Exposing and overcoming the fixed-effect fallacy through crowd science.

Area of Science:

• Behavioral and Social Sciences
• Psychology
• Reproducibility in Science

Background:

• The generalizability crisis in science refers to the difficulty in replicating research findings across different contexts.
• Existing research often lacks diverse approaches, limiting the scope of conclusions.

Purpose of the Study:

• To propose a crowdsourced approach to address the generalizability crisis in scientific research.
• To outline methods for synthesizing findings from heterogeneous research studies.

Main Methods:

• Organizing independent groups of scientists to investigate the same research questions.
• Employing aggregation techniques, such as meta-analysis of effect sizes.
• Utilizing parsing methods to identify moderators explaining result variability.

Main Results:

• Crowdsourcing research can yield more robust and generalizable findings.
• Aggregation and parsing are effective strategies for integrating diverse study outcomes.
• Identifying moderators enhances the theoretical understanding of research variability.

Conclusions:

• A crowdsourced, multi-pronged approach is a viable solution to the generalizability crisis.
• Systematic analysis of heterogeneous results is key to advancing scientific knowledge.
