It really depends though. There are many fundamentalists who honestly believe what they believe and they are not being at all intellectually dishonest when they say what they believe. They may be very very wrong, but they believe it.
Again intellectual honesty does not require a person to be right. Only that the person sincerely believes he/she is right in his/her belief.
But those who promote concepts/situations/events in ways that they know in their hearts and minds are not the whole story or the actual story at all are being intellectually dishonest. when they do that.
Example:
The MSM/'legacy media' of course had to see the signs that Joe Biden was suffering from advanced dementia and there was no way he was actually doing the job of President of the United States. But they continued to defend and protect him and refused to report what they knew. And then there was that terrible debate between Trump and Biden that I am convinced set Biden up so they could pretend for the first time to see how mentally damaged he was.
And that set the stage for the Democrat Party to remove him as candidate for a second presidential term.
All that was blatant intellectual dishonesty on the part of those who desperately wanted to believe but you know they really didn't.
Intellectual honesty requires that you seek the truth, and know the truth, as well as speak it. If you honestly believe something that isn't true, you are not being intellectually honest at all because you have no idea of the truth of your beliefs.

Are You Intellectually Honest?
Do you know propaganda when you see it? Do you use logical fallacies without realizing it? Being intellectually honest is more necessary now than ever.
Joe Biden does not have "advanced dementia". That's a complete lie. He older and his stamina is an issue, leading to confusion, but his does not have "dementia" and it is DISHONEST of you to say it, both factually and intellectually.
