Nature Vs. Nurture & Cultural Evolution

Language is culture. Food is culture. Customs are culture.

They are all taught. They are all shaped and communicated across generations through group orientation and primary socialization.

In the book, Not By Genes Alone: How Culture Transformed Human Evolution, authors Peter J. Richerson and Robert Boyd explain that some scientists argue that culture and human behavior cannot be tied to evolutionary theory and biology, quoting the concept of nature versus nurture.

Culture is something created via nurture, while biology is formed by nature.

An individual’s concept of time, her values and customs, her language – all of this is formed by the environment in which she grows up.

It is nurtured.

An individual’s eye color, his height, any genetic disease he may have – all of this is formed by genes.

It is the result of nature. 

Considering this, many argue that evolutionary theory does not come into play in regards to learned behaviors that are shaped by the environment.

As we’ve discussed in many blog posts, cultural behaviors – and most other human behavior – is learned; therefore, the argument is that biology has little to do with creating it.

But Richerson and Boyd suggest that this is not the case, due to the symbiotic nature of genes and their environment.

Genes & the Environment Interact

Genes are not blueprints specifying an organism’s final draft.

Instead, the genetic information stored in an organism interacts with the environment around it while the organism is developing.

As Richerson and Boyd describe it:

“Genes are like a recipe, but one in which the ingredients, cooking temperature, and so on are set by the environment.”

And like any recipe, the traits of the organism will vary based on the differences in the environment.

Some traits are more affected by environment than others.

For instance, most humans develop two ears, despite the environment they’ve grown in, but depending on their nutritional environment during youth, they can develop different growth and health outcomes into adulthood.

Environmental differences can also cause differing behaviors in organisms that are genetically the same.

In such circumstances, the environment is the direct cause of different traits and behaviors.

And because culture is both a part of the environment and a reaction to it, while genes are the evolutionary response to past environments, neither can be removed from the equation.

They are symbiotic.

We’ll take a closer look at the degree to which genes and culture influence human behavior next week.

How Time Orientation & Chronemics Impact Queuing & Workplace Culture

Chronemics, which we described in a past post as the study of time’s role in communication, directly correlates with time orientation, discussed last week.

Knowing that some polychronic cultures view time as cyclical and sometimes don’t even have future tenses in their language, you may have guessed that polychronic cultures are often past-oriented.

Monochronic cultures, on the other hand, are largely future-oriented.

Here are a few ways in which chronemics direct cultural behaviors.

Queuing Culture

queue

Have you ever queued up in a foreign country and been cut in front of?

If you have and immediately thought to yourself, “how rude!” then you’re probably from a monochronic culture. Monochronic cultures are often cultures of law and order.

As this article by Leon Mann, “Queue Culture: The Waiting Line as a Social System,” published in American Journal of Sociology writes:

“Cultural values of egalitarianism and orderliness are related to respect for the principle of service according to order of arrival which is embodied in the idea of a queue. The importance of time in Western culture is reflected in rules relating to ‘serving time’ to earn one’s position in line, and to the regulation of ‘time-outs.’”

Remember, monochronic cultures – like the U.S. – are also cultures where “time is money.” So, essentially, if someone cuts the line, individuals in such cultures might consider this behavior as theft of time and/or money. The offender is essentially saying their time is more valuable than that of those they’ve cut.

Polychronic cultures do not queue orderly, if at all. They crowd and scrap their way to the front of the line. In fact, cutting in line is almost a sport in such cultures.

Although even some of those who are of polychronic cultures might get upset when cut, the queueing culture (or lack thereof) is, more or less, accepted.

Actions & Their Consequences

Another way in which chronemics and time orientation impact cultural behavior is the consequences of certain actions at work.

The chart below highlights some examples:

Monochronic cultures are deadline-driven and task-oriented regarding both negotiations or projects. And, more often than not, the hierarchy within the organization is enforced.

For polychronic cultures, a deadline is just a suggestion, and negotiations don’t end until an agreement is made. Even then, the contract is amendable.

Moreover, organizations are interaction-oriented, rather than task-oriented, and the hierarchy within the organization is not as rigidly enforced if one even exists.

We’ll look at these ideas in action next week.
