Manchester City decided to hold a hackathon last weekend to see if somebody could come up with an idea on how to use some of their in-match data.

The winner was an algorithm that could track decision-making during the match.

The essential part of decision-making is to understand the 'cause' and effect'. As I understand it, this will just monitor the 'effect' of the player's decision. However, it will be down to the coaching staff to analyse the 'cause.'

We all have decision-making biases. For instance, hunger will affect your decision-making, as was shown by some research with parole decisions in law court. We also know that stress is the biggest 'cause' for poor decisions. How many deaths on Everest have been caused by poor decision-making?

In football, especially in the second half, you will tend to see more biases appearing often caused by fatigue, pressure (if the team is losing or even if a player is under-pressure from an attacking player). 

However, some of the main 'causes' of poor decision-making are often found off the pitch away from the stadium and training ground. It is at home where some of the fundamental causes of poor decision-making start to appear. Switching from the discipline and structure of the club environment and training, to returning home to boredom, gaming, young children and a very reactive environment profoundly impacts decision-making. 

We see dramatic changes in athlete's performance and decision-making, when we analyse their decision-making blind spots.
