Testing Competing Theories with Hypotheses
Among the strongest hypotheses are those formulated to distinguish between competing scientific theories. In this scenario, researchers identify two theories that offer conflicting explanations for the same phenomenon. They then design a study and derive a single hypothesis where each theory implies a mutually exclusive outcome. Because the predictions are opposite, observing the study's results will confirm one theory's prediction while simultaneously disconfirming the alternative.

A researcher is investigating the connection between the amount of time spent on a social media app and users' self-reported levels of happiness. The researcher starts with the general idea that excessive social media use might negatively affect well-being.

Which of the following accurately describes one of the main strategies researchers use to derive a hypothesis from a scientific theory?
A researcher notices that an established theory of social conformity describes an internal cognitive mechanism that has never been directly measured in any published study. The researcher then creates a hypothesis predicting specific observable outcomes if that mechanism operates as the theory claims. This approach illustrates deriving a hypothesis by identifying an untested component within a theory and designing an empirical test for it.

What is the primary advantage of formulating a single hypothesis to distinguish between two competing scientific theories with mutually exclusive outcomes?
A researcher notices that Theory A predicts participants will perform better on a memory task under noisy conditions, while Theory B predicts they will perform worse. She designs a single experiment to test both predictions at once. If the results show that participants performed worse under noisy conditions, this outcome would provide evidence supporting Theory B while simultaneously counting as evidence against Theory A.
