I find people who get taken in tend to be those who don't engage much with the material reality. Upper management is a perfect example here. They tend to have a very tenuous understanding of how things are actually made, and then when the LLM tells them something that sounds plausible they have no way to test it. And in a sense the way they've been communicating before LLMs showed up isn't really dissimilar. They just tell each other stories that fit what they want to hear, and LLM speaks their language.
