What about intuition? It has never been titled as a form of intelligence, but would you think that someone who has great intuition in things, has more intelligence?
In some respects, intuition could be thought of as a clear understanding of collective intelligence. For example, most web sites are today organized in an intuitive way, which means they are easy for most people to understand and navigate. This approach evolved after many years of chaos online, as a common wisdom emerged over what information was superfluous and what was essential (i.e. About Us = essential).
Intuition is like a muscle. If you stimulate it, it will gain more and more strength, maybe more flexibility. However, if you never use it, or if you misuse it, the tendency is for it to become poorly developed, deformed, enormous.
The fact is that almost all of us have intuitive flashes during the day, or even during the night, when we wake up with something in mind; yet instead of turning the light on and taking a note, we decide to turn to the other side and keep sleeping ‘for it is not the moment to worry about nonsense’.
The next time that you have an intuitive flash, take hold of it, for it may radically change your life for the better!
