I grew up in the 1960s and 70s, at a time when fundamental physics was making huge dramatic progress and Western democracies were changing in equally dramatic ways, mostly for the better. It truly did seem that the Age of Aquarius was upon us, and that human societies were on a consistent route to progress, however uneven. By the late 1970s and early 1980s things had started to change, but that humanity and my chosen field of science were sooner or later moving forward still seemed self-evident.
By the late 1990s the situation started getting more disturbing. The likes of Newt Gingrich started taking over the Republican party, with a highly successful propaganda arm called Fox News running 24 hours a day, pushing lies about the Democrats, especially the Clintons (remember Whitewater?). For some mysterious reason, even the New York Times joined in. In theoretical physics, proponents of a failed theory dominated the subject, putting out endless propaganda to the public such as Michio Kaku’s Hyperspace.
Around this time I started spending a lot of time trying to understand how these things could be happening. If someone is saying obviously untrue things, logically there are only two possibilities: they’re ignorant and believe what they’re saying, or they’re dishonest, know very well that they are lying. Watching this kind of thing for many years, I started to realize that a better way of thinking about what was going on is that for many people (mathematicians being somewhat of an exception) the issue of truth just isn’t very relevant. Newt Gingrich and Michio Kaku likely weren’t thinking at all about whether what they were saying was true, they were thinking about what would get votes, sell books, or otherwise further their goals in life. Gingrich was doing what he was doing to save the republic, Kaku to pursue the dreams of Einstein, but both had enthusiastically entered a post-truth environment.
Over the last decade or two, things have gotten much, much worse. Those with a lot of influence in fundamental theoretical physics have driven the field to intellectual collapse by continuing to heavily promote failed ideas. The scientific method is based on abandoning failed ideas and moving on to better ones. As an undergraduate at Harvard I watched Glashow, Coleman, Weinberg, Witten and others quickly abandoning that which didn’t work and moving on to impressive new ideas, with more of the same at Princeton during my graduate years. These days Harvard Physics features a group of people devoted mainly to propping up the failed string theory program (Vafa with the “swampland”, Strominger with “A+++” and Jafferis with the wormhole publicity stunt). The situation at the IAS/Princeton isn’t a lot better.
On the American democracy front, the Trump phenomenon embodies post-truth in its purest form, with the full triumph now of a movement devoted to saying whatever will get them to power, with less than no interest in whether any of it is true. I’ve spent a lot of time trying to understand why voters in the US voted the way they did in this latest and recent elections. Taking a look at last night’s exit polling, the answer is pretty simple. Rich and poor voted much the same way, but those with the least education voted for Trump by a 28% margin, those with the most education voted for Harris by a 21% margin. The polite term for the first group seems to be “low information voters”, but what’s going on is that education is exactly what gives you the tools to look for the truth and not get taken in by lies.
The situation has gotten dramatically worse in recent years, as people get their information from social media, with the rise of powerful algorithms designed to generate outrage and “engagement” (sometimes designed and funded by bad actors). These send even some of the smartest people around deep into rabbit holes of lies.
So, given all this, how does one live a fulfilling life in a post-truth world? I’m 67 years old, now see little chance I’ll be around to see a return to the sort of world I once knew where what was true mattered. On the citizen in a democracy front, over the last few days I’ve adopted a new policy. When I’m reading anything, at the word “Trump” I stop and move on to something else. Other terms will get added to that algorithm as needed. What’s going on is all too clear, there’s nothing I can do about it, and I need to stop wasting time and energy thinking about it more. I’ve deleted the Twitter account I was using (@peterwoit, not the @notevenwrong blog post announcement account) and won’t anymore waste time in that sewer. I’ll miss stringking42069, but one has to make sacrifices.
On the theoretical physics front, I’ll give up wasting time paying attention to what string theorists are up to, and try to concentrate on more worthwhile intellectual activities. The blog will continue though, since it’s one of the main positive things I can do to make a small dent in the post-truth information environment. I’ve always benefited greatly from the many readers who write to me to tell me about things I may not have seen. Keep those cards and letters coming, especially since I’ll be spending less time looking for something new on the physics side of many of the usual topics I’ve covered.
Due to massive increases in the volume and sophistication of trolling, blog comments are now all moderated. If you want to argue that it’s all the Democrats fault (yes, I know that they have their own post-truth problem with identity politics), or that theoretical physics is doing just fine, please go away. If you have an insightful and constructive suggestion about how to live in the post-truth world, I’m willing to listen.
