The Scientific Method Psychologists use the scientific method to conduct their research. The scientific method is a standardized way of making observations, gathering data, forming theories, testing predictions, and interpreting results. Researchers make observations in order to describe and measure behavior. After observing certain events repeatedly, researchers come up with a theory that explains these observations. A theory is an explanation that organizes separate pieces of information in a coherent way. Researchers generally develop a theory only after they have collected a lot of evidence and made sure their research results can be reproduced by others. Example: A psychologist observes that some college sophomores date a lot, while others do not. He observes that some sophomores have blond hair, while others have brown hair. He also observes that in most sophomore couples at least one person has brown hair. In addition, he notices that most of his brown-haired friends date regularly, but his blond friends don’t date

He then conducts an experiment to test his hypothesis. In his experiment, he has twenty people go to a party, ten with blond hair and ten with brown hair. He makes observations and gathers data by watching what happens at the party and counting how many people of each hair color actually make dates. If, contrary to his hypothesis, the blond-haired people make more dates, he’ll have to think about why this occurred and revise his theory and hypothesis. If the data he collects from further experiments still do not support the hypothesis, he’ll have to reject his theory....
