How do heredity and environment interact to influence intelligence scores?

There could be various ways in which heredity and environment influence intelligence score of a person.

Explanation:

According to the psychologists and researchers, heredity and environment play an important role in the intelligence of a person. It says that an individual's intelligence depends on both the factors i.e, genetics or heredity factor (inherited from parents) and environmental factors (experience). Therefore, it has been studied that environment can have both negative or positive impact on a person's intelligence score, for example, if a person studies in a good school then he or she might have good communication skills as compared to the child who has studied in not so good school.

All citizens throughout all of human history have faced the uncertainties brought on by unemployment, illness, disability, death and old age. In the realm of economics, these inevitable facets of life are said to be threats to one's economic security.

For the ancient Greeks economic security took the form of amphorae of olive oil. Olive oil was very nutritious and could be stored for relatively long periods. To provide for themselves in times of need the Greeks stockpiled olive oil and this was their form of economic security.

In medieval Europe, the feudal system was the basis of economic security, with the feudal lord responsible for the economic survival of the serfs working on the estate. The feudal lord had economic security as long as there was a steady supply of serfs to work the estate, and the serfs had economic security only so long as they were fit enough to provide their labor. During the Middle Ages the idea of charity as a formal economic arrangement also appeared for the first time.

Family members and relatives have always felt some degree of responsibility to one another, and to the extent that the family had resources to draw upon, this was often a source of economic security, especially for the aged or infirm. And land itself was an important form of economic security for those who owned it or who lived on farms.

These then are the traditional sources of economic security: assets; labor; family; and charity.

The Rise of Formal Systems of Economic Security

As societies grew in economic and social complexity, and as isolated farms gave way to cities and villages, Europe witnessed the development of formal organizations of various types that sought to protect the economic security of their members. Probably the earliest of these organizations were guilds formed during the Middle Ages by merchants or craftsmen. Individuals who had a common trade or business banded together into mutual aid societies, or guilds. These guilds regulated production and employment and they also provided a range of benefits to their members including financial help in times of poverty or illness and contributions to help defray the expenses when a member died.

Out of the tradition of the guilds emerged the friendly societies. These organizations began appearing in England in the 16th century. Again organized around a common trade or business, the friendly societies would evolve into what we now call fraternal organizations and were the forerunners of modern trade unions.

In addition to the types of economic security provided by the guilds, the fraternal organizations and some trade unions would begin the practice of providing actuarially-based life insurance to their members. The friendly societies and the fraternal organizations would grow dramatically following the Industrial Revolution. By the beginning of the 19th century one of out every nine Englishmen belonged to one of these organizations.

Among early U.S. fraternal organizations that we are familiar with even into the present day were: the Freemasons (which came to America in 1730); the Odd Fellows (1819); Benevolent and Protective Order of Elks (1868); Loyal Order of Moose (1888); and the Fraternal Order of Eagles (1898).

The English "Poor Laws"

As the state began to assume responsibility for economic security, the English began the development of a series of "Poor Laws" adopted to provide help to the poor, as the problem of economic security was seen primarily as a problem afflicting the poor.

The English Poor Law of 1601 was the first systematic codification of English ideas about the responsibility of the state to provide for the welfare of its citizens. It provided for taxation to fund relief activities; it distinguished between the "deserving" and the "undeserving" poor; relief was local and community controlled; and almshouses were eventually established to house those on relief. The law was at once both generous and harsh. Generous in that it acknowledged the government's duty to provide for the welfare of the poor, but harsh in that it viewed the poor as highly undesirable characters and treated them accordingly.

There were a series of changes and "reforms" of the "Poor Laws" over the years, but this essential structure was the tradition the pilgrims brought with them when they journeyed to the New World.
