.

Fixed difficulty
The first levels are boring and the last ones impossible. People quit.
Difficulty that keeps pace
Each level raises the challenge a little as the person improves. People keep playing.

Keeping the challenge one step ahead of skill makes the experience engaging.

Why it happens

  1. If the challenge is low, boredom appears.

  2. If it’s too high, anxiety appears.

  3. When they are balanced, attention becomes fully focused.

Applications in design

  • Use it like this

    In games, learning tools or complex products, match difficulty to each person’s progress.

  • Avoid

    Interrupting someone who is focused with notifications or unnecessary steps.

  • Don’t fall for it

    Not every product should captivate: sometimes it’s best for the task to end quickly.

Work > leisure

What the research says

78 adults recorded how they felt for a week. Most moments of flow happened while working, not in free time (Csikszentmihalyi and LeFevre, 1989).

Debated evidence. Even so, they said they were more motivated in their free time. Flow is also hard to measure, and studies use different definitions.
