to rebuild his operations? The thinkers who focused on con-
sequences lived in simpler eras. Perhaps Mozi would have
been less confident about foreseeing beneficial consequences
if he could have stepped into a time machine and glimpsed
the complex, fluid, confusing, and incomprehensively inter-
dependent world we live in today.
The second serious practical challenge is in our heads. We
just aren’t very good at thinking rationally and objectively—
not just about the unknowable future, but about the past
and even the present. Gray areas sometimes bring out strong
emotions and make it hard to think soundly, but that is just
the tip of the iceberg. The challenge runs much deeper.

The problem is that our minds can be viewed as having
two basic systems for making decisions. One is a recent evolu-
tionary development. It is conscious, analytical, and rational.
It looks objectively at facts and ways of framing or analyzing
those facts. The other system has been part of human nature
for much longer. It is unconscious and instinctive. It was prob-
ably crucial to the survival of our distant ancestors. When we
make decisions, which system do we use? Countless careful
studies indicate that our subterranean, instinctive decision
system dominates the rational parts of our minds.
A truly remarkable example is a recent study involving
Israeli parole judges. Researchers found that the first pris-
oner they reviewed in the morning had a 65 percent chance
of parole. This was also true for the first prisoner reviewed
after lunch. In contrast, the prisoners considered just before
lunch and at the end of the day had little chance of parole.
These judges were experts, they were trained in the law, they
were men and women of integrity, they were following clear
