While reading Tim Harford’s book, ‘Adapt’, I was thinking
about the implications for democracy of the theme running through the book. I have been thinking a lot about democracy recently.
The theme is what Harford refers to as Palchinsky’s principles:
- Variation: seek out new ideas and experiment.
- Survivability: ensure that the scale of experiments is not so big that failure leads to catastrophe.
- Selection: seek feedback and learn from failures.
The theme is also captured fairly well by the books sub-title:
‘Why success always starts with failure’.
Peter Palchinsky was a talented engineer in the Soviet Union.
He was arrested by the secret police in 1928 and never seen again. His main
‘crime’ seems to have been that he refused to recant after he had been
denounced for objecting to looming technological disasters.
Harford applies Palchinsky’s principles to a wide range of
things, including the management of the war in Iraq by the US miltary, the events
leading to the design of the Spitfire in England prior to World War 2,
provision of foreign aid, climate change mitigation, financial meltdowns,
corporate strategy and self-management.
One of the points that came through strongly to me is that even
hierarchical military organizations need to learn strategy from their
experiences in the field. I knew that was true of big business organizations,
but I had not previously thought of armies as having to experiment in order to
find the best approach to adopt in different conflicts. It seems that senior people
in the US military were not aware of that either during much of their occupation
of Iraq.
Harford’s discussion of the global financial crisis seems
sensible. He suggests that the failure of experiments with sub-prime mortgages
would not have led to a major financial crisis in the absence of tight coupling
in financial markets via credit default swaps. These appeared to provide the
banks with a greater margin of safety, but actually linked their fortunes
closely to insurance companies. As a consequence, the sub-prime mortgage
problem was transmitted from insurance companies to banks (and then to governments).
The solution is obvious with hindsight - decouple the system so that banks are
less likely to fail and the failure of individual banks does not lead to system
failure. I would add that governments should adopt a ‘no bailouts’ policy and
back that up with a requirement for banks to guarantee immediate and automatic transfer
of ownership of all assets to depositors and bond holders if they (the banks) are
unable to meet their interest or repayment obligations.
The points about self-management were not new to me. But it
didn’t hurt to be reminded of the importance of trying new things in a context
where failure is survivable - and of being prepared to learn from failure. It
helps to remember that the failure of our experiments does not necessarily
reflect on our competence unless we fail to learn from them.
The closest Tim Harford comes to discussing democracy in this
book is his discussion of charter cities. In his version, governments establish
the rules of a new city as an experiment to see if citizens and business want
to live there. If the experiment
succeeds it can be repeated elsewhere. If it fails, that failure is survivable.
In reading Tim Harford’s book I was reminded of a claim by
Timothy Ferris:
‘A liberal democracy in action is an endlessly changing
mosaic of experiments, most of which partially or entirely fail’ .
The claim is made in his book, ‘The Science of Liberty’
(2010). In my discussion I suggested that Ferris’ view of liberal democracy, as
akin to scientific experimentation, was a desirable ideal rather than a
description of how democratic systems actually work. I suggested that elections
seemed to be a reasonably effective way for citizens to avoid being governed by
despots, to get rid of politicians who are obviously corrupt and to experiment
with new policies. However, democracy departs from the scientific ideal because
the democratic process is not good at ending policy experiments that partially
fail. The most radical reforms rarely involve more than a tweaking of failing
policy experiments.
If we look at democracy in terms of Palchinsky’s
principles there are problems all over the place. There are at least two
problems relating to willingness to experiment. First, there is often a strong
bias in favour of the status quo because of loss aversion. If there is
potential for any politically influential group to be disadvantaged by a policy
experiment then it is unlikely to be conducted.
Second, there is often a reluctance to conduct experiments unless they
involve the whole of a jurisdiction - questions of fairness are often perceived
to be involved.
There are problems relating to survivability. Social
experiments are often entered into by governments without adequate consideration
of longer term implications for system survival. For example, welfare
assistance that is granted when it seems to be affordable is often difficult to
withdraw when economic circumstances change for the worse. Some European
democracies are currently faced with survivability problems as a result of
excessively ambitious social experimentation in the past.
There are also problems in seeking feedback and learning
from failures. As noted above, the democratic process is not good at ending
policy experiments that partially fail. This reflects two problems. First, governments
are often reluctant to accept policy failure because it may have electoral
consequences. Second, those who benefit from failing policy experiments are
reluctant to see them end and often have the political clout to prevent this
from happening.
So, can democracies learn to adapt? We have natural
experiments that help us to answer that question. The older democracies have so
far shown a capacity to adapt. They have been able to learn from some of their
mistakes by adopting institutional innovations to improve the effectiveness of
government and, to a lesser extent, to contain the growth of government
responsibilities.
There is also potential for the democracies to learn from
the success and mistakes of other democracies. For example, there is probably a
lot to be learned from the modern experience of democracy in Greece, as well as
from ancient history. A recent article by Steve Horwitz makes the point very well.
The idea of learning from the mistakes of others has more
general relevance. It might even be worth adding to Palchinsky’s principles. However,
it is probably harder to learn from mistakes made by others than to learn from
your own mistakes. When my father told me that I should learn from his
mistakes, as he often did, my response was that it would be much more fun to
make my own mistakes. Looking back now, though, I don’t think my father actually
made many mistakes that I could learn from.
