Inconvenience and generalization in building a better psychology: Commentary on Sherman (2025)

Area of Science:

• Psychology
• Cognitive Science

Background:

• Convenience sampling is frequently used in research.
• Sherman's (2025) defense of convenience sampling may inadvertently downplay broad generalization.

Purpose of the Study:

• To supplement Sherman's defense of convenience sampling.
• To emphasize the critical role of broad generalization and diverse samples in research.
• To clarify the importance of explicitly stating generalizability.

Main Methods:

• Commentary and theoretical review.
• Analysis of the implications of sampling methods on research findings.
• Discussion of strategies for achieving broad generalization.

Main Results:

• Broad generalization is essential for capturing the full spectrum of human cognitive variation.
• Explicitly stating the generalizability of findings is vital for accurate interpretation and application.
• Several practical methods can enhance broad generalization in research.

Conclusions:

• While convenience sampling has its place, it should not overshadow the necessity of broad generalization.
• Achieving broad generalization requires diverse samples and methodologies, including developmental, comparative, and cross-cultural approaches.
• Clear communication of generalizability is key for translating research into practice.
