Southies and Tamils in general like to claim that they are more Intelligent. This is an attempt to say how. I realise this might annoy many out there..but to those people I say..you wouldnt complain about me saying that north indians are more attractive – which i have in my other blogs. I believe that indians are the most intelligent people in the world. 1)Amount of thoughts one evaluates/processes simultaneously & balance of thought : Certain people(also neotenous people), at a given time have less things on their mind…they evaluate lesser amount of things (other thoughts or brain activities) while formulating their thought. This can also be termed as brain activity in terms of number of activations and flow of different thoughts in the brain. A child who wants chocolate thinks only about the chocolate( only one thought) But a parent is evaluating a number of things such as good/badness, the cost, the effort, the right thing to do for the child etc etc. This ability to consider all aspects,side of things leads to maturity, ability to judge better and a balanced behaviour. I mean, its also not exactly thinking about it different thoughts simultaneously or inparallel…..but somehow they think about every associated aspect/factor pertaining to something by means of well rounded thinking every moment of their consciousness. This ability of well-roundedness is in the neural structure of your brain(genetic and conditioning/nurture), where strong and connections are made between associated things and so that one thinks about a particular thing,all associated relevant things also comes into mind(refer’my idea for a robot post). Actually even for the below factors/way of thinking too, its about how well two things get associated in the brain and thought flows, but I guess the difference is in the orientation of the flow of activation/thought which i will explain.So this comprehensive association /taking into consideration and bringing in all associated aspects pertaining to something is important and people who do not posses this ability but go on to construct deeper logic become quite imbalanced..like those Phd cookoos who get possessed by an illogical construct or in another type of issue sometimes fail to focus on all aspects of their life. People with the ability to consider all aspects of an issue are generally not self-centred and are able to put themselves in others shoes. Their tone of voice is also more humble and mature as they are considering how they sound to the others and dont wanna come across as boorish or self-righteous. While dealing with any issue/concept..they always recall and evaluate all things associated with it and based on that – form a reasoning or inference. Maturity basically means acting appropriately..the more factors you consider, the more appropriate your actions will be(I mean considering more factors also leads to a deeper logic 3A and thus help in a appropriate action). It can be made out from their uninhibited and confident tone of talking that north indians process lesser number of things while articulating, and the whites are considering even lesser things than indians. I suspect that people who have been insulted,punished,reprimanded or let down in anyway more often while growing tend to consider a lot more things before they speak as they are a bit more mindful/aware of not getting a desired response from the others. Hence people who are not as attractive/admired consider/evaluate a lot more factors. In the case of south indians factor 6 below also comes into play where everone in the society is preconditioned to a deep and mature thought and way of carrying themselves such as being very calm, speaking softly and being less aggressive, forthcoming or childish and more inhibitive/curbing of their enthusiasm n stuff. But apart from the impact of society/environment, the natural ability to consider different factors also comes inherently/genetically. These are generalised scores.Some individuals of a group may exceed the avg value mentioned. 20 doesnt mean no room for improvemet. When I mention a group, its not about if they are urban or rural dwellers, its just the picture that comes to my mind abt tat group. for example whn i say tamils – i mostly think about ones from chennai and asian may refer to a mix of FOBs and second gens living in west that i ve come across. Africans – a combo of african africans and afro-american in combination. Africans – 9 Chinese – 12 White Europeans – 11 Jewish- 13 Arab – 13.5 NI – 15,16 BE – 17 TA – 20 MA – 18 TE – 18 KA – 18 2)Correctness of complex logic/direction: its that ability to rightly associate things or investigate/think about it thoroughly before associating things to form a logic. It also means understanding/interpreting what one reads/sees/hears in the right way. having a good vocabulary( remembering is another aspect of having a vocabulary, but this is about the application aspect. Also i do not consider remembering ability to be an major aspect of intelligence) and eloquent writing are also the effects of having the correctness of learning the rules and applying those rules. People with a lot of pre-conceived notions,closed minded people and biased people in denial all get this wrong – despite thinking a lot. No saying if one group gets it correct than the other on average. This is becoz people who only have simple things on mind will get it right most of the time, and people who have many things on their mind or have deep thought all the time are prone to have logical fallacies. But To evaluate correctly one must also first consider all factors behind it and apply your logic correctly although the higher the number of factors to consider..the complex the logic gets and more prone to logical fallacies. I mean, maybe if one were to analyse the IQ scores of shape association there might be some insights there. But being able to consider a lot of things in mind- despite making someone prone to errors, that ability i guess would also make some one process/evaluate a lot of things and make a right association. So the above scores are also applicable this section. I mean lets consider a basic – getting it right scenario. Lets say going for option 1 helps 20 people and going for option 2 helps 100 people in the same amount. There it is easy to determine option 2 as the right option. So for every single option/point/logic/factor the brain associates and amount of goodness/sense/appropriate consequence etc. The amount is not always a number but just a cloud. So when you consider many different factors, this sense/consequence cloud gets more weightage towards a particular decision/thought/point towards which your thought further flows. So this is why the correctness ability also depends on bringing in/associating a lot of thought and consequently bringing in/associating the corresponding logical/consequence amount-cloud with it. 3) Depth and breadth of thought : depends on how one has learnt/constructed a deeper logic using their ability. Breadth of thought is how many different concepts one is able to bring into a thought, whereas the depth signifies the level of each of those concepts – there are some concepts which are quite basic, whereas some are more advanced.Within this, constructing deeper thought is more tougher than concocting a number of things into a theory. Even people who have lesser brain activity might have focused a lot and constructed a deeper/broader logic. For example the theories of someone like rajiv malhotra are more profound than that of lets say gurumurthy. Examples of the breadth of thought is- drawing analogies, bringing in a lot of facts on a related thing – for example when one talks about neoteny – its features, how its applicable amongst animals, and all those observations regarding that particular concept. Whereas when one talks about Depth, its will be like talking about how neoteny is thought to have became embedded with social structure and impacting the geo-political and the everyday scenarios today and those implications(Where one drives the thought towards a new inference and thus comes up with a logic/concept in doing so) . The breadth only means different simpler concepts which are quite apparent. The difference between 1 and the breadth in 3(B) is that in 1 you are considering all the factors that impact your decision on a particular thing. But in 3, its only different concepts, which do not necessarily bear an impact on each other, but those which are just associated in whatever way to each other and can just be concocted to form an essay or something. In short 1 vs 3B is Factors vs related facts/things. Another example to differentiate depth3 A from 1 – When rajiv malhotra talks about how ancient knowledge from india is being passed on to foreigners who take it abroad, repackage it and sell it back to indians, he talks about a deeper process of how this U turn happens and leads to indianness being digested/lost in the western international framework . An example for 1 would be how judges work by taking into account everything or how the planning commission works or the budget is made considering all the factors and perspectives of the society. well assessing the need and allocating of funds is 1, but an elaorate plan to create/build something to address things will be 3A. Another example is when someone talks about the religion 1 is taking into consideration all known facts/points/aspects about what it is and the factors that impact it. For example thinking about/taking into consideration how religion came out of man’s lack of better explanation for forces, and that it reduced violence and barbaricness and the fact that a lot of philosphy and scientific/healthy practices got embedded into it. whereas a 3A would be about inferring or implying something less obvious like how it impacts other things like politics,human behaviour in current day situation. So basically 3A is the new inference/insight/depth one formulates in his mind, which can be used in the future as 1(factor) driving other thought. So to any thought you construct,there is the base of factors accounted, length and breadth of logic. It can be imagined like a cone whose base is 1 and its height denoting the depth mentioned in 3 A(breadth of 3b is just a collection of other smaller cones/thoughts that occur adjacent to the main thought). Each of the factors themselves may have sub factors and represent a certain depth of thought(like 2,8 in the below diagram). The diagram and the connections is not accurate to whats being explained but try to picture this – When one starts his thought with the point 4, the factors(1) that a mature person brings to the picture and evaluates are 5,6,7 and possibly 3 as well(the connection is not obvious). An immature person may not be able to think about all the relevant factors(points 5,6,7,3). So by considering the comprehensive factors, they might arrive at a new thought point 2 and it goes higher/deeper into 1 this way. So thats the depth 3A. Regarding 3b imagine someone in point 4, and assume that point 10 is another thing associated with it something like thinking about cricket, to australia to dil chatah hai movie or something – a bunch of things associated with one another. Young, light headed people keep jumping across different associated points(3B) without dwelving deep into one thought area like mature ones do. And consequently are more fun for the others coz they can keep talking about a lot of stuff and be fun or interesting. But in the end, they stay in the same thought level, dont realise a greater depth of logic or something new, by traversing along the same thought points that they are already aware of – unless somewhere they stumble/drift into the logical depth component as well in that process. It is also important that they are able to have correctness of logic(in the above case would be like relating to logical/thought points correctly). other wise they are just constructing a deep bullshit or irrelevant points to the issue you are discussing.Considering a lot of factors (1) is important, but also rightly evaluating the factors to consider (2) to construct the theory or address(or ignoring inappropriate points) an issue is also important. Any theory will have to account for a number of factors and also associate several concepts/train of thought to achieve a depth. This is the primary recognition of intellect such as nobel prize winners/inventors and other intellectual achievers have all constructed a great depth(3A) of thought for which they are recognised as such. Also understanding a complex theory/a bigger picture is also based on this ability, however constructing a new complex logic is much harder and higher than understanding existing complex logic. Actually when i say considering/evaluating different things regarding something, there are not parallel thought processes that happen. Thought is always linear, its just curled up like a spring to cover different areas to sorta give rise to the thought cone described above. to give you a better picture, consider the below images When we start to think of something,it starts with the apex of 1st image. And the same linear thought process covers up a whole length(3) and spectrum(1) of things. Generally speaking the thought process has the orientation of image 2. We start from a thing(at the apex) and in our brain, there are connections and weightages associated between related things to the original thing, and in a spiral-linear fashion we think about all those things and bring them to-gether to evaluate. So we start with point D and bring to-gether the factors associated A,B and C. So A,B & C are factors directly associated with D with higher connection weightage(as created by the hebbian rule). So bringing in all these facotrs into a thought process is skill 1. Now depth is again spiraling down and reaching the depth – point E which is associated with C but not originally or directly related to original point D. The difference between 3A depth and 3B breadth is that, 3A is the process of getting to point E, whereas 3B is the process of getting to some other point associated with C lets assum X(not in picture) which has no bearing on the direction D-C-E. Thats is X is just in the level of the line ABC and related to C (or maybe even D and A,B) but DOES NOT CONTRIBUTE toward the path of getting to thought E. The factor 5 is something Y in a totally different thought cone that may very remotely be related to C but not at all related to any of the thought points in contentions -A,B,D and hence also has no bearing on getting to the depth E. I mean 5 is a jump to a completely different thougth area/domain for example talking about the cricket match in australia to world war 2 all of a sudden. So 3A is the only component where thought/logic is constructed keeping the original thoughts in mind, or rather STICKING TO THE POINT. So at the end of this thought process, the person has learnt something and has acquired a logical depth associating point D with E. If this person had high component of 1, the next time he thinks about D, he will also bring in E along with all the other factors(A,B,C) while evaluating things, otherwise if he is an immature,childish person..will be quite narrow minded and only bring in point C when thinking about D the next time. Actually one doesnt always have to strictly follow a linear path to make the association between D and E. Some people always try to relate things to certain topic. For example, for a patriotic person any issue.like immigration,legislation, culture or anything at all(which would be D), he will somehow try to keep in mind the national interest (E) and try to relate that concept D with national interest (E) and focus his thought in that Direction. This happens becoz even though the hebbian weightage is low between D and E initially, the person is a patriot and the area E generally gets more activation time and hence he frequently brings E into the things he thinks about and thought frequently spiral towards E (using the hebbian way). People who bring in a lot of factors (1) will also be positioned to drive a deeper thought, as considering a lot of thought will help get to the depth. So the 2 things that drive Intellectual depth 3a are 1) a persons interest in high funda stuff(like philosophy/national interests) and 2) Ability to hold and process as many thoughts(which is also the requirement for factor 1) )that helps them drive a deeper association/logic while also staying to the point. Probably a larger/more folded neo-cortex or the appropriate weightage/neural connections/activation potential to do this processing in neo-coretex(or the appropriate area)….which is determined by genetics as well as nurture/conditioning from the up-bringing environment/background. Just to reiterate in a different way…1)Amount of thought..considering all associated factors covering a larger area/spectrum of thought….also includes deeper/higher logic in each spectrum.3) Deeper thought involves not stagnating in one thought area but healthy enough to keep constructing/associating with things related/known/comes to mind or to think of a logic that is quite deep. People with higher component in 1 are able to pay attention/consider a lot of things like everything that is said, the speakers tone,demeanor,and things to consider like etiquette,morality, etc etc. People who are deep thinkers may become quite inconsiderate/absent minded regarding some of the above things.because there is a trade off between the components, when there is more activation focused on one section the activation is less in the other section of the brain. This is probably why a group like telugus who have a higher component in 1 do not necessarily go on to construct deeper logic with respect to a subject..they make good I.T. people but not good inventors or creators of ideas. However, whites due to their knowledge can go on to construct new concepts, and bengalis due to their inherent potential and neotenous mind can go on to construct deeper/new logic. Since Im biased towards tamils, im gonna say tamils have high potential and the brains structure to have higher processing ability along both components 1 and 3A. Both depend on ability to associate things and construct a larger thought. The difference is 1 involves processing every thing that comes to mind wrt an issue and make a comprehensive assesment whereas 3 involves having a direction/objective and construct thoughts to formulate a plan/solution. 1 is simply recalling things we have thought about before and already associated. 3 is making a new association between 2 things in your head. 3 is obviously the new thought you are generating and the most rewarding brain activity. Obviously to imagine and associate things, you gotta have knowledge,education,exposure and those nurture factors mentioned in 4. Person who has 1 but not 3 is a good developer/engineer. So please dont say chinese should score high on 1 now coz chinese are just hard-working and not so high inherent potential. Writers usually have a lot of 3B component in their work whereas scientists and thesis contains a igh 3A comonent. And europeans and jews may look like they are onto deeper stuff, but its only becoz of war,wealth,knowledge,exposure and being in a modern developed societies with a lot of things going on..so the orientation/society(4) factor helps then – not that they are inherently capable of generating more thought than indians. person who has good 3 but not 1 is a philosoper or in some cases artists…and then there are inventors and geniuses who are strong in both components. For these things again you need a lot of thinking potential/brain activity to drive deeper thought(so people who consume spicy, healthy,fishy things have more activity on general). not only thinking potential but also correctness of logic and evaluate a lot of factors while constructing the logic. And also a good brain structure through your genetics to be able to construct deeper thoughts. This also depends on the background in which you grew up/learnt ….conditioning from the way people around you construct logic and behave also influences your ability to construct logic. Trying to pen down all the things required in the brain, 1) A lot of activation(or thought current/voltage) : The more ions i the elecrolytic solution in the brain..the more activation potential you have. after all the activation is the thought. These Na, K ions are present a lot in salt/spicy food. There is also a saying in tamil ‘dont you add salt in your food?’ meaning ‘dont you have any shame/realisation in you’?. So more activation potential you have in your brain your gonna have more excitiation/feelings/thoughts. People with less activation are ofcourse quite dull..so go eat spicy food. The other factors influence the orienatation of thought. I mean with just a high potential in your brain, if the potential is just concentrated on one area alone..thats just all your thought concetrated on a simple area…like for example kids, when then are eating chocolate..they enjoy the chocolate a lot more than adults do but are thinking only about the chocolate . If someone wants to come up with a theory of everything, he needs not just the activation, but the activation oriented into different thoughts..for which the below brain structure comes into play. 2) Activation threshold of neurons : If the neuronas are healthy, they have a lower activation threshold…so even with limited activation thought flows in that neuronal path. This property may also be inherited genetically. if a lot of areas of brain have healthy neurons with low threshold thought flows into them . people with healthy omega 3 fatty acids consumption can have such healthy neurons and so more thoughts flow in their mind..potentially leading to a higher component of 3A, 3B
3) easier Association between neuronal connections: Neuronal connections have weightages associated to them. If the neurons are healthy, the connection weightages is also high. The connection weightages between neurons /neuronal pathways/different areas also increase according the hebbian rule (via learning ), and this weightages property is also passed through genetics. In other words, the neural connections/pathways have to be strong in the brain – inherited from genetics.This drives the Higher component 3b of tamils/south indians – their genetics and culture/mannerisms/way of thinking.
4) Number/Density of neurons : More neuronal density in certain sections of the brain(gotten from genetics mainly, and nurtured by effort and learning) allows the people to be able to process a lot of thought in that area(be it musical or artistic or scientific), or if in general they have higher density in the neo-cortex, they have higher thought processing ability overall. So this affects 1 and 2. I guess southies have a high neuronal density which enables them to bring in a lot of thought and be heavy headed instead of light headedness.
Features 3 and 4 (the number of neurons and higher associative connections between them) passed on through genetics is what increases their maturity level and ability to bring in a lot of thought amongst south indians. For non-south indians since they dont have too high neuronal density/deeper pathways, their activation is not wasted/diluted in several neuronal connections in one particular thought area and neither does it go too deep in any their mind wanders,jumps to different thought areas easily and over a period of time, their mind is trained to traverse different thought areas hence they are able to generate a bit of deep thought. So when learning or thinking about things, South Indians look at the totality of things whereas north indians just think about the main point alone. But for non-tamil south indians, they have factor 1 and 2, but since their activation is diluted in these areas, they are not able to drive deeper thought, instead they dwell on a thought area but thinking about it comprehensively compared to northies. However, tamils are able to drive deeper thought as they have higher neuronal density(4) and even higher connection strength(3) as a result of which thought is able to flow out to other regions instead of stagnating and consequently able to think deeper. Apart from the above factors, if you are exposed to a lot of concepts-scientific/hi funda, knowing a lot(factor 4 mentioned below) will also enable one to construct deeper logic. thats why people in developed countries with good education,information and knowledge are able to thing about deeper things and come up with a lot of ideas and concepts. But apart from the impact of society/environment, the natural ability to consider different factors also comes inherently/genetically.
neuronal density helps in factor1
connectivity between areas affect factor 3b
knowledge helps factor 3b
activation, threshold(health of neurons) help in activeness, fluidity
These are generalised scores.Some individuals of a group may exceed the avg value mentioned. 20 doesnt mean no room for improvemet. Africans – 13 Chinese/Asians – 12 White Europeans – 16 Jewish- 17 Arab – 15 NI: 17,18 BE: 19 TA: 20 MA: 19 TE: 18 kA: 18 To recap.. The above 3 are natural/inherent abilities determined mainly by genetics , how one has conditioned their mind to think(reflection of the background) and also healthy brain activity by means of healthy consumption.To tackle a complex concept..many abilities need to come together – the depth, the correctness, and considering all factors . A concept/thought that has depth and is correct in logic is not necessarily a comprehensive one if it doesnt take into account the third dimension. For eg.rajiv malhotra may have the depth and correctness, but just by the way they speak one can feel that someone like gurumurthy considering a greater breadth of things in his mind while putting forth a point. Also there is a difference between amount of thought/factors considered simultaneously(1) and the amount of thought. Amount of thought is simply just pondering a lot about superficial stuff without a great depth of logic,correctness of logic or processing a lot of factors simultaneously. This amount of thought is particularly high for young/neotenous minds..u know they say they have a lot of imagination and fancy things on their mind(which is similar to 3b – breadth of thought or 5)kinda thing….. they dont really dwell on a particular thought area but think about different things associated and ponder a greater breadth(3b/5) of things in their mind.To differentiate the process in young vs old peoples brain, In old peoples brain many thoughts(the neural pathways representing them) have really strong associations with each other and with certain other thoughts. This means people get to these thought areas very easily and stay in these thought zones/areas for a long time as they have stronger weightage in that section of brain. In young peoples mind, no thougth area/zone has relatively high neural connection/association weightage and hence they move to different thought areas easily. As people grow up, they should develp the ability to create this neural connection/association weightage(learning is the process of creating neuralconnection weightages) in such a way to create deeper/wider logic thought flow and memory properly. people in whose brains these connection weightages are creatd well become good thinking people and the ones in whose brain, these connection weightages are not formed well either because of genes or nurture or conditioning become not so bright people.People who consume a lot of spicy food/fishy food/heahlthy brain cells development also have higher activity in the brain..which depends on these age and health factor mostly..nevertheless there is also a gradient based on the different groups..i mean Tamils or bengalis generally may have a higher brain activity compared to lets say a punjabi or a kannada, but it also depends on age and health too..so its difficult to come up with scores for these. This along with the memory factor depends on age and health and so not making a generalised scored for these and not considering these as primary intelligent quotients In the end, components 1,2 and 3a,b are all thoughts/neuronal activation in different orientation.Which means anyone who puts an effort can exceed in those components.and their brain structure(genetic) and conditioning/nurture from background helps too. The below are aspects depending on the society where they live and access to inputs/information(nurture). 4) Number of things they know(knowledge):So people receiving good eductaion/inputs from being part of a knowledgeble circle/city with exposure will know all the important/sophisticated hi-fi things and whether your city has good education,knowledge and ideas floating around(whereby you get the knowledge-building blocks to form new ideas). this also helps them in formulating complex/sophisticated/hi-funda thoughts. one indicator of this ability is the amount of time and effort people spend in browsing/acquiring new information across any field. These are generalised scores.Some individuals of a group may exceed the avg value mentioned. 21 doesnt mean no room for improvemet. Africans(in africa) – 11 Chinese – 14 White Europeans – 20 Jewish- 21 Arab – 13 NI: 18 BE: 19 TA: 20 (engineering,nobel laureates, and education level of chennaiites) MA: 19 TE: 17 kA: 16 5)Number of new things they think about/amount of brain activty: Sometimes..even people with higher activity potential,deeper & correct logical thinking ability..do not necessarily think about many different things, for reasons such as they might be very conservative and are not very keen or inquisitive about other things. They are just happy thinking about the same things again and again..or rather forced to be that way becoz of work/society(..imagine a I.T. developer vs a bohemian artist), and appear as if they arent generating different/a variety of thought. For example monks living simple life and having simple thoughts. Neotenous/childish people do not curb their thinking and generate thought about different things and there fore may be one up compared to a conservative person based on variety of their thinking. People having fun and exploring new areas score high in this.respect to a particular thing/thought, whereas here its about keeping an free mind and observing/wondering about a lot of things they come across. The pattern of this thought is similar to 3b, the small difference is in 3b its about associating different things with the particular concept/thought in contention, whereas this is about making an conscious effort to explore different things. This is reflected in the importance to art/novelty/culture/celebrations given in the society also considering the economic constraints. These are generalised scores.Some individuals of a group may exceed the avg value mentioned. 20 doesnt mean no room for improvemet. Africans – 11 Chinese – 12 White Europeans – 19 Jewish- 20 Arab – 13 NI: 17,18 BE: 19 TA: 17 MA: 18 TE: 17 kA: 15,16 The developed, rich and multicultural countries obviously have a lot of interesting stuff going on.Closer scoes doesnt mean that certain indians’ thought is similar to western thought – they think of drastically different things/issues in the west and here. But things are also a bit eventful and a lot going on here in India. 6)Prior Exposure and conditioning with Deeper thoughts/philosophy : South indians’ thoughts are predisposed and skewed towards maturity..They are conditioned(by society) to feel right about being less aggressive..less aggressiveness being associated with maturity. So exposure to high funda logic from their society..will steer their thoughts in the right way..and will help them in achieving a superior logical position.for eg. how people and everyone in certain societies are influenced by religious or other philosophical teachings followed by that society. So some south indians truely understand why its good to be mature, however a vast majority(who do not exercise much thought) are just mature because sub-consciously it feels right and appropriate in that society and sub-consciously get to that higher logical position. This is not the same as the impact of ones background in the way they generate/construct logic or thought mentioned in 3 These are generalised scores.Some individuals of a group may exceed the avg value mentioned. 20 doesnt mean no room for improvemet. Africans – 10 Chinese – 18 White Europeans – 11 Jewish- 15 Arab – 16 NI: 16 BE: 17 TA: 20 MA: 19 TE: 19 kA: 19 May be a lot of SE asian communities exposed to South Indian rulers have a maturity level of 18 a reason for the southies to occupy the moral higher ground is the aggressive and self-centred nature of northies. It is well know that southies are more mature/passive whereas are northies are more aggressive and forth-coming. In a north indian circle,a few of the good looking centre of attractions dont really care about how they make the others around them feel. When they are the centre of attraction, the other have to resort to being the not -so preferred/invisible losers and have to pretend to have fun by being an extra/ a side-kick to those aggressive ones, despite feeling bad inside…for eg the girl wearing the green shirt in 00.22-00.23 – look at how superficially she is shaking her head and made to look like a fool
north and south Indians are culturally and genetically closest to each other compared to any other ethnic group like say persians or arabs… The differences in intellect are primarily are brought about from the physical differences and only to a small extent based on history..for eg. the guptas or magadhas or mauryas before covered all of what people consider the northern part( i mean the marathis and orissa up to kashmir,indus in the north-west front) ..and so that belt was sorta were culturally similar. Even in the hottest places of the northern belt, they had a mix of both hot and cold seasons..as in if it was hotter for 9 months, at least for 3 months they had cold season. The cold weather makes muscles stronger and firmer and also gives rise to firm/sharp and neotenous features. This mix of climate is very good biologically speaking in contrast to an monotonous climate. And in the south, the climate was mainly hot with the exception of hilly regions and it does not get as cold and chilly as it gets up north. This makes skin,musles dry and saggy or slightly puffy features – however you would describe it. These skin n muscles never get a chance to firm up as there are no cold seasons in the year. And so the physical features of south indians are less neotenous(youthful is the simple translation)..like non-flatter face, bigger eyes, lesser distance between eyes, nose and mouth compared to the rest of the facial area, dark dry and thick skin etc. One cannot claim that physical neoteny will not have any effect on the intellectual neoteny of people. A society, of group of people where its people have a lot of neotenous features will feel and act more neotenous and thereby making the culture of the group more neotenous, and the neotenous culture(with more singing,dancing, liberal attitude, forth coming and aggressiveness) will also shape and re-inforce neoteny in the physical looks and the faces of its people. So even a smaller percentage of physical differences can sometime lead to a lot of differences..for example a society where there are 60% physically neotenous people-their culture is mainly going to be neotenous. Whereas a society where 60% of its people have mature physical traits and 40% noetenous traits..here the culture of the society will tend to be more mature. And if the culture is mature, the later generations will be more mature and if the culture is neotenous, the later generations will be more neotenous. the community of deepika padukone..gowd saraswat brahmins..even though they have nice and fair features, they are quite mature because of the cultural closeness of konkani with kanada and south, and hence deepika comes across as distinctly mature as comapred to someone from maharashtra- closer to karnataka border. The only north indian actress who strikes me as a mature(not naturally neotenous in behaviour) person is madhuri dixit. I cannot think of any south indian actress who is not mature(vineetha thottumkal maybe). Some other examples of how the culture you are in affects your look. When i try to look for mudaliar brides in Bharath matrimony, I can notice how some of them born and brought up in the north, with not too strict of parenting look more cuter and look just like north indians. If you browse saurashtran profiles( who supposedly settled in TN some 300 years back), they look very similar to south indians despite having fair skin. And take the examples of Madhavan and swara bhaskar or meghna naidu, they look and act more of north indian than typical south indian faces. Like I said before , it is all thought oriented in different ways/directions. Two people having the same amount of activation potential in the brain might focus and direct their potential in different ways (1,2,3a,3b or 5) leading to different personalities(although it also depends on the structure of neurons in the brain which determine the ease in which direction the thought might flow) and so any group, if they can focus enough achieve a high score in any of the above factors. In other blogs ive discussed about nice guys finishing last and why people who think too much/geeks/nerds are not really that fun. To explain this with the above components, intelligent/nice/mature guys have higher scores/orientation components in 1 and 6. 6 is especially a fun killing component as it deals with the code to conduct oneself in the society ,discipline, maturity and stuff. 6 kinda kills the spontaneous thinking that comes about with the 5th component and 1 is a drag on 3b. 5 and 3b are the components of neoteny,being spontanious, interesting and fun thoughts, whereas 1 makes a person dwell/stagnate in a particular component and think about it thoroughly like nerds. This is why south indians are doing well in technical/I.T. / law etc .3a(depth) is also good, if the thought is a fun thought – like some nice poets and writers have good scores in this component and they are comparitively fun/romantic people too. However if 3a(depth) is in a mature/nerdy thought, that works the opposite way – like it does for tamils – not in their wit(mean to say they have good sense of humour) but in their philosophical(like conservatism,tradition,patriotism) part.and 3a works in a good way for bengali girls and make them very engaging and fun. The areas and the scores may be updated as i get to think about it more.
