Question: Imagine you are planning to replicate a controversial psychological finding. Applying the lessons of the Many Labs Replication Project, which specific design decision should you make regarding your sample size, and why is this decision necessary?
Sample answer: I should design the study to have a much larger sample size than the original study while keeping the materials and procedures identical. This is necessary because small sample sizes can lead to unreliable findings, and a larger sample provides a more rigorous test of the effect's reliability.
Key points:
- Specify using a much larger sample size.
- Maintain identical or nearly identical materials and procedures.
- Explain that larger sample sizes are necessary to prevent unreliable results and provide a rigorous test of the finding.
Rubric: The response must specify choosing a larger sample size and explain that this is necessary to ensure reliability and correct potential errors associated with small sample sizes.

In the Many Labs Replication Project, an international team of researchers successfully replicated the original finding that handwashing reduced the perceived severity of moral transgressions.
In the Many Labs Replication Project, an international team of researchers attempted to replicate the finding that handwashing reduces the perceived severity of moral transgressions. When they were unable to reproduce the results with larger samples, how did this outcome demonstrate the self-correcting nature of science?
A psychology student is examining how the scientific community handled the 'handwashing and morality' finding. Arrange the following events in the chronological order that best illustrates the self-correcting nature of science as seen in the Many Labs Replication Project.
The Many Labs Replication Project provided a critical re-evaluation of the 'handwashing and moral transgressions' study. Match each analytical component of this project to its specific functional role in the process of scientific revision.
In the Many Labs Replication Project, which 'established finding' did an international team of researchers attempt to replicate to test its reliability?
In the Many Labs Replication Project, the inability to replicate the original 'handwashing' results with larger samples is interpreted as a success of the scientific method because it allows researchers to identify and correct findings that are likely unreliable.
When comparing the conflicting evidence between studies, the Many Labs Replication Project's failure to reproduce the 'handwashing' effect using significantly larger samples leads to the scientific judgment that the original study's results were _____.
