Research Framework and Hypothesis Development: Investigating Cognitive Biases in Singaporean Workplace Decision-Making

This paper shows the research framework and hypothesis development for a quantitative study on heuristics andbiases in employee decision-making in Singaporean workplaces. The underlying theories used are the BoundedRationality and Prospect Theories. This study addresses research gaps previously identified by a systematic literaturereview (Ohms, 2025b), particularly focusing on non-investment contexts and Singapore. The study identifiesoverconfidence, herding, and decision avoidance biases as the independent variables; information evaluation,searching information, and procrastination as the dependent variables; and time pressure and complexity as themoderating variables. These hypotheses establish a rigorous theoretical foundation for investigating the specifiedrelationships, contributing to new knowledge in behavioural economics and organisational practice.
