Fake news, as a concept, has been around for a long time. But we used to call it something else: propaganda.

That our president was able to harness the term “fake news” and ride its wave, is disconcerting to people in the business of reporting news, because it is so often an attack on media outlets that pride themselves on unbiased reporting.

But the president’s attacks are not completely groundless, which is why they resonate with so many Americans.

Journalism schools have evolved over the past generation, in an attempt to equip young people with the tools they need to succeed.

And success for most journalists means ferreting out the truth in each assignment they take on, and then reporting their findings.

The internet, more monstrous a media than anyone could have imagined, makes that difficult because it has created what is now called “the attention economy.”

There is much too much information available to news consumers, and so the behemoths of media, which are no longer the national press, are continuously researching ways to capture and keep your attention for as long as possible – and this is no exaggeration – that time is measured in seconds, not minutes.

And so, most of the information these days is no longer designed to inform you, but to get and keep your attention as long as possible, and if you started reading this editorial online, chances are good that you didn’t make it this far.

As some might say: Sad.

But there is good news in the chaos being sown by the purveyors of what President Reagan called misinformation.

Any good journalist will admit to being equipped with a healthy bulls**t detector.

Credible journalists know that they need to have sources who are reliable, and then they need to get a second reliable source prior to reporting what might be a controversial story.

Readers, too, should always be skeptical of what is reported and be open to the possibility that the author has ulterior motives. Stay skeptical.

Our freedom depends on it.
