Arrested Theory Development: The Misguided Distinction Between Exploratory and Confirmatory Research.

Area of Science:

• Psychology
• Philosophy of Science

Background:

• Scientific progress relies on identifying and correcting theoretical flaws.
• Effective theories are 'hard to vary,' maintaining explanatory power and consistency.
• Current replicability issues in psychology may stem from theoretical flexibility.

Purpose of the Study:

• To propose that theory flexibility, not just research methodology, underlies psychology's replicability crisis.
• To critique common methods-focused solutions for their ineffectiveness against theory flexibility.
• To advocate for theory criticism as a means to enhance scientific replicability.

Main Methods:

• Conceptual analysis of scientific progress and theory characteristics.
• Critique of existing methods-oriented approaches to replicability.
• Argument for prioritizing theory criticism in scientific practice.

Main Results:

• An abundance of flexible theories, rather than a lack of distinction between exploratory and confirmatory research, is identified as the primary cause of replicability problems.
• Popular methods-based solutions are shown to be insufficient for addressing the core issue of theoretical flexibility.
• Theory criticism by argument is proposed as a more effective strategy.

Conclusions:

• The flexibility of psychological theories is a significant barrier to scientific replicability.
• Addressing the replicability crisis requires a shift from methods-focused solutions to rigorous theory criticism.
• Emphasizing argumentative theory critique can foster more robust and reproducible scientific findings.
