This is a key takeaway that, I suspect, everyone who has ever been interviewed, covered, or quoted in the press feels.
Every time you see a story in the general media that grossly misrepresents a subject you know well, remember that feeling. Because for every other topic covered, I guarantee there is a domain expert feeling as you did.
I’m three for three in terms of regretting journo contact. Whether it was the local rag or a national broadsheet; misquotation, glib misrepresentation and sheer fabrication are inevitable results.
Corollary: reserve your greatest mistrust for anyone that openly and actively courts the media. They are well aware of the outcomes and are manipulating the game. This includes your in-house PR team and most elected officials, including the ones you voted for.
