Maybe a large part of what we are really facing here is that the Internet has made everyone an "armchair expert."

As a super simple example, consider an item from the mental health field. "Narcissism" is definitely real but from the clinical perspective the actual mental health disorder is quite rare, but if you walk around on the street it seems like every person you meet "knows at least 3-4 Narcissists."

As to vaccine passports, most people don't even know that you had to have them for international travel back in the 1950's and 1960's. I still have my old yellow 1960's WHO vaccine book... we could go nowhere outside Europe without proof of Yellow Fever, Malaria, Swamp Fever, Typhoid and other records of vaccinations. Old applied idea, recycled. What's changed isn't the idea, but our perception that having to prove our status is no longer "a matter of health safety," but instead "an infringement on our RIGHTS."

As always, there's a fine line between healthy suspicion and outright paranoia.
