The article very lucidly explains the mental framework of an individual in terms of risk and risk-taking aptitude and attitude.
Every decision that is taken carries an inherent 'push' form the intuition - some times the share of this element is 100 % , but it can never be turned to Zero. Whatever data and analytics one has at the command, one can TAKE a decision only if one listens to intuition, if one keeps on reasoning, well, one will keep on reasoning only.
One way to rationalize, as the article so lucidly explains, is self-validation.
So, the stronger the intuition, better you are equipped to take a decision (and hence a risk).. And more you allow the intuition to absorb rationales around you, quicker you will take decisions.
