Selected instances and Suppressed
evidence (similar to card stacking). Any attempt to keep people
from gaining access to all the relevant material that they
need to arrive at the correct conclusion. Only offering information
which makes one's position look good, or information that makes
the opposition look bad. |
Important evidence which would undermine an inductive argument
is excluded from consideration. The requirement that all relevant
information be included is called the "principle of total evidence".
(i) Jones is Albertan, and most Albertans vote Tory, so Jones
will probably vote Tory. (The information left out is that Jones
lives in Edmonton, and that most people in Edmonton vote Liberal
or N.D.P.)
(ii) The Athletics will probably win this game because they've
won nine out of their last ten. (Eight of the Athletics wins came
over last place teams, and today they are playing the first place
team.)
(iii) The theory of evolution, as generally presented, relies
on selected instances AND suppressed evidence. A large body of
evidence undermines the theory,
yet this is rarely presented. Only that evidence which puts the
theory in a good light is presented. The picture below is commonly
shown in textbooks and in museums. Unfortunately, every supposed "link" has
been shown to be either faked or a monkey of some sort, or a modern
man of some sort. While some of these have been shown not to be
links decades ago, this information is not presented.
Give the missing evidence and show that it changes the outcome
of the inductive argument.
