In today’s ruthlessly competitive international economy, the United States may benefit from a potent but unheralded advantage: the aggressive edge sustained by the inherited power of American DNA.

The radical notion that our national character stems from genetics as well as culture has always inspired angry controversy; many observers scoff at the whole idea of a unifying hereditary component in our multi-racial, multi-cultural society. Aside from the varied immigrants who now make up nearly 15% of the population, the forebears of today’s Americans journeyed to this continent from Asia, Africa, Latin America and every nation of Europe. Our stark differences in appearance, if nothing else, argue against the concept of common DNA connecting contemporary citizens of wildly divergent ancestry. .

Nevertheless, two respected professors of psychiatry have recently come out with challenging books that contend that those who chose to settle this country in every generation possessed crucial common traits that they passed on to their descendents. In “American Mania,” Peter C. Whybrow of U.C.L.A. argues that even in grim epochs of starvation and persecution, only a small minority ever chooses to abandon its native land and to venture across forbidding oceans to pursue the elusive dream of a better life. The tiny percentage making that choice (perhaps only 2%, even in most periods of mass immigration) represents the very essence of a self-selecting group. Compared to the Irish or Germans or Italians or Chinese or Mexicans who remained behind in the “Old Country,” the newcomers to America would naturally display a propensity for risk-taking, for restlessness, for exuberance and self-confidence –traits readily passed down to subsequent generations. Whybrow explained to the New York Times Magazine that immigrants to the United States and their descendents seemed to possess a distinctive makeup of their “dopamine receptor system – the pathway in the brain that figures centrally in boldness and novelty seeking.”

John D. Gartner of Johns Hopkins University Medical School makes a similar case for an American-specific genotype in “The Hypomanic Edge”—celebrating the frenzied energy of American life that’s impressed every visitor since Tocqueville. The United States also benefited from our tradition of limited government, with only intermittent and ineffective efforts to suppress the competitive, entrepreneurial instincts of the populace. Professor Whybrow says: “Here you have the genes and the completely unrestricted marketplace. That’s what gives us our peculiar edge.” In other words, “anything goes capitalism” reflects and sustains the influence of immigrant genetics.
