Football has always measured success by what you win, but only in the last twenty years have clubs started to think about how you win. Data has now suffused almost every aspect of how football is played, coached, scouted and consumed. But it’s not the algorithms or new metrics that have made this change, it’s the people behind them. This is the story of modern football’s great data revolution and the group of curious, entrepreneurial personalities who zealously believed in its potential to transform the game. 

When we learn, we change what we believe and how we interact with the world. This changes who we are as people and what we can achieve. Many people grow up being told they are ‘not a maths person’ or perhaps ‘not smart’. They come to believe their potential is limited. Now, however, the latest science has revealed that our identities are constantly in flux; when we learn new things, we can change our identities, increase our potential and broaden our capacity to receive new information. 

Do you know your fractions from your percentages? Your adjacent to your hypotenuse? And who really knows how to do long division, anyway? Puzzled already? Don’t blame you.... But fret not!

For decades, psychologists and economists have studied the science of streaks to determine whether the ‘hot hand’ exists. Is there such a thing as being in the zone? Or is it simply a case of seeing patterns in randomness? Genius scholars and Nobel Prize winners have dedicated years to answering this question. A substantial number of the decisions we make each day are rooted in two opposing beliefs: that if something happened before, it will happen again – or if it happened before, it probably won’t happen again.
