Civilization as Experiment
Mining the insights of humanity.
From birth, parents raise us in different ways, teachers
teach us in different styles, and doctors treat us with different medicines and
give us different advice. These
experiences set us upon our paths in life, sculpting how we learn and how we stay
healthy. We can think of each
interaction between a teacher and a student, or between a doctor and a patient, as a little
miniexperiment, with an outcome that can be evaluated: Did the student learn and become able to use
the information to do creative and useful things throughout life? Did the patient improve in health and
develop proactive health-related behaviors?
With almost one million physicians, and about four million educators of
children, in the U.S. alone, we are as a society conducting millions of
perturbations of behavior every day.
However, we do not take advantage of the enormous amount of empirical
data that, in principle, could be collected and analyzed in the process. A tool for generating and mining such a
data set could not only reveal general empirical facts and principles about how
best to teach, or to prevent and treat disease, but also allow individuals to monitor their
own personal parameters that govern how they best operate, empowering them to
better themselves.
Consider the idea of an ongoing clinical
trial. Currently a clinical trial for a
drug involves, typically, a blinded test of a treatment versus a control, which lasts
a certain amount of time, and progresses in multiple stages, increasing the
number of people each time, and looking for certain outcomes. Then, if the trial ends successfully, the drug
can be sold. However, it's been observed
that a great many drugs likely work for only a fraction of the patients who
receive them. Indeed, drugs that may be bad if prescribed indiscriminately are sometimes useful for specific subpopulations (e.g., consider the story of thalidomide). Furthermore, after a drug is out in the world, it can be used
off-label by doctors. If side effects appear in a subpopulation of
patients, there isn't a forum to interactively analyze the properties of that
subpopulation in a rapid way. Clinicians can publish the results of such
observations in journals, but such observations often stand alone.
A complementary approach might be to continually
accumulate data about a drug as it is used to treat different diseases, in
different populations, over time. Each
individual patient would be permanently associated with a data point, so that
follow-up and further examination would become possible. As genomic information, brain imaging, and
other information-dense measures become increasingly cheap to acquire, tracking
multiple variables within a patient over long periods of time will become more
and more valuable, allowing one to find better predictors of future outcomes in response to a specific treatment,
and to derive conclusions that would be impossible from a limited snapshot of a
person's life. This could speed up the
process of testing out technologies, allowing evidence to be accumulated and
analyzed in a distributed and open fashion, and enabling cures to be developed and tested
faster. It could also simplify prospective studies, in
which patients are tracked before and after disease onset, say for conditions
such as autism or schizophrenia; right now it is very hard to do this because
detailed studies of people before a disease occurs are difficult for all but
the most common diseases. With
integrated database design and accessibility, it would become possible to
perform this analysis. Such a system
would also need to have instantaneous peer review that would occur in a
rewardable way; the system must track real identities and real reputations of people who comment on or synthesize insights from the database, to synthesize accountability, reputation,
and trust, and to separate the experts from the nonexperts. Perhaps free access to the
database's wealth of data would motivate people to contribute; people who contribute less, or who contribute lower-quality judgment, might instead pay to access it.
It's possible that this methodology could apply to other
domains of life, exploring how to assist people to become better--for
example, consider how to evaluate trajectories for the approximately two million inmates in U.S. prisons. Or consider mental health, in which many styles of
therapy are continually being explored by a diverse set of psychologists, therapists,
and psychiatrists. Or the economy: perhaps a way to help economies self-regulate is to build in self-analysis at
every step of the way, continuously generating models and testing theories to catch disasters before they happen.
How many approaches
to life ever get validated? When does a
strategy or method need to be personalized to an individual, and when is an
insight a general piece of wisdom? Systems that enable
these questions to be answered by providing a continuously updated snapshot of
the best practices of the world may change the way we live, and enable a new age
of rational decision making. "Those who
can't remember the past are doomed to repeat it." Well, currently that's just about all of us.

Averting Disasters, Preventing Problems
Strategies to overcome the shortsightedness of the human mind.
We are terrible at solving future problems before they become big. A friend
of mine who worked for decades as a governmental security advisor was once told
by an official, "Unless there are bodies on the ground, we can't pay
attention to it." This property of the human mind affects us at the
personal, community, and global levels, whether it's dealing with diet and
exercise and debt, or the future of Social Security, or global climate change--all
scenarios where people must invest effort now, to solve a problem that won't
hit until some time passes. Now, it's one thing to complain about how bad we
are at this problem (as psychologists have been gleefully pointing out for many
years). But can we do anything about it? Can we engineer new tools to enhance
our judgment, and to augment our ability to objectively deal with problems?
Easy gimmicks and fixes don't work: this problem might be fundamental to the
human condition. Information is not enough to enable good decision making. We
need to improve how we act on information, and that means utilizing emotion as
a tool. Now, emotions of the moment shape how we prioritize and act, whereas
distant emotions have little or no impact on our current actions. Thus it is
hard to resist that extra cheese Danish or that new car--because we feel
current urges and emotions right now, while the distant emotion that would accompany
a medical problem or a financial problem isn't real to us. Conversely, an
immediate problem is far more painful than a future one: it is easy to
procrastinate about something laborious, or to rush to solve an emergency. So
immediate problems will override future ones, grabbing our attention because of
the immediate anxiety and stress produced.
Thus, one possible principle of prevention is: develop tools to help
yourself feel future emotions now. Create visceral visualizations of the different
outcomes, so that you can feel the feelings that result from each one. Emotions
are shortcuts, and while they can be destructive when gone awry, they can be
harnessed to augment rational behavior, if you understand your mind. It is
possible to make software tools that enable visceral visualizations of the
consequences of current actions. When I schedule future
activities on my to-do list, for example, I often embed appropriate
emotional cues in the list, so that when the time comes to act, it's easier for
me to do what I've planned. Perhaps software that enables additional visual,
auditory, and other-modality cues to enhance this process--and personalizes the
emotion to the individual--could help boost the power of the human mind, to
actively prevent problems. I wonder if such a tool, properly developed, could
be a true cognitive prosthetic to enable better decisions and fewer disasters
in the future.

Research as a Community-Building Activity
The potential impact of participatory science, personal and global.
Community activities, especially those that bring together people of all
ages, seem to be increasingly rare and brief lived in this busy world. Yet they
provide a lot of meaning in people's lives, for reasons ranging from the deeply
personal to the broadly impactful. I used to volunteer for the San Francisco
Symphony, selling discounted concert tickets to college students. This activity
brought together people of all ages to contribute to the survival of the arts,
and to learn from one another about topics ranging from fundraising to musical
composition to the role of music in health. And it yielded many enduring
friendships, formed in the act of pursuing a common goal. From this experience
and others, I learned that community participation in an activity gives people
a stake in it, ensuring its endurance and prominence. It also increases the
diversity of people who contribute to the activity, beyond just the
specialists, thus broadening the scope of the activity and increasing its power
and relevance. Finally, such activities enrich the meaning of the lives of the
people participating, enabling them to contribute to the well-being of the
world and building communities of interaction and support, which is perhaps why
the absence of such activities in one's life can be palpable at times.
Scientific research, when compared with other areas in which people can
volunteer their time, seems to be relatively unexplored as a community-building
activity. The conventional wisdom implies that scientific research is something
you do when you are training or in school, so that afterward you can go off to
make useful products and provide valuable services. To caricature only
slightly: the public is often painted as a confused, and sometimes suspicious,
consumer of scientific information, and the production of science is often
painted as an abstruse art, and occasionally a dangerous one. And the two sides--the
public and the producers of science--meet only occasionally, through
journalists and explicit outreach efforts. It is, however, widely accepted in
this interdisciplinary age that scientific discovery, to be the engine of
change that is needed, broadly benefits from the interaction of people from
diverse backgrounds. Thus, I believe that we should think about ways to involve
all community members broadly in the act of research itself, working in groups
to discover and share knowledge.
Involvement of the public in the act of science would shape the kind of
science being done, perhaps increasing the impact of science on daily life.
Community involvement in the act of research would also make science more
understandable, and perhaps more familiar, to the public, because people would
be engaged in its framing and communication. What better way to increase
scientific literacy, make the benefits of science clear, and quell myths and
spread facts than to give all people a stake in the act of discovering science?
Maybe the way the world sees some currently controversial topics--stem cells,
climate change, energy sources--would be different if more people engaged in
the act of testing hypotheses and examining data. Community participation in
science would also be enormously personally enriching, providing exercise in
thinking and problem solving (something that is useful in all problem domains,
throughout life) and empowering people to contribute directly to the betterment
of society in a broadly impactful way.
More and more fields are being democratized by strategies that make it easy
for people to create: bloggers can write news stories, teenagers can film
movies and upload them, and anyone can compose a novel and get it in front of
millions of readers. People talk about "participatory media," but
what about "participatory science"? The opening of science is
occurring slowly--led by the open-access journals, perhaps, and by some groups
sharing their data and insights in increasingly informal ways. But the opening
up of the act of scientific research itself is still not widespread. I propose
that we begin to create programs in which members of the public, of all ages,
can meaningfully volunteer in laboratories, working together on problems--perhaps
only for a few hours a week, but over an extended period of time, to achieve
depth. If you are a lab head, think about inviting someone new into the fold.
If you are interested in participating in scientific research, reach out to
people nearby and see if you can help.
Most scientific funding agencies currently focus on the training and
development of young people. "K-12, undergraduate science majors,
non-science majors, and graduate students," the NSF helpfully suggests as
key demographics to focus on in order to broaden the impact of one's research.
But it seems to me that programs that engage other demographics--for example,
retired individuals who want to create and mentor, with their wealth of
knowledge, practical experience, and wisdom--would not only provide new
perspectives for young people entering science, but also enrich the lives of a
segment of the population that is not actively recruited to the intellectual
process by many current institutions. Working with other scientists is just
fun. It is highly interactive and engaging, and can cover vast intellectual and
emotional ranges, as well as bring people together, as with any meaningful
community activity. And there will always be important problems to solve.
