Models in the Mind
Multiple Conscious Sites
One can look at the human brain as using more than one kind of model or as having more
than one conscious site. It could be either, but let us assume that it operates with more than
one kind of model. Some sites are based on social models where others may be based on
mathematical models. Take a set of humans and ask them the following question:
The average answers will group around the reality of 30% probability that the man is an
engineer.* The reason is that you have reached the mathematical consciousness or
mathematical modelling part of the human mind. The question may be made with 70
engineers and 30 lawyers and with the question being how many lawyers instead of
engineers. The results will be approximately the same because the question is simple enough
to encourage the average Western mind to utilize the consciousness or modeling that was
used in their mathematics classes.
But then add any other social description to the test and human will typically use her social
consciousness to generate the answer. The mathematical impact will be overlooked
completely. Take the following description given in the reference book:
Notice that the human subject is reminded of the mathematical probability during the asking
of the question. No matter, the humans will typically ignore the math in favor of clues given to
their social consciousness by the description of the man and his hobbies.
The human mind is, for the most part, a survival mechanism which developed to provide
survival of the individual as part of a society. The ability with math is typically minor by
Humans who lack social skills may treat people inappropriately but be mathematical
geniuses. From a normative point of view, these math and physics geniuses are defective.
There are humans who insist in stating that the earth goes around the sun when the society
around her tells her that the sun goes around the earth and if she doesn't agree, she will suffer
confinement. When such an event happens, most humans will utilize their intelligence for its
intended purpose, namely, the survival of the individual.
Students who don't settle down in the modern classroom are no longer confined as was done
in the past. Today, such geniuses are made 'normal' by administering Ritalin.

Picture a group of 100 men consisting of 30 engineers and 70 lawyers. We choose one man at random
from the group. What is the probability that the man chosen is an engineer?
Jack is a 45-year-old man. He is married and has four children. He is generally conservative, careful, and
ambitious. He shows no interest in political and social issues and spends most of his free time on his many
hobbies which include home carpentry, sailing, and mathematical puzzles.
The probability that Jack is one of the 30 engineers in the sample of 100 is _____%.
