Ethical Considerations

Research Methods

Interpreting Data

In the past, researchers performed all kinds of questionable experiments in the name of science. For example, in one famous experiment, psychologist Stanley Milgram led his subjects to believe that they were giving painful electric shocks to other people. Many people consider this experiment unethical because it caused the subjects emotional discomfort. Today, researchers must abide by basic ethical norms when conducting research. Most important, they must consider whether they might harm their human or animal subjects while doing research.

Research with Human Subjects

Researchers must get informed consent from their subjects before beginning research. Informed consent means that subjects must know enough about the research to decide whether to participate, and they must agree to participate voluntarily. Furthermore, researchers have an ethical obligation to prevent physical and mental harm to their subjects. If there is any risk of harm, they must warn subjects in advance. Researchers also must allow subjects to withdraw from a study at any time if they wish to stop participating. Finally, researchers have an obligation to protect the anonymity of their subjects.

Some psychological research cannot be done when subjects are fully informed about the purpose of the research, because people sometimes behave differently when under observation. To study people’s normal behavior, researchers sometimes have to deceive subjects. Deception is considered ethical only if:

  • The study will give researchers some valuable insight
  • It would be impossible to do the study without deception
  • Subjects can learn the truth about the study’s purpose and methods afterward

Research with Animal Subjects

Although most psychological research involves human subjects, some psychologists study animal subjects instead of or in addition to humans. Research with animal subjects has helped psychologists do the following:

  • Learn facts about animal species
  • Find ways to solve human problems
  • Study issues that can’t be studied using human subjects for practical or ethical reasons
  • Refine theories about human behavior
  • Improve human welfare

Many people question the ethics of animal research because it can involve procedures such as deprivation, pain, surgery, and euthanasia. Psychologists have ethical obligations to treat animal subjects humanely and to do research on animals only when the benefits of the research are clear.

People who are against animal research maintain three arguments:

  • Animals should have the same rights as humans.
  • Society should enact safeguards to protect the safety and welfare of animals.
  • Researchers should not put the well-being of humans above the well-being of animals.
