Critical
Thinking Programs:
Why They Won't Work
by Mortimer Adler, Ph.D.
American education in the twentieth century has
been full of "buzzwords." They represent voguish
panaceas that, originating locally, develop into
nationwide manias. Sweeping the country for a short
time, they die away leaving no memorable results.
The most recent and most ill-conceived is the mania
to develop programs of instruction in critical
thinking, using manuals and other "how-to" devices,
as if thinking could be taught in and of itself as
an abstract skill.
There can be no question that developing in the
minds of our students the ability to think --
critically at least, if not also creatively --
should be a prime objective of basic schooling.
Unless students can be trained to think critically,
none of the other objectives of basic K-12
schooling can be achieved. They cannot develop
skill in the language arts, in the operations of
mathematics, and in the procedures of scientific
investigation. Their understanding of important
ideas and issues cannot be increased and
deepened.
What is misconceived is not the objective
itself, but rather the means for achieving it. It
is characteristic of current educational thinking
that, once an objective of schooling comes to the
fore and receives national recognition, the means
proposed for achieving it consist of setting up
specially devised programs for the purpose.
In some cases, that may be the right thing to
do. But with regard to thinking, it is completely
wrong. I would almost say that, for critical
thinking, devising a special program to produce the
desired result is a chimerical effort. It cannot be
done.
There is no such thing as thinking in and of
itself. All the thinking any of us do is thinking
about one subject matter or another, or it is the
thinking we do in the process of performing other
acts of the mind.
We cannot learn to read and write very well, or
speak and listen well, without learning how to do
all these things thoughtfully. To be a thoughtless
reader (i.e., to read without thinking as one
reads) may result in pleasure or help one go to
sleep, but it cannot result in the growth of
knowledge understood or in an increase of
understanding itself. The same holds true for the
performance of mathematical operations and
engagement in scientific investigation. These
things cannot be done without thinking, or, if done
thoughtlessly, the educational result will be
nil.
Good schooling should involve a great deal of
discussion, interchanges of questions and answers
between teacher and student and between students
with one another. Such discussion, if it is to be
educationally profitable for all concerned, must
involve them in thinking. It certainly should not
be as thoughtless as cocktail-party chitchat, or
like the unthinking exchange of opinions or
prejudices in ordinary bull sessions.
Those engaged in educationally profitable
discussion will be engaged in agreeing or
disagreeing, arguing when they disagree, and giving
reasons for disagreements. They will be making and
defending generalizations, or challenging
generalizations made by others. They will be
judging by weighing evidence pro and con, or by
examining the validity of reasons for making one
claim or another concerning what is true or false,
more or less probable. They will be asking and
answering questions about the consistency or
inconsistency of things asserted or denied, about
their presuppositions and their implications, and
about the inferences involved therein.
All this is obviously critical thinking on the
part of those engaged in discussing, as well as
those engaged in reading, writing, speaking,
listening, calculating, providing, testing,
observing, measuring, and trying to draw
conclusions from what has been found by observation
and measurement. All of the words just used are
participles of verbs that signify acts of the mind
in thinking. These acts can be performed either
poorly or well. They are performed well only by
those who have acquired skill in performing them,
skill that in each case is possessed as a good
habit of performance.
How are such intellectual habits of skill
developed? Exactly in the same way that all bodily
habits of skill are developed: by coaching, not by
didactic instruction using textbooks that state the
rules to be followed.
Many years ago, I taught courses in logic, using
texts that stated the laws of thought, the rules to
be followed in making inferences and judging them,
and in avoiding fallacies. I discovered that
students able to get high marks in a logic course
were not, as a result, able to think critically or
to read and discuss thoughtfully the difficult
books assigned in seminars I conducted. Logic is no
longer required in most colleges, for this very
reason.
The programs in critical thinking now being
advocated from coast to coast are minuscule and
oversimplified versions of the much more rigorous
course in logic that I taught in college. And they
will be just as ineffective in producing students
who can think critically in other courses. Nor will
they train teachers how to think critically. That
training should have been accomplished by the
education they received before they started to
teach.
How do our law and medical schools train future
practitioners to think the way lawyers and
physicians should be able to think? By giving them
instruction in critical thinking? No, by demanding
that they learn how to think about legal and
medical matters in all courses taught in these
professional schools and, after that, in hospital
internships and in law offices. The method of
instruction throughout is that of coaching, with
student performances corrected when they are poorly
done and with insistence that the right way of
performing be done over and over again until the
requisite skill becomes a firm and stable habit of
operation.
The misconception that underlies the now widely
prevalent educational vogue is that thinking is a
skill that can be acquired in isolation from all
the other skills that enable us to use our minds
effectively, in the performance of which we are
involved in judging, reasoning, problem-solving,
arguing, and defending or rejecting
conclusions.
Since that is not the case, we should not be
developing programs in critical thinking to achieve
the educational objective about which we all agree.
Instead, we should try to be sure that students are
coached in thinking in every course that is taught
-- taught, one hopes, by teachers who know how to
think. Such coaching will, of course, pay attention
to the laws or rules of thought that are taught in
courses on formal logic, but it will not be
regarded as effective coaching simply because
students can recite the logical lessons they have
learned.
In short, if all teaching required students to
think about what is being taught, that by itself
would suffice. Teaching that fails to do this is
nothing but indoctrination. Learning that does not
involve thinking is nothing but the memorization of
facts not understood, resulting in the formation of
mere opinions, not the possession of genuine
knowledge and understanding. To turn out thoughtful
citizens and learners -- persons able to think well
and critically in everything they do, no program of
instruction in critical thinking is required.
