Rigorous

/ˈrɪɡ.ər.əs/ adjective

Definition

Rigorous means very thorough, careful, and strict, often with high standards that are hard to meet. A rigorous test or process leaves little room for mistakes or laziness.

Etymology

From Middle English *rigorous*, from Old French *rigoreus*, from Latin *rigorosus* “stiff, harsh,” from *rigor* “stiffness, severity.” The original sense was literally about physical stiffness and hardness.

Kelly Says

Rigorous once described how stiff something felt, and it still carries that hardness into ideas and rules. A “rigorous experiment” is one where the rules are so tight that sloppy thinking can’t wiggle through.

Ethical Language Guidance

Gender History

Academic and professional “rigor” has historically been defined within male‑dominated institutions, sometimes devaluing methods and topics associated with women (e.g., qualitative research, care work, domestic labor). This has influenced what is seen as serious or legitimate knowledge.

Inclusive Usage

Apply “rigorous” consistently across fields and methods, not only to traditionally male‑dominated disciplines. Avoid using it to dismiss work on gender, care, or other marginalized topics as inherently less serious.

Inclusive Alternatives

["thorough","methodical","strict","exacting"]

Empowerment Note

Women scholars have led rigorous work across disciplines, including in areas long dismissed as “soft” or feminine, reshaping standards of evidence and methodology.
