Analyze how technology influences economic, political, ethical and social issues and weigh the trade-offs and consequences of technological decisions

Learning goal: Explain how the development and use of technology influences economic, political, ethical and social issues; explain why technologies inevitably involve trade-offs between costs and benefits; and analyze how decisions about the use of products and systems result in intended and unintended consequences.

Technology, development and use. Technology is the application of knowledge to make tools, products and systems that serve human purposes. The first statement distinguishes development (inventing and building a technology) from use (how people and societies adopt it). The distinction matters because the same technology can be used in very different ways. Nuclear fission, developed in the 1930s and 1940s, was used first in weapons and later to generate electricity. Decisions about development are made largely by scientists, companies and governments that fund research; decisions about use are made by everyone who buys, regulates or refuses a product.

Four kinds of issue. The standard names four arenas in which technology has influence.

Economic issues concern production, jobs, prices and wealth. Successful new technology can raise productivity, the output per worker, which over time can support higher living standards, although the gains depend on how well it is put to use and on who receives them. It also changes which jobs exist. Mechanized farming in the twentieth century let far fewer farmers feed far more people, and most rural workers moved to other jobs; the change raised national output and was painful for many families. Mobile phones let people in places with few bank branches send and receive money: a mobile-money service launched in Kenya in 2007 became widely used there, giving many people their first access to financial services. The service began as a pilot for repaying small loans; when pilot users unexpectedly used it to send money to one another, the company redesigned the 2007 launch around person-to-person transfers, so an unintended use in the pilot shaped the intended product.

Political issues concern power, government and rights. Communication technology changes who can organize and who can watch whom. The same networks that let citizens organize protests let governments monitor citizens. Technology also shapes military power and international relations, from nuclear weapons during the Cold War to cyberattacks today. Decisions about regulating a technology are themselves political, and different countries have made different choices about data privacy, for example.

Ethical issues concern right and wrong. Some technologies create choices that did not exist before and so raise new ethical questions: whether and how to edit genes, who owns data collected about a person, whether machines should make decisions about hiring or policing, how to allocate scarce organs made transplantable by modern surgery. Technology does not answer these questions; it forces people to answer them.

Social issues concern how people live together: family, community, education, health and inequality. The automobile reshaped where people live, spreading suburbs far beyond the railroad and streetcar suburbs that came before it; television and then smartphones changed how families spend time. Access to technology is uneven, and the gap between those with and without access (often called the digital divide) can widen other inequalities.

Trade-offs are inevitable. The second statement says technologies inevitably involve trade-offs between costs and benefits. A trade-off means that to gain one thing you give up another. The word "inevitably" is the key claim: there is no technology with benefits and no costs. Costs include money, but also environmental harm, health risks, lost jobs, lost privacy and the other things that could have been done with the same resources (the opportunity cost). The costs and benefits often fall on different people, and at different times, which is why decisions about technology are contested.

Products and systems; intended and unintended consequences. A product is a single item (a pesticide, a car); a system is a network of parts working together (a highway network, an electric grid, a social media platform). Decisions about use have intended consequences, the results aimed for, and unintended consequences, results not aimed for. Two well-documented cases:

DDT. This insecticide was used widely from the 1940s. Its intended consequence was killing insects that carry disease and damage crops, and it helped reduce malaria in many regions. Unintended consequences emerged: DDT built up in food chains and harmed birds such as bald eagles, a problem publicized by Rachel Carson's Silent Spring in 1962; insects evolved resistance. The United States banned most uses in 1972. The 2001 Stockholm Convention restricted DDT worldwide but allowed its limited use against disease-carrying mosquitoes, recognizing that for some countries the malaria benefit still outweighs the cost. The case shows that the balance of a trade-off can differ by place.

The Green Revolution. From the 1960s, high-yielding varieties of wheat and rice, with irrigation and fertilizer, greatly increased harvests in Mexico, India and elsewhere; the plant scientist Norman Borlaug received the Nobel Peace Prize in 1970 for this work. Intended consequence: more food. Unintended consequences included greater use of water and fertilizer, runoff, and debates about whether larger farmers benefited more than small ones. People still disagree about how to weigh these.

A fully worked model. A hypothetical school district of 8,000 students decides to give every student a laptop. Benefits: access to information, practice in digital skills, easier assignment submission. Costs: purchase and repair budgets (money taken from other uses such as staff), screen time, privacy of student data. Economic issue: cost and whether it narrows skill gaps that affect future jobs. Political issue: the school board must justify the spending to voters. Ethical issue: what data the software collects and who can see it. Social issue: students without home internet may fall behind, so the district adds hotspots. Intended consequence: better access. A possible unintended consequence: more distraction in class, which the district might address with rules. The model shows that listing costs and benefits, naming who bears each, and planning for unintended consequences is the method; the laptop is neither simply good nor simply bad.

The misconception. Students often assume technology is neutral and only its users are good or bad, or the opposite, that a technology determines its effects. Both miss the standard's point. Design choices shape what a technology makes easy, and use choices shape what it actually does. Trade-offs are made twice: by those who develop, and by those who use.

Worked example 1 — sort by arena: The automobile. Economic: created an industry that employed many workers, including in Ohio, and lowered transportation costs. Political: governments built highways and set safety and emission rules. Ethical: who is responsible when a crash kills someone, and how to weigh convenience against pollution that harms people who do not drive. Social: suburbs grew and walking neighborhoods changed. Sorting into the four arenas named by the standard shows that one technology influences all four at once.

Worked example 2 — a trade-off that differs by place: DDT's trade-off in the United States in 1972 weighed harm to wildlife against crop and household uses for which alternatives existed, so a ban made sense to regulators. In a country where malaria killed many people each year, the same chemical sprayed inside homes could save lives, so the Stockholm Convention of 2001 kept an exception for disease control. The costs were similar; the benefits differed, so the decision differed. A trade-off is judged in context.

Worked example 3 — intended and unintended consequences of a system: Nuclear power plants are a system for generating electricity. Intended: large amounts of electricity with very low carbon emissions during operation. Unintended or risked: long-lived radioactive waste that must be stored, and the possibility of accidents, as at Chernobyl in 1986 and Fukushima in 2011. Supporters and critics weigh these differently; a fair analysis states both the benefit and the costs, and notes that the decision involves a value judgment about risk.

Trade-off ledger: Choose one technology (a product or a system). From sources you read, fill in a ledger: the intended purpose; two benefits and who receives them; two costs and who bears them; one unintended consequence; and one influence in each of the four arenas (economic, political, ethical, social). Note any entry you inferred rather than found.

Independent performance: Write a one-page recommendation to a decision-maker (a city council, school board, company or national government) about whether and how to use your technology. Success criteria: you distinguish development from use; you address economic, political, ethical and social issues; you state the trade-off explicitly, including who gains and who pays; you identify at least one intended and one unintended consequence and propose a way to reduce the harmful one; and you acknowledge a reasonable view that weighs the trade-off differently.
