Psychological Research: Crash Course Psychology #2

What does 'Hindsight Bias' refer to?

• Believing one knew the outcome of an event after it has happened

• The skill of learning from past mistakes to improve future outcomes

• The ability to predict future events accurately

• The tendency to ignore evidence that disproves one's beliefs

Why is replication crucial in psychological research?

• To verify the reliability and validity of findings across different contexts

• To make the research process longer and more complex

• To increase the difficulty of disproving a hypothesis

• To ensure that the results are due to chance

What is the main limitation of case studies in psychology?

• They are too easy to conduct and thus often lack depth

• They always require a large sample size to be valid

• They cannot be replicated, which may lead to over-generalizations

• They provide too much data to analyze effectively

What does 'correlation does not imply causation' mean?

• Causation can be easily determined by identifying correlations

• Correlations are irrelevant in psychological research

• Correlated events always have a direct cause-and-effect relationship

• Two events occurring together does not mean one caused the other

Why is random assignment important in experiments?

• It minimizes differences between groups to isolate the effect of the independent variable

• It guarantees that the results will support the hypothesis

• It ensures that the experiment can be conducted more quickly

• It allows researchers to choose which participants go into which group
