In Superforecasting: The Art & Science of Prediction,
social scientist Philip E. Tetlock and journalist Dan Gardner (Crown
Publishers, September 2015) observe that at its heart, politics is
usually about predicting the future. The exercise boils down to finding
and implementing policies that will do best for the public interest
(general welfare or common good), regardless of how one defines the
concept.
What most accurately describes the essence of
intelligent, objective, public service-oriented politics? Is it
primarily an honest competition among the dominant ideologies of our
times, defense of one’s social identity, a self-interested quest for
money, influence and/or power or some combination? Does it boil down to
understanding the biological functioning of the human mind and how it
sees and thinks about the world? Is it some something else entirely?
Subject to caveats, Superforecasting comes down on the side of getting brain biology or cognition right. Everything else is subordinate. Superforecasting
describes Tetlock's research into asking what factors, if any, can be
identified that contribute to a person’s ability to predict the future.
Tetlock asks how well intellectually engaged but otherwise
non-professional people can do. The performance of volunteers is
compared against experts, including professional national security
analysts with access to classified information.
The conscious-unconscious balance:
What Tetlock and his team found was that interplay between dominant,
unconscious, fact- and common sense-distorting intuitive human cognitive
thinking (“System 1” or the “elephant”
as described before) and our far less-powerful but conscious, rational
thinking (“System 2” or the “rider”) was a key factor in how well people
predicted future events. The imbalance of power or bandwidth between
conscious thinking and unconsciousness thinking is estimated to be at
least 100,000-fold in favor of unconsciousness.
The trick to optimal performance appears to be found in people who are
able to strike a balance between the two modes of thinking, with the
conscious mind constantly self-analyzing to reduce fact distortions and
logic biases or flaws that the unconscious mind constantly generates.
Tetlock observes that a “defining feature of intuitive judgment is its
insensitivity to the quality of the evidence on which the judgment is
based. It has to be that way. System 1 can only do its job of delivering
strong conclusions at lightning speed if it never pauses to wonder
whether the evidence at hand is flawed or inadequate, or if there is
better evidence elsewhere. . . . . we are creative confabulators
hardwired to invent stories that impose coherence on the world.”
Coherence
can arise even when there's insufficient information. In essence, the
human mind evolved an ‘allergy’ to ambiguity, contradictions and
concepts that are threatening to personal morals, identity and/or
self-interest. To deal with that, we rapidly and unconsciously makes
those uncomfortable things go away.
It turns out, that with some training and the right mind set, a few
people, “superforecasters”, routinely trounce professional experts at
predicting future events. Based on a 4-year study, Tetlock’s “Good
Judgment Project”, funded by the DoD’s Intelligence Advanced Research
Projects Agency, about 2,800 volunteers made over a million predictions
on topics that ranged from potential conflicts between countries to
currency and commodity, e.g., oil, price fluctuations. The predictions
had to be precise enough to be analyzed and scored.
About 1% of
the 2,800 volunteers turned out to be superforecasters who beat national
security analysts by about 30% at the end of the first year. One even
beat commodities futures markets by 40%. The superforecaster volunteers
did whatever they could to get information, but they nonetheless beat
professional analysts who were backed by computers and programmers,
spies, spy satellites, drones, informants, databases, newspapers, books
and whatever else that professionals with security clearances have
access to. As Tetlock put it, “. . . . these superforecasters are
amateurs forecasting global events in their spare time with whatever
information they can dig up. Yet they somehow managed to set the
performance bar high enough that even the professionals have struggled
to get over it, let alone clear it with enough room to justify their
offices, salaries and pensions.”
What makes superforecasters so good?:
The top 1-2% of volunteers were analyzed for personal traits. In
general, superforecasters tended to be people who were open-minded about
collecting information, their world view and opposing opinions. They
were also able to step outside of themselves and look at problems from
an “outside view.” To do that they searched out and integrated other
opinions into their own thinking.
Those traits go counter to the
standard human tendency to seek out information that confirms what we
already know or want to believe. That bias is called confirmation bias.
The open minded trait also tended to reduce unconscious System 1
distortion of problems and potential outcomes by other unconscious
cognitive biases such as the powerful but subtle “what you see is all
there is” bias, hindsight bias and scope insensitivity, i.e., not
giving proper weight to the scope of a problem.
Superforecasters
tended to break complex questions down into component parts so that
relevant factors could be considered separately. That tends to reduce
unconscious bias-induced fact and logic distortions. In general,
superforecaster susceptibility to unconscious biases was lower than for
other volunteers in the GJP. That appeared to be due mostly to their
capacity to use conscious (System 2) thinking to recognize and then
reduce unconscious (System 1) biases. Analysis revealed that
superforecasters tended to share 15 traits including (i) cautiousness
based on an innate knowledge that little or nothing was certain, (ii)
being reflective, i.e., introspective and self-critical, (iii) being
comfortable with numbers and probabilities, (iv) being pragmatic and not
wedded to any particular agenda or ideology, and, most importantly, (v)
intelligence, and (vi) being comfortable with (a) updating personal
beliefs or opinions and (b) belief in self-improvement (having a growth
mindset). Tetlock refers to that mind set as being in “perpeutal beta”
mode.
Unlike political ideologues, superforecasters tended to be pragmatic,
i.e., they generally did not try to “squeeze complex problems into the
preferred cause-effect templates [or treat] what did not fit as
irrelevant distractions.” Compare that with politicians who promise to
govern as proud progressives or patriotic conservatives and the voters
who demand those mind sets.
What the best forecasters knew about a
topic and their political ideology was less important than how they
thought about problems, gathered information and then updated thinking
and changed their minds based on new information. The best engaged in an
endless process of information and perspective gathering, weighing
information relevance and questioning and updating their own judgments
when it made sense, i.e., they were in “perpetual beta” mode. Doing that
required effort and discipline. Political ideological rigor such as
conservatism or liberalism was generally detrimental.
Regarding
common superforecaster traits, Tetlock observed that “a brilliant puzzle
solver may have the raw material for forecasting, but if he also
doesn’t have an appetite for questioning basic, emotionally-charged
beliefs he will often be at a disadvantage relative to a less
intelligent person who has a greater capacity for self-critical
thinking.” Superforecasters have a real capacity for self-critical
thinking. Political, economic and religious ideology is mostly beside
the point. Instead, they are actively open-minded, e.g., “beliefs are
hypotheses to be tested, not treasures to be protected.”
Tetlock
asserts that politicians and partisan pundits opining on all sorts of
things routinely fall prey to (i) not checking their assumptions against
reality, (ii) making predictions that can’t be measured for success or
failure, and/or (iii) knowingly lying to advance their agendas.
Politicians, partisan pundits and experts are usually wrong because of
their blinding ideological rigidity and/or self- or group-interest and
the intellectual dishonesty that accompanies those mind sets. Given the
nature of political rhetoric that dominates the two-party system and the
biology of human cognition, it is reasonable to argue that most of what
is said or written about politics is more spin (meaningless rhetoric or lies-deceit) than not.
Is Tetlock’s finding of superforecasters real? Does that
point to a human potential to at least partially
rationalize politics for individuals, groups, societies or nations?
Pragmatic politics focused on the public interest for those uncomfortable with America's two-party system and its way of doing politics. Considering the interface of politics with psychology, cognitive science, social behavior, morality and history.

DP Etiquette
First rule: Don't be a jackass.
Other rules: Do not attack or insult people you disagree with. Engage with facts, logic and beliefs. Out of respect for others, please provide some sources for the facts and truths you rely on if you are asked for that. If emotion is getting out of hand, get it back in hand. To limit dehumanizing people, don't call people or whole groups of people disrespectful names, e.g., stupid, dumb or liar. Insulting people is counterproductive to rational discussion. Insult makes people angry and defensive. All points of view are welcome, right, center, left and elsewhere. Just disagree, but don't be belligerent or reject inconvenient facts, truths or defensible reasoning.
