What is the Leiden Manifesto?
The Leiden Manifesto for research metrics is a set of ten principles for using quantitative research metrics responsibly — to support, not replace, expert judgement.
The Leiden Manifesto for research metrics, published in Nature in 2015, is a set of ten principles for the responsible use of quantitative indicators in research assessment. Its core idea is that metrics should inform, not replace, expert judgement.
Among its principles: quantitative evaluation should support qualitative, expert assessment; measure performance against the mission of the group; account for differences between fields; keep data collection and analysis transparent; and recognise that indicators can be gamed and have systemic effects.
Why it matters for your CV
Like DORA, the Leiden Manifesto encourages reading metrics in context and not reducing a researcher to a single number. If you present metrics on a CV, choose field-normalized indicators, give context, and let your actual contributions lead.

Frequently asked questions
How is the Leiden Manifesto different from DORA?
Both promote responsible research assessment. DORA focuses on not misusing journal-based metrics (like the Impact Factor) for individual assessment; the Leiden Manifesto gives ten broader principles for using any quantitative metric responsibly alongside expert judgement.
