Rigidity
Preserving an angle after it has ceased to serve the purpose.
Habitual unwillingness to revise a view or method when relevant reasons call for reconsideration.
Imagine this: A worker keeps trying to push a long beam through a narrow doorway without turning it.

How the pattern works
The beam can fit through the opening, but not in the position its carrier insists on preserving. Rigidity attaches to the familiar view or method so tightly that relevant reasons for revision receive little practical weight. The means acquire the authority of the purpose.
A procedure can embody hard-won knowledge, and a considered conviction should not be changed by every objection. The rigid pattern refuses the examination that could distinguish useful continuity from an obsolete step. “This is how it is done” becomes the answer even when the person can no longer explain what the method accomplishes.
What it costs the work
A customer may be made to satisfy a form that no longer fits the service, a colleague may have to repeat a known failure or a useful change may remain blocked by the history of the existing arrangement. Effort increases without improving the outcome because every attempt preserves the feature that needs reconsideration.
A distinction worth keeping
Holding an ethical boundary is not Rigidity merely because someone wants an exception. Constancy keeps a defensible purpose answerable through time; Rigidity resists a relevant revision of view or means. Complacency may see no need to look; Arrogance may dismiss the person offering the reason. These can accompany the same stubborn decision without becoming identical dispositions.
What a useful response can change
The purpose of the method can be stated independently of the method itself. That makes it possible to ask whether another angle would preserve what actually matters.
An alternative can be assessed against the same relevant criteria as the established arrangement. Novelty is not a sufficient argument, but age is not a permanent exemption.
A bounded trial can turn a contest of loyalties into an examination of results. A necessary ethical or safety limit remains part of that examination rather than something the trial silently suspends.
Questions for reflection
- What is the reason for keeping this feature unchanged?
- Which part of the purpose would a different method genuinely threaten?
Other perspectives
Whosoever is found variable, and changeth manifestly without manifest cause, giveth suspicion of corruption; therefore, always when thou changest thine opinion or course, profess it plainly, and declare it, together with the reasons that move thee to change, and do not think to steal it.

Bacon advises making a change of course and its reasons explicit. Explained revision allows continuity of trust without requiring the same answer after the evidence changes.
Alertness, flexibility, curiosity are the essentials; dogmatism, rigidity, prejudice, caprice, arising from routine, passion, and flippancy are fatal.
John Dewey · How We Think · Read the source
Dewey contrasts flexible inquiry with rigidity and caprice. Responsiveness to reasons differs both from repeating the same attempt and from changing merely for novelty.
