of information overload‚ individuals use heuristics. What are heuristics? Heuristics are strategies which reduce the complex tasks of assessing probabilities and predicting values to simpler judgmental operations (Tversky & Kahneman‚ 1974).

Therefore‚ heuristics use principles of effort-reduction and simplification
