Principle of least effort

The principle of least effort is a broad

principle of least action or other articles listed below
).

This is perhaps best known, or at least documented, among researchers in the field of library and information science. Their principle states that an information-seeking client will tend to use the most convenient search method in the least exacting mode available. Information-seeking behavior stops as soon as minimally acceptable results are found. This theory holds true regardless of the user's proficiency as a searcher, or their level of subject expertise. Also, this theory takes into account the user's previous information-seeking experience. The user will use the tools that are most familiar and easy to use that find results. The principle of least effort is known as a "deterministic description of human behavior".[1]

The principle of least effort applies not only in the library context, but also to any information-seeking activity. For example, one might consult a generalist co-worker down the hall rather than a specialist in another building, so long as the generalist's answers were within the threshold of acceptability.

The principle of least effort is analogous to the path of least resistance.

History

The principle was first articulated by the Italian philosopher

Zipf's Law.[3]

Within the context of information seeking, the principle of least effort was studied by Herbert Poole who wrote Theories of the Middle Range in 1985.[4] Librarian Thomas Mann lists the principle of least effort as one of several principles guiding information seeking behavior in his 1987 book, A Guide to Library Research Methods.[5]

Likewise, one of the most common measures of information seeking behavior, library circulation statistics, also follows the

80-20 rule. This suggests that information seeking behavior is a manifestation not of a normal distribution curve, but a power law
curve.

Applications

The principle of least effort is especially important when considering design for libraries and research in the context of the modern library. Libraries must take into consideration the user's desire to find information quickly and easily. The principle must be considered when designing individual

Online Public Access Catalogs (OPACs)
as well as other library tools.

The principle is a guiding force for the push to provide access to

Texas A&M distance learning graduate students to test what library resources they used, and why they used those particular resources. In this study the Internet was used the most, while libraries were the next most used resource for conducting class research. The study found that most students used these resources due to their quickness and ability to access from home. The study found that the principle of least effort was the primary behavior model of most distance learning students.[6]
This means that modern libraries, especially academic libraries, need to analyze their electronic databases in order to successfully cater to the needs of the changing realities of information science.

Professional writers employ the principle of least effort during audience analysis. The writer analyzes the reader's environment, previous knowledge, and other similar information which the reader may already know. In technical writing, recursive organization, where parts resemble the organization of the whole, helps readers find their way. Consistency of navigational features is a common concern in software design.
