Does Natural Talent Exist?
I propose a realistic, yet fictitious, scene for you: a master collects 10 students from around a country, or varying regions with the same spoken language, and trains them all for eight hours a day, for a total of three months. What does he teach them? To draw in concrete fashion with attention to shading and details.
Let's assume that all 10 were reasonably tested to show about the same inability to draw beyond basic disproportionate body outlines and basic asymmetric "natural shapes." All of these students had similar IQ scores, no prominent mental or physical disabilities, and had no history of attention or motor skill dysfunctions. Now let's also assume this master showed each student approximately the same amount of attention and effort to keep them practicing and gave them equal amounts of time to individual training.
The ultimate test was being able to do "figure drawing" of a subject with reasonable focus on identical details within a pencil-shading environment.
In the end, three could draw an indisputably accurate depiction of the person at hand. Three more could draw a reasonable facsimile of this person with slight disproportionate parts and varying degrees of shading. Finally, the last four had rapidly degrading degrees of similarity to the subject and even one was unable to grasp nose/lip/chin interactions.
Why would you say the last four students were unable to draw based only on this account? Is it because of lack of the same naturally inborn talents, or would you believe there was some biased parts of the story in how equally they were treated or their mental/physical conditions?
I for one, completely believe that some people who practice along side you on the same subject will, inevitably, be superior to you, and some inferior to you, in certain skills and abilities for reasons beyond your control; and that these cannot be overcome through hard work - only that an acceptable level of skill can be achieved by those with lesser talents working several times as hard to reach the same milestones.
