Regardless of reality, perception of reality is more important for this. The boss can think the worker is wrong, and can react with a

> That's stupid, it won't work due to X, we're going with Y

or a

> Thanks for the feedback, but this time we're choosing Y due to X.

One is going to leave the worker happier than the other and feeling safer despite the boss thinking the worker is wrong. Unless you can measure the counter-factual (often not) you will only guess as to which was better.

The latter is really just a more polite version of the former. I think the trust inspiring response would be,

What are your concerns with solution A such that you think solution Y is better? Help me understand so I can explain what you're missing. Or, so I can see what I'm missing.
