Here is an illustration of how you might go about doing the
“appeal to experts” assignment given in class. A couple of things
to note here: (1) You need not adopt any particular method of
bibliographic reference, but make it very easy for me to find the
original source, and cite it after every sentence in which you
refer to it. (2) It need not be pretty. It’s not an essay. Just
present the information as clearly as you can.
ASSIGNMENT:
Some claim that creatures evolved from other forms of life. Is
this true?
Answer this question by constructing an appeal to experts argument
that meets all of
the criteria given in class. Document your findings as follows:
1. State what profession(s) have the relevant expertise on the
issue.
2. Present two sources to support your conclusion about whether
creatures evolved from other forms of life. Use at least two of
the four methods given in class (i.e., a literature review in a
professional journal, a textbook, a large professional
organization, a poll of experts). You must include a readable pdf
or scan of the page on which you have highlighted the passage
where your source indicates the consensus view on the topic. Be
sure to include full bibliographic information for each of your
sources including a URL if available.
3. For each source, document how it meets the criteria for that
kind of source given in class. For example, for a professional
journal, explain how you know it is a professional journal using
the criteria given in class; for a professional organization,
describe its membership; etc.
4. Finally, explain how your argument meets each of the three
criteria for an appeal to experts argument.
ANSWER:
The conclusion of this argument is that creatures evolved from
other forms of life.
1. The relevant experts are biologists, including botanists and
some anthropologists.
2. Two sources in support of this claim are:
(A) FASEB, "FASEB opposes using science classes to teach
intelligent design, creationism, and other non-scientific
beliefs," The FASEB Journal, Vol. 20, Issue 3, March 2006,
p. 408.
The Federation of American Societies for Experimental Biology
(FASEB) published an official statement that reads, in part,
“While there may be some disagreement about the details of
evolution, it is not a controversial theory among scientists.
Rather, there is overwhelming scientific consensus that evolution
is a valid explanation for the development of species”
(http://www.fasebj.org/content/20/3/408.full).
(B) Gregory C. Mayer, Professor in the Department of Biological
Sciences, U. of Wisconsin-Parkside, "The Evidence For
Evolution," The Princeton Guide
to Evolution, ed. by Jonathan B. Losos (Princeton
University Press, 2014), p. 38:
"As briefly reviewed here, all these lines of evidence, all
leading to the same conclusion, serve to make descent with
modification one of the most securely established high-level
generalizations in science and allow us to speak confidently of
the fact of evolution".
[Attach paper copies of your sources with the relevant sentence or
two highlighted.]
3. How I know that each source is appropriate for an appeal to
experts:
For source (A):
FASEB is an organization of the relevant experts listed above
(biologists, etc.). FASEB represents 22 professional societies and
84,000 scientists (as stated on their web page at
http://www.fasebj.org/content/20/3/408.full).
For source (B):
The Princeton University Press is an academic press that publishes
scholarly, peer-reviewed books, as stated on their website at:
https://press.princeton.edu/about_pup/mission.html.
4. How my argument meets each of the three criteria for appeal to
experts arguments:
The first criterion was that there must be an appeal to experts in
the relevant field(s). Both sources appeal to biology professors
and others with relevant expertise regarding evolution. Mayer is a
professor of biology describing the consensus of evidence.
The second criterion was that there must be a consensus among the
experts in the field. Both sources indicate that the vast majority
of experts in the field agree that evolution occurred.
The third criterion was that the experts be honest, sincere, and
relatively unbiased. While a few of those polled in the larger
surveys might well be dishonest or biased, it would be
unreasonable to believe that such large numbers of experts are all
lying for the sake of some ulterior motive. Such conspiracy
theories are unlikely to be true.
I conclude that the above appeal to experts is a strong argument,
and thus that it is likely true that evolution occurred.
