Arrogance
Treating technical fluency or privileged access as authority beyond its grounds and discounting correction or others' standing.
He can explain the system. Apparently he can also explain away everyone it affects.
An inflated sense of one's importance or judgment that discounts correction and other people's standing.
Genuine expertise and confident warranted claims differ.
How it takes hold
Technical knowledge answers some questions very well. Arrogance lets that achievement expand into a general entitlement to decide whose concerns count. The person explaining the system begins to regard an affected person's knowledge as an interruption.
The disposition inflates importance or judgment and discounts correction and other people's standing. Technical expertise can become its occasion, as can proud certainty that technical work has nothing to teach. Neither side acquires unlimited authority from being right about one thing.
Important facts are excluded because they arrive without the preferred status. An impressive explanation can coexist with a decision poorly fitted to the people it affects.
Finding the distinction
Illustrative situation: a user reports a failure outside the developer's demonstration.
Too arrogant: technical standing determines whether the report matters.
Fitting: report and explanation are examined for relevant evidence.
Overcorrection: demonstrated expertise receives no authority.
Vanity seeks admiration; arrogance may disregard the audience. Contempt denies basic consideration, while arrogance can discount a judgment without explicitly denying worth.
Real expertise deserves appropriate weight. Fair consideration does not require treating every opinion as equally informed.
Counterfeit of Discernment: Technical confidence is used to dismiss a user's relevant report without examination. Genuine Discernment weighs evidence within and beyond one's own expertise.
A response that restores something
A constructive discussion identifies which question each person is well placed to answer. Design and lived consequences can require different evidence.
A correction can be evaluated without demanding that its source first match the evaluator's credentials.
Humility retains competence within its scope. Listening gives expertise a fuller situation to address.

the teacher has usually more to learn than to teach

Dewey identifies something the learner may reveal to the expert, not an abolition of expertise.
their certainty is the same thing as absolute certainty
John Stuart Mill · On Liberty
Mill questions inflation from confidence to infallibility, the move through which correction loses its hearing.
