Brain Right hemisphere is random and left hemisphere is linear? really?

For long I've seen uncountable number of blogs, websites, tutorials, booklets about career-guide, self-improvement, meditation, parenting etc. claiming;

1. "Right hemisphere loves to work random, creative way; in contrast left-hemisphere loves to follow instructions and discipline."

2. "Right hemisphere takes part in lateral-thinking; in contrast left-hemisphere takes part in vertical thinking."

3. "Right hemisphere deals with pictures, visions, senses, feelings etc; in contrast, Left hemisphere deals with formula, equation, numbers, names, letters, calculations etc."

4. "Right hemisphere works in nonlinear, meshy manner; in contrast, Left hemisphere works in linear, rigid, sequential way.

5. "Right hemisphere see the whole, big-picture. Left hemisphere see one part only".

etc.

Some example here , here, here , here, here, here et cetera.

Thus I developed a concept about behavior of 2 hemisphere.

Now While I was going through following research article (of 2000):

Cerebral specialization and interhemispheric communication by M. Gazzaniga (pdf) ,

I stuck on a diagram telling the exact opposite.

(I've slightly edited the screenshot to enlarge the text and utilize the whitespace).

The only thing of the paper maches with popular view, is; the right hemisphere is taking important part in understanding pictures, geometric shapes, extrapolating to fill a gap in an image, etc.

But according to this diagram; actually Left hemisphere is site for viewing the 'big-picture' of a subject ('living things'), finding 'similarity' (sings, eats, has a etc). Also From personal experience, the way of thinking shown as relational-map at left hemisphere, is the cause of 'randomness' in me, so that I keep many books and files scattered while working; or was broken line (que) in school to collect a grass or stone. The thing shown at left side forces me to collect various objects and arrange them... not the rightward one. Also I zone-out too-much and day-dream because of the left-one... not the right-one.

In contrast, clearly the right-hemisphere in this diagram, is processing information in much rigid, linear or sequential, disciplined way; and looking a small-part... not the big-picture.

So, please could anyone explain me, why should I still have to consider left hemisphere as a rigid linear servant and right-hemisphere as rulebreaker daydreaming artist?

(P.S. most of these popular-series's tell that Right hemisphere is intuitive and Left hemisphere is logical. But I can't believe this because I can't separate logic and intuition. Logic is the bridge between intuition and reality.)

• My point is; the popular-information is not-only myth; perhaps it is opposite in gross view. Oct 22 '16 at 13:26
• The only difference that is associated with the two cerebral hemispheres is that the left, is more suited to process language and language tasks, and the right is suited for spatial and visual tasks – which is known as lateralisation. Oct 22 '16 at 14:32
