Talkative Women as an Example of Confirmation Bias

Which of the following best describes the cognitive tendency known as confirmation bias?

Match each research behavior with the component of confirmation bias it illustrates, based on how researchers process information.

A psychologist testing a new treatment for depression only records the progress of participants who report feeling better, while dismissing those who show no improvement as 'not having followed the protocol.' This researcher is demonstrating confirmation bias by selectively attending to supportive data and disregarding contradictory evidence.

A psychological researcher is conducting a systematic review of the relationship between social media use and self-esteem. Arrange the steps below to illustrate how the researcher’s analytical process would logically progress if it were driven by confirmation bias.

When evaluating the scientific validity of a researcher's conclusion, a peer reviewer notes that the investigator only documented observations that aligned with their initial predictions while dismissing all contradictory data as 'procedural errors.' This systematic failure to objectively consider all evidence indicates that the study's findings are undermined by _____ bias.

According to the definition of confirmation bias, what typically happens to evidence that contradicts a person's pre-existing intuitive beliefs?

Confirmation bias reinforces incorrect assumptions because people tend to focus on and remember evidence that supports their existing beliefs while overlooking evidence that would challenge those beliefs.

Match each research or everyday scenario to the specific component of confirmation bias it best illustrates.

Analyze how confirmation bias operates as a cognitive heuristic during the data analysis phase of a research project. In your response, explain how the tendency to selectively focus on validating cases and disregard contradicting cases leads researchers to reinforce incorrect assumptions.

Evaluate the psychologist's handling of the study outcomes. Diagnose the specific cognitive tendency demonstrated in his actions, justify why this behavior constitutes a threat to scientific inquiry based on the provided definition of this tendency, and decide what corrective actions he should take to ensure a valid scientific conclusion.

Define confirmation bias and state the primary consequence this cognitive shortcut has on an individual's pre-existing assumptions when they encounter contradicting evidence.
