In order to test for reliability,
these are some of the questions an historian should ask.
Who wrote the source?
- What are
their ideas / beliefs?
- What is
the extent of their knowledge of the subject
- Are they
well informed or is their work over opinionated?
- Are there
many "I" statements in the work, or is it written
in the "third person".
- Are they
for or against the issue under discussion?
Is the source a
Primary Source?
- Is the author
an eyewitness?
- Eyewitnesses
may lack a global view, they may not be able to see/hear all that
happened
- However,
they will be able to present a focussed point of view
- Was the source
written for a specific reason, eg. a private diary may present
the same material quite differently from a witness statement given
to a government inquiry.
- As an immediate report,
it could contain errors
- An eyewitness report
can be very valuable for feelings and details which may not "make
it" in later versions.
Is the Source a
Secondary source?
- It could
have the benefit of hindsight. That means the researcher knows
the outcome.
- It is based
on primary sources. Researcher may have been careful to select
from sources which "corroborate", ie. bear each other
out
- Researcher
should have been able to check the facts to ensure there are
no errors in fact.
Why was the source
written?
This may well have
effect on the treatment of the subject by its author.
- Was it
written for publication - ie. the author was paid to write it?
- Was it
written for a newspaper or a professional /educational journal?
This will affect the way and the depth in which the subject
is presented
- Was it
written for official purposes, as part of a government inquiry,
or for a Council, etc.
- Was it
written for private use? Again, a letter and a diary may present
the same information quite differently.
Who was the intended
audience?
- Was it
written for the general public with a limited knowledge of the
subject, eg. a newspaper
- Was it
written for people who knew a little about the subject - eg.
a text book
- or people
who were experts in the subject area?
- Was it
written by a member of the group for the same group?
How was the language
selected?
- The choice
of words may place bias on the material.
- Is it
emotive or factual?
- Are there
many "I" statements?
What about the selection
of facts?
- Does it seem
to be a fair account, or is only one side presented?
- What 'silences'
or gaps exist in the information?
Remember, what
is not said if often more important than what is said
Are there errors
in fact?
- This may
indicate an unreliable source.
When sources do
not agree ….
- As a starting
point, check the areas or points where they do agree.
- Seek further
for what is called "corroborating evidence". This is material
which either confirms or denies your source.
- Check the
"reliability" of the author/s - did their contemporaries hold
them in respect for their fair judgment?
