blind (one) with science
To use technical terms or scientific jargon that the listener does not understand.
A good word, but perhaps a bit slangy. "Con" is also good. And also a slangy word.I think the verb you need is "bamboozle"
I understood "This person" who is trying to force his idea is not the IT manager, but the person making the pitch. But re-reading it, I see it could be read both ways. We probably need to have Nagomi clarify this.The thread title has "right idea", but in post #3 I see "his idea is critically wrong". So I haven't understood whether the IT manager's information is good or not. Perhaps his information is correct but his advice is bad? Nagomi also tells us that the IT manager is deliberately trying to misinform the others, but why is he doing that?
In fact, I'm still confused.
