I hesitate to say what I\u2019m going to say because later I\u2019m going to say, \u201cDID I SAY THAT?\u201d But here goes. The coronavirus crisis has taught me one thing. Not that self-quarantine can be a painful experience. Not that our healthcare workers are among the most selfless in the world. And not that China can\u2019t be trusted, because I already had that sneaky suspicion. What it taught me, in the words of my father, is \u201cYou can\u2019t always believe what you read.\u201d Throughout this crisis, I\u2019ve often scratched my head in bewilderment and befuddlement and asked, \u201cCan I really believe that?\u201d I read the FDA said there\u2019s no evidence that groceries can transmit the virus, and then I read that gloves don\u2019t help in the supermarket and that the New York Public Library may quarantine books so they don\u2019t spread germs. (So groceries are OK, but books can kill?) I also read the virus is not transmitted through sex, and that it can live up to three days on metal and plastic but only 24 hours on cardboard. I\u2019ve seen interviews with more experts than at a National Institutes of Health happy hour, and I came away thinking, \u201cThat person doesn\u2019t know what the #%*@#$ he\u2019s talking about.\u201d I\u2019ve heard one expert say one thing and another expert say another. It reminds me of a civil lawsuit, where one expert gets on the witness stand and you think, \u201cHeck, she really knows what she\u2019s talking about.\u201d Then, another expert gets on the witness stand and says the exact opposite, and you ask yourself, \u201cWhat is truth?\u201d \u2014 to quote Pontius Pilate. Experts have been disagreeing ever since they told us masks wouldn\u2019t help and might harm us because special skills were required to put them on. If face masks don\u2019t work, then why were members of the House of Representatives wearing the super deluxe models \u2014 not masks made in China \u2014 while they debated the relief package? Gandhi put it best: \u201cThe expert knows more and more about less and less until he knows everything about nothing.\u201d The same is true of politicians, but politicians do it for self-promotion and self-preservation. Experts do it because a reporter puts a microphone in front of them, and they feel compelled to say something, anything, to convince us they know what they\u2019re talking about. \u201cEven when experts all agree, they may well all be mistaken,\u201d said Bertrand Russell, himself a self-proclaimed expert on the existence of God. So what should we believe? I put all the headlines and expert opinions together and came away scratching my head, wondering whether masks work or don\u2019t work, whether I can catch the virus from touching my mail, whether it will be worse in the autumn, whether it began in a Chinese wet market, laboratory or fried pork dumpling. Then, I turned to celebrities for guidance. Lady Gaga wants us to reach into our pockets and give our grocery money to the World Health Organization, while Chelsea Handler wants to lift our spirits by posting nude photos of herself in the bathtub. George Burns said, \u201cToo bad that all the people who know how to run the country are busy driving taxicabs and cutting hair.\u201d He should have added, \u201cand taking nude photos of themselves to put on the Internet.\u201d I\u2019m also reluctant to believe what newspaper columnists say ... especially this one. Just because someone has a column doesn\u2019t mean he knows what he\u2019s talking about. Always remember that most columnists have no other claim to credibility than a bachelor\u2019s degree in English literature. Which leads me to Edgar Allan Poe. In one of Poe\u2019s stories, the head of a mental institution tells his prot\u00e9g\u00e9e: \u201cYou are young, my friend, but the time will arrive when you will learn to judge for yourself what is going on in the world, without trusting the gossip of others. Believe nothing you hear, and only half of what you see.\u201d So instead of this column, you should be reading Poe. Did I really say that? Joe Pisani can be reached at email@example.com.
