So, I say
-Are left-ies smarter or faster?
Maybe it's not about smartness but different perception and by what that means, different solutions; responds; reactions; An other perspective for a problem sometimes is enough to give an answer.
At the case of Athletes the advantage is the perception of "space" (Team sports). It is just different and surprises the (R) opponents, but no surprise for the (L) athlete, cause he used to confront with (R) persons since they usually are the majority.
I dont think they are faster. Did the majority of sprint runners are left-handed?
No, I dont know, but I dont either think so.
-More capable to certain fields like: Music; Mathematics; Psychology; Arts? etc
I cannot be certain about nothing of all that, but I am sure that all, is about perception.
The music, since you use both hands for strings; percussions; give a good dialogue beetween your particle members.
I consider the same works with dance, but I dont think for example that a (L) person is more advanced. Allthough an ambidextrous (Am) person looks benefited, it is not the real case, because he face problems; which I'll deal below.
I dont think is something special with (L) as well with (Am), or at least with me or my case.
-Is there a genetic reason behind the "lefty individuals"; or ambidextrous cases?
No, I dont think so, of course there is a reason and a fundamental one, but that -maybe- is not "recorded" up on our genetic profile from our ancestors, and it happens at real time "now". Of course there is a reason behind, but nature dont care for our left or right side, but just to put us in "motion". At that point is crucial to understand that if we try to move same time L&R feet, probably we would not walk or we will fell down. So. there is a decision that "early" we have to take in our mind, to "move" and in some extend to be ready to deal with our future tasks, at what time this decision happen I dont know. -To a prenatal period; Afterbirth;
I answer: <<the earlier the better>>.
-What is the reason that causes the effect; Is natures random choice?
I think that is the most interesting part. Yes Nature need a choice from us; to set us in move.
For the economy of the actions, we need a part (L) or(R) to "belong" and to "move" accordingly. We walk by playing an eguation beetween immovable status foot and the other foot in motion (I dont say action cause both feet are in "action", allthough not obvious.) An example with metaphor analogy Is the dot. (.) guestion like:
What is a "dot"?
Dot is an ink spot or the rest of the space around the spot?.
or
What is melody?
Melody are a series of tones/notes (action) or the silent spaces (pauses) beetween them?
I mention all that because I think that acually both sides work to all individualls and animals, but never 50/50.
Actually I think the majority of people fell up on a certain preferance (L or R) for economy of time. So usually people dont have a good second hand. Allthough there are "problematic" exceptions.
Could be (R/L ability) 70/30 or 60/40 even maybe 51/49 (for humans) but never 50/50 I think.
Why we choose our L or R side is a necessity for our evolution. As it is also to keep pattern of the "first move".
The neurons in our head take the "profit" of the action. Routine is safety and we have to survive, we repeat our method everytime because everything will go fine, like the first time.
We use the same way, we make the same mistakes and still we wondering why it happens?
But we use also the same way because we know from experiance where it ends. Isn't it pretty human I suppose. Thats the story of our evolution. I Imagine the mistake and success... walk feet by feet, hand by hand.
So I conclude that not only we have to set on a quick decision (to set in move) but we have to repeat it for being safe.
That make us to be (L) or (R). But the big question: Why left or Why right, is deep and similar to the question:
"What cause big bang 0,milisec before the explosion?"
-Well I have an idea but i'll keep that for my autobiography... (to earn some money for the ferryman) lol.
and for dessert, some of social perspective interest:
-Why parents prevent the individuals -lefty- natures; What's the consequences of that intervention?
Yes parents are making mistakes, it was interesting that other forum members mention about that issue to other countries as well. That happens to Europe only or to other places also?
The true is that dont work well for me. I had problem to recognize L from R and some times still do.Allthough I have made mine methods of verification and sometimes I have to do a double thought before. But I have good sense of space and time...
The last one is maybe irrelevant but at least is a good thing. (lol)
-Is it prejudices or a big need that set the conspiracy against the left-ies?
I first thought that was superstissions from the church; (europe christian tradition).
But I realise that maybe the reason, at the end of the day is that we just live in a "Right world".
I'll end it here because the issue is wide, (I could wrote a book)
I believe that there is a tension to be at a certain time (L) or (R) and the rest is practice.
At least for my case as experiance and percieve.
Nice Thread.
