Or to be more precise, debate about the financial institutional framework edition.
How should banks be regulated? Ten years ago, this question would have only interested a few specialists. Discussions about bank supervision and the role of the central bank were way too boring for the general public1. Besides, bankers surely knew what they were doing?
The global financial crisis and its aftermath changed this complacent attitude. The existing rules did not prevent the worse financial crisis since the 1930s. Governments had to bail out banks at a moment’s notice. Politicians took drastic decisions during the panic of September 2008. While those actions were taken with little democratic oversight, national leaders2 were the only agents willing and able to stop the collapse.
The internet offers an endless stream of analyses and opinions. On this blog, I sometimes comment on articles written by people who have a large audience. My disagreement with better known commentators is regularly confused for arrogance. “What do you know, dude? You are a blogger, the other guy is a professor.” Such statements show how easily people refer to authority1 instead of critically evaluating the arguments.
When I point out dubious logic, that does not mean the authors have nothing interesting to say. Quite the contrary, I often agree with them on many points. But pinpointing disagreements and calling assumptions into question can be very insightful. So when I critique for example Paul Krugman or Geert Noels, I’m not saying “neglect these fools”. I hope that readers will take into account my point of view, and confront it with that of others. I am no contrarian for the sake of being a contrarian.
This ideal dynamic is illustrated by historians David Wootton and Joel Mokyr. Mokyr’s book A Culture of Growth: The Origins of the Modern Economy explains why Western Europe was the first region in the world to make sustained technological and economic progress. In his review, Wootton summarizes the thesis put forth in the book. Then, he argues that the story is incomplete. In the comments below the review, both gentlemen defend their points of view.
That is one of the advantages of the internet. Well-informed contributors can quickly challenge opinions. I have learned a lot over the years from (often anonymous) online commentators. It is a shame many media have closed down the comment sections. Blocking feedback does not add to their credibility.
I would advise scientific journals to enable comments as well. Papers go through peer-review before they are published, but the reader cannot see these discussions. Commenting on a scientific article via a new publication takes a lot of time. Getting out new results and contradictory information faster would accelerate learning in all disciplines. Blogs can also expose disinformation.
If you don’t agree with me, you can always let me know in the comments!
Update 17/05/2017: Chris Said has a nice blog post on different levels of understanding. He calls the dialectic process of reaching the next level ‘Learning by flip-flopping‘. Open discussions as I advocate above are the means to transcend your previous, more basic knowledge.
There is a Dutch proverb that says “een ezel stoot zich geen twee keer aan dezelfde steen”. Its literal translation is “a donkey doesn’t bump against the same stone twice”, but is usually translated as “once bitten, twice shy” or “a fox is not caught twice in the same snare”.
The proverb means that people don’t (or shouldn’t) make the same mistake twice. Even a dumb animal like the donkey is smarter than that.
Apparently, the political pundits are dumber than donkeys when it comes to Trump. For over a year, they have underestimated his chances. Here is a list of Trump predictions, in which the ‘You are now here’ marker has continuously moved down:
This was not surprising. Krugman is the prototype of a sheltered elite living in a bubble. How many Trump voters do you think he personally knows? Probably none. Rather, he inhabits an echo chamber full of likeminded people. Just to give some examples, I’m talking about people like Noah Smith, Brad DeLong, Paul De Grauwe and Simon Wren-Lewis.
All have academic backgrounds, cushy jobs, and liberal technocratic preferences. They all read papers like the New York Times. They all are given a forum in the quality press. The all “know” Trump is an incompetent idiot. They all “know” that “facts have a well-known liberal bias”.
