I appreciate what you have written. It takes true strength of character to confess publicly. But we all share responsibility for these things. It is up to each of us to be more questioning and less credulous/gullible regarding the things we read and hear. We say in jest "it's on the internet, so it must be true" but consider how often we subconsciously make that exact assumption.
For everyone reading this - consider news stories about areas in which you have some expertise. Aren't they often wrong or misleading in critical ways? I would say I have the education and experience to be an expert in only three things - submarines, nuclear power plants and certain areas of the law. When I read articles about these, I constantly notice things that are incorrect or incomplete in ways that may inflame or incite. I saw this quite a bit in the coverage of the 2011 Fukishima incident.
This phenomenon doesn't stem from malice by journalists. Rather, it is a reflection that they are experts in journalism, not necessarily the things they are writing about. It takes years to truly understand an esoteric field like nuclear power (or, today, epidemiology and virology), but they have a deadline to publish. And, to be honest, boring doesn't sell newspapers. With the rise of the internet, the problem is only exacerbated. People who have no knowledge of or commitment to journalistic ethical standards are able to publish anything and everything they want without any gatekeeping or editorial function. They may be experts, but probably not.
So what can we do? Simply keep this factor in mind. When reading, ask "How can they know that?", "What have they not told me?" or "Do they speak in tones of absolute truth when that is not warranted?" and, most of all, "Does this make sense?" You don't have to be an expert to detect that the author may be overstepping the bounds of his or her actual knowledge. And one good thing about the internet is that you easily can do your own research when something you have read sounds, as Aerides notes, "too terrible to be true".
