In 1966, Paul McCart­ney famous­ly sang of “all the lone­ly peo­ple,” won­der­ing aloud where they come from. Near­ly six decades lat­er, their num­bers seem only to have increased; as for their ori­gin, psy­chi­a­trist, psy­cho­an­a­lyst, and Zen priest Robert Waldinger has made it a long­time pro­fes­sion­al con­cern. “Start­ing in the nine­teen fifties, and going all the way through to today, we know that peo­ple have been less and less invest­ed in oth­er peo­ple,” he says in the Big Think video above. “In some stud­ies, as many as 60 per­cent of peo­ple will say that they feel lone­ly much of the time,” a feel­ing “per­va­sive across the world, across all age groups, all income groups, all demo­graph­ics.”

“Hav­ing an exten­sive net­work of friends is no guar­an­tee against lone­li­ness,” writes the late soci­ol­o­gist Ray Old­en­burg in The Great Good Place. “Nor does mem­ber­ship in vol­un­tary asso­ci­a­tions, the ‘instant com­mu­ni­ties’ of our mobile soci­ety, ensure against social iso­la­tion and atten­dant feel­ings of bore­dom and alien­ation. The net­work of friends has no uni­ty and no home base.” He names as a key fac­tor the dis­ap­pear­ance, espe­cial­ly in Amer­i­can life since World War II, of “con­ve­nient and open-end­ed social­iz­ing — places where indi­vid­u­als can go with­out aim or arrange­ment and be greet­ed by peo­ple who know them and know how to enjoy a lit­tle time off.”

Old­en­burg’s ele­gy for and defense of “cafés, cof­fee shops, com­mu­ni­ty cen­ters, gen­er­al stores, bars,” and oth­er engines of com­mu­ni­ty life, was pub­lished in 1989, well before the rise of social media — which Waldinger frames as the lat­est stage in a process that began with tele­vi­sion. As more Amer­i­can homes acquired sets of their own, “there was a decline in invest­ing in our com­mu­ni­ties. Peo­ple went out less, they joined clubs less often. They went to hous­es of wor­ship less often. They invit­ed peo­ple over less often.” Then, “the dig­i­tal rev­o­lu­tion gave us more and more screens to look at, and soft­ware that was designed specif­i­cal­ly to grab our atten­tion, hold our atten­tion, and there­fore keep it away from the peo­ple we care about.”

We also know, he con­tin­ues, that “peo­ple with strong social bonds are much less like­ly to die in any giv­en year than peo­ple with­out strong social bonds.” This is a cred­i­ble claim, giv­en that he hap­pens to direct the now 85-year-long Har­vard Study of Adult Devel­op­ment. In 2016, we fea­tured Waldinger’s TED Talk on some of its find­ings here on Open Cul­ture. Before that, we post­ed a PBS Brain­Craft video that con­sid­ers the Har­vard Study of Adult Devel­op­ment along with oth­er research on the con­tribut­ing fac­tors to hap­pi­ness, a body of work that, tak­en togeth­er, points to the impor­tance of love — which, even if it isn’t all you need, is cer­tain­ly some­thing you need. And thus one more Bea­t­les lyric con­tin­ues to res­onate.
