Abandoning a Scientific Theory
Although researchers attempt to modify theories to address contradictory evidence, they cannot ignore repeated disconfirmations indefinitely. If scientists are consistently unable to improve their research designs or adjust their theories to account for ongoing failures in prediction, they must eventually abandon the weakened theories and replace them with more successful models.

Abandoning a Scientific Theory
Example of Modifying a Theory
What is a common practice among researchers when a hypothesis is disconfirmed by new evidence, rather than immediately discarding the original theory?
When a hypothesis is disconfirmed by new observations, it is standard scientific practice to immediately discard the underlying theory entirely.
A researcher finds that their data contradicts their theoretical predictions. Match each research scenario with the appropriate strategy for modifying the theory rather than discarding it.
A social psychologist finds that a theory predicting 'people will help less when in a group' (the Bystander Effect) fails to hold true in high-danger emergencies. Arrange the following steps in the logical order the researcher would take to modify the theory to account for this contradictory evidence.
A psychological theory states that 'Visual Feedback improves motor learning by allowing the brain to correct errors in real-time.' However, a new experiment finds that for tasks requiring extremely high speed, visual feedback actually hinders learning because the brain cannot process the images fast enough. Which of the following represents the most scientifically rigorous creation of a modified theoretical framework to account for this contradiction?
Match each term related to the scientific process of theory refinement with its corresponding definition based on how researchers handle disconfirmed hypotheses.
A researcher decides to modify a scientific theory rather than discard it after a hypothesis is disconfirmed. Arrange the steps of the modification process in the correct logical order.
In the scientific evaluation of a theory that has produced a disconfirmed hypothesis, a researcher who judges the core theory to be 'conditionally valid' rather than 'false' is choosing to refine the theory's _____.
If a researcher obtains contradictory evidence and adjusts their framework to state that a previously proposed cognitive effect only occurs under specific, limited circumstances, they are modifying the theory by adjusting its boundary conditions rather than discarding the theory entirely.
When evaluating a study with contradictory findings, a researcher decides not to discard the underlying theory but instead adjusts the framework to account for the fact that a necessary condition was not met in the sample. By doing so, the researcher is adapting the theory by addressing unmet _____.

What must researchers eventually do if they are consistently unable to improve their research designs or adjust their theories to account for ongoing failures in prediction?
When a psychological theory encounters contradictory evidence, it undergoes a process of evaluation. Arrange the steps of this process in the correct order, ending with the point at which the theory is discarded.
A psychological research team has modified the 'Social Presence Theory' four times to account for failed predictions. Despite these revisions and the use of the most rigorous experimental controls available, their latest study still results in data that significantly contradicts the theory. In this situation, the most scientifically appropriate next step is for the team to continue adjusting the theory's assumptions rather than abandoning it.
Analyze the following research scenarios and match each situation with the scientifically appropriate action based on the relationship between evidence, design, and theoretical stability.
If a scientific theory consistently fails to make accurate predictions, researchers are expected to continue modifying the theory indefinitely rather than eventually abandoning it.
In psychological research, when a scientific theory consistently fails to make accurate predictions despite researchers' efforts to modify the theory and improve their research designs, what is the most scientifically appropriate action, and why?
A researcher encounters contradictory evidence for their theory. Match each research situation to the scientifically appropriate next action, applying the principle that theories should be modified when possible but abandoned when modification is no longer viable.
Dr. Kim has conducted five increasingly well-controlled experiments testing her theory of attentional focus. Each experiment disconfirmed the theory's predictions. After every failure she revised the theory, but the next experiment still disconfirmed the revised version. Analyzing this pattern of persistent predictive failure despite multiple revisions, a peer reviewer concludes that the theory has become too _____ to be scientifically viable and should be replaced with a more successful model.
A scientist is deciding whether to abandon a psychological theory after receiving contradictory evidence. Arrange the following evaluative criteria in the order they should be applied — from the first consideration to the final justification — so that any decision to abandon the theory is scientifically warranted rather than premature.
A research team has iteratively modified a psychological theory multiple times to account for anomalous data; however, subsequent high-power experiments continue to produce results that contradict the theory's core predictions. In this scenario, the most scientifically sound evaluative action for the researchers to take is to _____ the theory in favor of a more empirically supported model.
According to the scientific process of evaluating and modifying theories, what must researchers eventually do if they are consistently unable to adjust their theories or improve their research designs to account for ongoing failures in prediction?
Using your understanding of how scientific theories are evaluated, explain why Dr. Evans cannot continue to modify this theory indefinitely and identify what action must ultimately be taken.
A research group has revised their hypothesis and experimental controls four times to resolve a discrepancy between their theory of memory consolidation and their experimental results, but the new predictions still fail. Apply the scientific principle of theory abandonment to determine what the research group should do next.
