 A procedures supplementary to observation in which the researcher seeks to test the authenticity of the reports or observations made by others.

The historical method is employed by researchers who are interested in reporting events and/or conditions that occurred in the past. An attempt is made to establish facts in order to arrive at conclusions concerning past events or predict future events.

Steps to Follow

Isolate the problem
Collect source materials, including primary and secondary sources
Evaluate source material
Formulate hypotheses
Report and interpret findings

Primary Sources of Information - Direct outcomes of events or the records of eyewitnesses

Original documents

Secondary Sources of Information - Information provided by a person who did not directly observe the event, object, or condition

Review of research and other references

External Criticism - Asks if the evidence under consideration is authentic. The researcher checks the genuineness or validity of the source. Is it what it appears or claims to be? Is it admissible as evidence?

Internal Criticism - After the source is authenticated, it asks if the source is accurate, was the writer or creator competent, honest, and unbiased? How long after the event happened until it was reported? Does the witness agree with other witnesses?


Establishing the Genuineness of a Document of Relic

Does the language and writing style conform to the period in question and is it typical of other work done by the author?
Is there evidence that the author exhibits ignorance of things or events that man of his training and time should have known?
Did he report about things, events, or places that could not have been known during that period?
Has the original manuscript been altered either intentionally or unintentionally by copying?
Is the document an original draft or a copy? If it is a copy, was it reproduced in the exact words of the original?
If manuscript is undated or the author unknown, are there any clues internally as to its origin?


Checking the Content of a Source of Information

What was meant by the author by each word and statement?
How much credibility can the author’s statements be given?



Statement of hypotheses
External and internal criticism of sources
Observation and experimentation
Technical terminology
Generalization and prediction



The research is not physically involved in the situation under study.
No danger of experimenter-subject interaction.
Documents are located by the researcher, data is gathered, and conclusions are drawn out of sight.
