| | #2621 | | The inability to benefit from feedback appears to be the primary cause of
pseudoscience. Pseudoscientists retain their beliefs and ignore or distort
contradictory evidence rather than modify or reject a flawed theory. Because
of their strong biases, they seem to lack the self-correcting mechanisms
scientists must employ in their work.
-- Thomas L. Creed, "The Skeptical Inquirer," Summer 1987
| | | #2622 | | Finding the occasional straw of truth awash in a great ocean of confusion and
bamboozle requires intelligence, vigilance, dedication and courage. But if we
don't practice these tough habits of thought, we cannot hope to solve the truly
serious problems that face us -- and we risk becoming a nation of suckers, up
for grabs by the next charlatan who comes along.
-- Carl Sagan, "The Fine Art of Baloney Detection," Parade, February 1, 1987

Don't have aesthetic convulsions when using them, either.
| | | #2625 | | As the system comes up, the component builders will from time to time appear,
bearing hot new versions of their pieces -- faster, smaller, more complete,
or putatively less buggy. The replacement of a working component by a new
version requires the same systematic testing procedure that adding a new
component does, although it should require less time, for more complete and
efficient test cases will usually be available.

| | | #2626 | | Each team building another component has been using the most recent tested
version of the integrated system as a test bed for debugging its piece. Their
work will be set back by having that test bed change under them. Of course it
must. But the changes need to be quantized. Then each user has periods of
productive stability, interrupted by bursts of test-bed change. This seems
to be much less disruptive than a constant rippling and trembling.

| | | #2627 | | Conceptual integrity in turn dictates that the design must proceed from one
mind, or from a very small number of agreeing resonant minds.
- Frederick Brooks Jr., "The Mythical Man Month"
| | | #2628 | | It is a very humbling experience to make a multimillion-dollar mistake, but it
is also very memorable. I vividly recall the night we decided how to organize
the actual writing of external specifications for OS/360. The manager of
architecture, the manager of control program implementation, and I were
threshing out the plan, schedule, and division of responsibilities.
The architecture manager had 10 good men. He asserted that they could write
the specifications and do it right. It would take ten months, three more
than the schedule allowed.
The control program manager had 150 men. He asserted that they could prepare
the specifications, with the architecture team coordinating; it would be
well-done and practical, and he could do it on schedule. Futhermore, if
the architecture team did it, his 150 men would sit twiddling their thumbs
for ten months.
To this the architecture manager responded that if I gave the control program
team the responsibility, the result would not in fact be on time, but would
also be three months late, and of much lower quality. I did, and it was. He
was right on both counts. Moreover, the lack of conceptual integrity made
the system far more costly to build and change, and I would estimate that it
added a year to debugging time.

| | | #2629 | | The reason ESP, for example, is not considered a viable topic in contemoprary
psychology is simply that its investigation has not proven fruitful...After
more than 70 years of study, there still does not exist one example of an ESP
phenomenon that is replicable under controlled conditions. This simple but
basic scientific criterion has not been met despite dozens of studies conducted
over many decades...It is for this reason alone that the topic is now of little
interest to psychology...In short, there is no demonstrated phenomenon that
needs explanation.
-- Keith E. Stanovich, "How to Think Straight About Psychology", pp. 160-161
| | | #2630 | | The evolution of the human race will not be accomplished in the ten thousand
years of tame animals, but in the million years of wild animals, because man
is and will always be a wild animal.
