Evaluation criteria
What we analyse — and why it matters
Every analysis is grounded in four dimensions of research quality used by peer reviewers worldwide.
Internal Validity
Evaluates study design, control conditions, and confounding variables. Determines how confidently you can attribute outcomes to the studied cause.
Reliability
Examines sample size, measurement consistency, and replicability — a cornerstone of trustworthy, repeatable science.
Statistical Reporting
Checks for appropriate tests, p-values, confidence intervals, and effect sizes. Weak reporting is the most common source of misleading research.
Bias & Limitations
Identifies selection bias and generalisability issues, and assesses whether authors honestly acknowledge their own study's limitations.
