Seeking positive experiences can produce illusory correlations.

Area of Science:

• Cognitive Psychology
• Decision Science
• Social Psychology

Background:

• Individuals often exhibit a preference for options associated with positive impressions and avoidance of those with negative ones.
• Previous explanations for illusory correlations often involve biased information processing or selective attention.

Purpose of the Study:

• To demonstrate how sequential sampling in information acquisition can lead to illusory correlations between multi-attribute alternatives.
• To propose an alternative theoretical framework for understanding illusory correlations.

Main Methods:

• The study models the sequential sampling process of information acquisition.
• It analyzes how decision-makers combine attribute estimates when making sampling choices.
• The research explores different evaluation strategies (compensatory, disjunctive, conjunctive).

Main Results:

• Sequential sampling inherently generates illusory correlations between estimated attributes.
• The direction of the illusory correlation (positive or negative) depends on the decision-maker's attribute evaluation strategy.
• Positive correlations emerge with compensatory or disjunctive evaluations; negative correlations arise with conjunctive evaluations.

Conclusions:

• The proposed theory offers a novel explanation for illusory correlations, independent of biased processing or selective attention.
• This framework provides new insights into phenomena like the Halo effect, proximity-attitude relationships, and in-group/out-group biases.
