Is it dishonest to let someone leave a conversation with a false conclusion?

Hello,

What is a word for allowing someone to arrive at the wrong conclusion?

Also, is doing so dishonest?

I think everyone would agree that knowingly communicating something false (ie lying) is a form of dishonesty. However, if one party in a conversation has not lied but clearly understands that another party in the conversation has come to an incorrect conclusion (for whatever reason), is it dishonest for the first party to leave it alone?

I have been comparing some words related to this topic and their definitions. For example:

Equivocate:
• use ambiguous language so as to conceal the truth or avoid committing oneself
• use ambiguous or unclear expressions, usually to avoid commitment or in order to mislead

Prevaricate:
• speak or act in an evasive way
• to speak falsely or misleadingly;
• deliberately misstate or create an incorrect impression; lie.

Obfuscate:
• render obscure, unclear, or unintelligible
• to confuse, bewilder, or stupefy

Tergiversate (ter-JIV-er-sate):
• make conflicting or evasive statements; equivocate
• to change repeatedly one's attitude or opinions with respect to a cause, subject, etc

Lie:
• intentionally communicate a false statement
• to speak falsely or utter untruth knowingly, as with intent to deceive.

There are others of course but it seems that each of them is located somewhere on one or more scales or spectra with the following extremes (which I'm sure contain some overlap or redundancy):

Passive — — — — — — — — — — Proactive
Unintentional — — — — — — — — — — Intentional
Inaction — — — — — — — — — — Action

Of the above words and others I found, it seems that "equivocate" is the one furthest from actually lying but the definition still implies some degree of proactive intent and action to mislead. The concept I'm describing and the word I'm looking for (if it exists), would reside at the far left of the above scales.

In other words, nothing was said or done by the communicator — and perhaps there was not even any intent — to deceive or mislead. However, there is a recognition that, unless corrected, the "communicatee" will leave with a meaning or understanding which is inaccurate or false.

Thanks
