English has words that are both connotative and denotative for “they think X” where X is false. The denotative verbs are simply “misbelieve” or “misthink” if you know it is false. The connotative form which immediately comes to mind is the various forms of “notion”. Its primary use case is to indicate that the thing it refers to is likely false and has no connection to reality.
