That is an awful sentiment, and I find myself in violent disagreement with you.
A good number of my enjoyable interviews have been with candidates who clearly knew more than I did, and could expand from an interesting detail to a short ex-tempore lecture on the topic. I cherish each of those.
An interview where I, as an interviewer, learn something is a fine thing indeed.
If the interviewer is in a position where he/she seems willing to listen and learn, then by all means impress. However, correcting an interviewer is always a dangerous gamble, and it is downright foolish to keep arguing with him or her when he/she doesn't agree with you.
Any company who maintains that their interviewers are always right is telegraphing that they treat their workforce as mindless cogs in a machine.
Every time I encounter a candidate who thinks differently than I do, I treat him or her as a potential source of inspiration. Occasionally I learn something, and occasionally they do.
