The entire world where we exist is a product of decisions that mankind has taken. From coming up with hospitals, to waging wars, to spreading love, educating people, discoverting new things, implementing policies etc etc. In that case this existence is the manifestation of decisions that have been taken in the minds of billions of people since ages.
The underbelly of decision making is the capacity to draw inference. If drawing inference be the driver of what we do and what we don't, should our entire learning be focussed on being more capable in drawing inference. How to draw inferences without allowing any of our prejudices, biases or notions to colour our view points. To consider the impact of each decision on generations that are going to come to existence.
Its a great skill to have I guess and of supreme importance to society too.
