Technology dominance, theory of

Acronym
TTD

Alternate name(s)
Not applicable

Main dependent construct(s)/factor(s)
TTD has two dependent factors:


 * 1) Reliance - The extent to which and individual applies the intelligent decision aid and integrates the recommendations of that aid into his or her judgment.
 * 2) Dominance - The state of decision making where the intelligent decision aid, as opposed to its user, takes primary control of a decision making process.

Main independent construct(s)/factor(s)
TTD has four independent factors:


 * 1) Task Experience - The level of experience a decision maker has regarding the completion of a task as well as the extent to which the decision maker has developed strategies for completing that particular task.
 * 2) Task Complexity - The extent to which the cognitive abilities of the decision maker are challenged with completing a certain task. (In psychology this is often termed Task Difficulty.)
 * 3) Decision Aid Familiarity - The extent to which the decision maker is comfortable with the intelligent decision aid based on prior experience and/or significant training with the aid (or similar aids).
 * 4) Cognitive Fit – The extent to which the cognitive processes used with the decision aid to complete a task match the cognitive processes normally applied by the decision maker using the aid.

Concise description of theory
The Theory of Technology Dominance (TTD) posits that a decision maker may become reliant on an intelligent decision aid under two conditions:


 * 1) The decision maker is low in task experience (see independent factors).
 * 2) The decision maker is high in all factors (task experience, task complexity, decision aid familiarity, and cognitive fit).

According to TDD, reliance on an intelligent decision aid can create a long-term, de-skilling effect in the user as well as hinder that user’s growth of knowledge and advancement in his or her domain. Furthermore, TDD states that a negative relationship exists between the user’s expertise level and the risk of poor decision making when the expertise of the user and intelligent decision aid are mismatched. When the expertise of the user and the aid are matched, however, a positive relationship exists between reliance on the aid and improved decisions making.

Conceptually, TTD can be divided into three sections which are built on a total of eight testable propositions. The three sections are:


 * Section 1: Addresses the factors that determine the likelihood that a decision maker will rely on an intelligent decision aid.


 * Section 2: Addresses the conditions under which a decision maker is vulnerable to being dominated by the intelligent decision aid.


 * Section 3: Addresses the long-term impact of intelligent decision aid use on de-skilling domain experts and impeding epistemological evolution.

The eight testable propositions are (Arnold & Sutton, 1998):


 * Section 1 - Factors influencing reliance
 * Proposition 1: “When users have a low to moderate level of experience, there is a negative relationship between task  experience and reliance on a decision aid."
 * Proposition 2: “There is a positive relationship between task complexity and reliance on a decision aid.”
 * Proposition 3: “When task experience and perceived task complexity are high, there is a positive relationship between decision aid familiarity and reliance on the decision aid.”
 * Proposition 4: “When task experience and perceived task complexity are high, there is a positive relationship between    cognitive  fit and reliance on the decision aid."


 * Section 2 – Conditions favorable for dominance
 * Proposition 5: “When the expertise of the user and intelligent decision aid are mismatched, there is a negative relationship between the user’s expertise level and the risk of poor decision making."
 * Proposition 6: “When the expertise level of the user and intelligent decision aid are matched, there is a positive relationship between reliance on the aid and improved decisions making."


 * Section 3 – Long-term effects
 * Proposition 7: “There is a positive relationship between continued use of an intelligent decision aid and the de-skilling of auditors’ abilities for the domain in which the aid is used."
 * Proposition 8: “There is negative relationship between the broad-based, long-term use of an intelligent decision aid in a given problem domain and the growth in knowledge and advancement of the domain.”
