  1. IDEA 1 OF 8

    Mess can spark brilliance

    Harford argues that people often overvalue tidiness, order and control.

    He shows how disorder, surprise and difficulty can lead to creativity and better results. Harford thinks that too much order can make us rigid and slow, and hold back good ideas.

  2. IDEA 2 OF 8

    A bad piano sparked brilliance

    Harford tells how pianist Keith Jarrett was given a poor, out-of-tune piano for a concert in Cologne.

    Forced to adapt, he gave one of the most famous performances of his career.

  3. IDEA 3 OF 8

    Random prompts help creativity

    Harford describes Brian Eno's Oblique Strategies cards, which gave musicians random instructions to break routines.

    Disruption sparked new ideas. Following a surprising card forced them to try things they would not have chosen, and that often led to fresh sounds.

  4. IDEA 4 OF 8

    Messy desks can work

    Harford argues that messy desks are not always bad, because piles can keep useful items accessible.

    Rigid filing can waste time. Someone with piles knows where things are, while a perfectly tidy system can take a long time to keep up.

  5. IDEA 5 OF 8

    Diverse teams are uncomfortable but effective

    Harford describes research showing that diverse teams feel less comfortable but often perform better.

    Friction can improve thinking. People in diverse groups must explain their views and think harder, which can lead to better decisions.

  6. IDEA 6 OF 8

    Improvisation is valuable

    Harford argues that improvisation helps people respond to changing situations.

    Too much planning can make people rigid. A person who can adjust on the spot handles surprises better than someone who can only follow a fixed script.

  7. IDEA 7 OF 8

    Tidy systems can backfire

    Harford describes how overly tidy plans and targets can fail in complex situations.

    Real life is messy. When people chase a neat target, they may focus on the number rather than the real goal, and lose sight of what matters.

  8. IDEA 8 OF 8

    Automation can reduce skill

    Harford warns that relying on automation can make people less skilled when systems fail.

    A little mess keeps skills sharp. When a person depends on machines for everything, they get little practice and may struggle when the machine fails.
