This is a consequence of the informal, intuitive methods used by its practitioners to discover patterns with predictive power. As a discipline, TA suffers because it is practiced without discipline.

Adopting a rigorous scientific approach would solve this problem. The scientific method is not a cookbook procedure that automates knowledge discovery. Rather it is “a set of methods designed to describe and interpret observed or inferred phenomena, past or present aimed at building a testable body of knowledge open to rejection or confirmation.

The dramatic increase in our understanding of and control over the natural world over the last 400 years attests to the power ...
