DASHUN WANG: Data can be quite helpful because decades of psychology research or behavioral researchers have shown us there are many human biases when it comes to failure experiences in terms of the way we can recall the failure experiences and to what degree can we learn from it. And that’s where I think I find the results quite intriguing myself, is that namely the eventually failure group, what you see is that every failure along the way, they don’t improve in their efficiencies, that in terms of time between two consecutive attempts that stays constant as you fail over and over.
