Believe it or not, you make decisions without realising them, the fundamentals of snap decisions which take place in milliseconds influence our life greatly. By trusting your instincts or 'listening to your heart' you can eventually make decisions that prove to be better than well analysed and considered decisions, although it does not work like this all the time. In the field, military commanders makes crucial decisions in the matter of seconds. In 2002, the US military conducted a massive training exercise. The blue team was the US military with all the intelligence in the world and with a goal to carefully analyse and debate on each tactic and event instead of taking decisions on the go. The red team was an under-informed terrorist group. Any person would have gone in the favour of the blue team but ultimately the red team overpowered the blue team despite their resources. How?
