Excerpt from Book Report: The Story of Success by Malcolm Gladwell In statistics, an outlier is a point that is far distant from other number sets, and Malcolm Gladwell applies the concept to exemplary individuals who set themselves apart from others through their actions and behaviors and who generally do things that are out of the ordinary. In his book, Outliers: The Story of Success, Gladwell describes some of the attributes he believes are responsible for some people becoming outliers compared to their peers, and cites a number of examples as being proof positive that some people take nature and nurture and run with it.
Religiosity Eye color Twin and adoption studies have their methodological limits. For example, both are limited to the range of environments and genes which they sample.
Almost all of these studies are conducted in Western, first-world countries, and therefore cannot be extrapolated globally to include poorer, non-western populations.
Additionally, both types of studies depend on particular assumptions, such as the equal environments assumption in the case of twin studies, and the lack of pre-adoptive effects in the case of adoption studies.
Since the definition of "nature" in this context is tied to "heritability", the definition of "nurture" has necessarily become very wide, including any type of causality that is not heritable.
The term has thus moved away from its original connotation of "cultural influences" to include all effects of the environment, including; indeed, a substantial source of environmental input to human nature may arise from stochastic variations in prenatal development and is thus in no sense of the term "cultural".
Please help improve this section or discuss this issue on the talk page. Individual development, even of highly heritable traits, such as eye color, depends on a range of environmental factors, from the other genes in the organism, to physical variables such as temperature, oxygen levels etc.
The variability of trait can be meaningfully spoken of as being due in certain proportions to genetic differences "nature"or environments "nurture".
At the other extreme, traits such as native language are environmentally determined: At a molecular level, genes interact with signals from other genes and from the environment. While there are many thousands of single-gene-locus traits, so-called complex traits are due to the additive effects of many often hundreds of small gene effects.
A good example of this is height, where variance appears to be spread across many hundreds of loci. The "two buckets" view of heritability.
More realistic "homogenous mudpie" view of heritability. Steven Pinker likewise described several examples: But traits that reflect the underlying talents and temperaments—how proficient with language a person is, how religious, how liberal or conservative—are partially heritable.
When traits are determined by a complex interaction of genotype and environment it is possible to measure the heritability of a trait within a population.
However, many non-scientists who encounter a report of a trait having a certain percentage heritability imagine non-interactional, additive contributions of genes and environment to the trait.
As an analogy, some laypeople may think of the degree of a trait being made up of two "buckets," genes and environment, each able to hold a certain capacity of the trait.
But even for intermediate heritabilities, a trait is always shaped by both genetic dispositions and the environments in which people develop, merely with greater and lesser plasticities associated with these heritability measures.
Heritability measures always refer to the degree of variation between individuals in a population. That is, as these statistics cannot be applied at the level of the individual, it would be incorrect to say that while the heritability index of personality is about 0.

|Nature versus nurture - Wikipedia||For centuries, the debate has existed within the psychological community and beyond concerning the topic of nature versus nurture in terms of human development and achievement. Specifically, what is the main influence on a person - their genetics or their environment?|
|Nature, nurture and exam results By Mike Baker If your parents do well, you are also likely to, Chris Woodhead says Do genes determine how well children will do at school?|
|Why do some people succeed and others keep trying — maybe even fail while at it? Why do some people find success after success while others build a tent around their former success and then get lost?|
To help to understand this, imagine that all humans were genetic clones. The heritability index for all traits would be zero all variability between clonal individuals must be due to environmental factors. And, contrary to erroneous interpretations of the heritability index, as societies become more egalitarian everyone has more similar experiences the heritability index goes up as environments become more similar, variability between individuals is due more to genetic factors.
One should also take into account the fact that the variables of heritability and environmentality are not precise and vary within a chosen population and across cultures. It would be more accurate to state that the degree of heritability and environmentality is measured in its reference to a particular phenotype in a chosen group of a population in a given period of time.
The accuracy of the calculations is further hindered by the number of coefficients taken into consideration, age being one such variable. The display of the influence of heritability and environmentality differs drastically across age groups:The nature versus nurture debate involves whether human behaviour is determined by the environment, either prenatal or during a person's life, as a reaction to the strong focus on pure heredity in the wake of the triumphal success of Darwin's theory of evolution.
Nature vs Nurture: What Makes A Successful Intrapreneur? October 30, | In Singapore, I’ve recently partnered with Fingerprint for Success, a tool that benchmarks entrepreneurial attitudes and motivations based on pretty sophisticated research.
As far as success cases go, what makes a difference in terms of personality traits and. Editor’s Note: UPDATED as of October 15, for relevance and accuracy. Here’s a fun tidbit about the old phrase “nature and nurture” and why they’re connected: Did you know that when you achieve something or are successful in an outcome, it increases the dopamine receptors in your brain, which makes you smarter and [ ].
Is it nature or nurture that makes for academic success? The striking picture that emerges is one where ability levels at the earliest age are a strong indicator of later educational success. Even when measured at just 22 months, children who started out in the lowest 25% of the ability range mostly remained stuck amongst the lowest achievers.
Nature, Nurture, Drive and Success. My wife, Temi, and I discussed the relationship between personal drive and success as we made our way to work on Tuesday, January 31, and a few things of note. Using a series of examples of highly successful individuals in the sporting world, entertainment and information technology industries, Gladwell also makes the point that individual effort counts for as much, if not more, as nurture's role in achieving success in life.
