It is  encouraging to read Harvey Hillary's comments about decision-making. We have been able to see clearly how critical decision-making is in sailing, with the extreme speed and risks with the new sailing boats in the America's Cup.

Ultimately every action an athlete takes when competing or training is a decision. From our research and working with athletes, we can see rapid improvements in their decision-making, once we have identified their blind spots and biases.

We have also been working with extreme adventurers, to understand better their decision-making, but also help them improve. In many cases, their decisions are life or death decisions. There is no room for error.
