There are 3 Levels of Cognitive Thinking in people:

The Level 1 Base One is what we achieve in childhood. We learn about rules and live in world where we are told what to do and not do with rules to follow. The rules and our model of the world is quite simple - This equals That. Do this and this happens, bad or good. At this Level our thinking is just linking two things together and creating overly simplistic models of reality. Our thinkings and feelings are “childish” and need to evolve to where we can somewhat think for ourselves and control our feelings and so be able to live in and function in the “adult world”. Often, this thinking type is carried over into adulthood where is causes a lot of limitations and problems and conflict when it is misapplied in situations that require Level 2 or 3 thinking.
The Level 2 Modal Mind is a mind with additional choices and ideas in life. And it move from one to others in a modal fashion, i.e. it can only handle one at a time. At this Level, a person sees multiple options and paths and can generally connect them together into a string of multiple links and more complex less simple reality models. If I go to college AND get a good degree THEN I can get a good job AND have money for a good life!
So a typical Level 2 person will pick one ideology or life path from many and stick with that while then often change to something else. Often it is just a sequential path from trying this and then that without really deep thinking about these things. Level 2s often have a deeply clinging attachment to their current ideas and ideology and position. This is not to be mistaken for true Passion because they never really ever dig deep into things.
The Level 3 DaVinci Mind is a mind that digs deep and goes far beyond Level 1 and Level 2. He/she builds complex and very realistic models of Reality which they then use to solve difficult problems, do new and creative things, and achieve much more understanding and accomplishments than is possible with Level 1 and 2 thinking.
Level 3 thinking abilities allow DaVinci Minds to link things together that Levels 2s do not and cannot. And also assign probabilities and weights to them. So Level 3 thinking allows DaVinci Minds to create complex answers to complex problems and pursue paths which are not evident to Level 2s. This cognitive linking and modeling ability opens up new abilities and facilities for them and they can do many things that Levels 1 and 2 just cannot.
And to give you a bit of understanding of the significant differences between these levels, here is a Level Interaction diagram:

And here’s what they think from their perspectives:
Level 1 – You know exactly what he/she is going to say...Because it never changes...Or can change...
Level 2 – Most often indecisive...Wavers between options...Can’t seem to really figure out all the pros and cons...And the obvious course of action...”Political” considerations are judged to be most important...More important than good decisions!
Level 3 – You’ll either get an immediate Optimal Course of Action result from them...And/or they will think that you’re really asking for options...So they will give you a detailed summary of the options with the pros and cons...Far more than a Level 2 Consciousness can handle...Or understand.
This is why Leonardo da Vinci Minds must be managed by other Levels 3s...Or well-trained high Level 2s...Or work for themselves or their own companies.
