How should we address non-reproducibility?

Area of Science:

• Experimental biology
• Comparative physiology

Background:

• Inter-experimental variability is a major obstacle to reproducibility in biological research.
• Inconsistent reporting of experimental details, despite guidelines like ARRIVE and MDAR, contributes significantly to non-reproducibility.
• Numerous factors, including reagent variations, equipment calibration, and environmental conditions, contribute to this variability.

Purpose of the Study:

• To highlight the critical need for comprehensive and standardized reporting practices in experimental biology.
• To emphasize the role of insufficient methods reporting in hindering scientific reproducibility.
• To advocate for a multifaceted approach to improve the reliability and credibility of research findings.

Main Methods:

• Review of existing guidelines (e.g., ARRIVE, MDAR) and their limitations in practice.
• Analysis of factors contributing to inter-experimental variability.
• Discussion of innovative approaches like experimental heterogenization and open science initiatives.

Main Results:

• Insufficient reporting of materials and methods is a substantial contributor to non-reproducibility.
• Current reporting practices often lack the necessary detail and consistency.
• Existing guidelines are not always rigorously enforced.

Conclusions:

• Stricter enforcement of reporting standards by publishers, editors, and reviewers is essential.
• Authors and researchers must prioritize detailed and consistent reporting of experimental methods.
• A cultural shift valuing reproducibility, alongside initiatives like experimental heterogenization and open science, is crucial for advancing reliable biological research.
