This is clearly in contradiction with the expected utility hypothesis in which a rational person is assumed to choose the option yielding the highest average payoff. Adding the influence of variance constitutes one of the main differences with the expected utility hypothesis for which variance is assumed not to influence the decision of a rational individual.
Their decision will wholly depend on the probabilities of the part of the game in which they are involved. When developing their theory, Kahneman and Tversky set out a framework which is still very useful to analyze the findings of behavioral finance.
First information is edited in order to simplify and quicken the second stage, the evaluation process. This clearly contradicts the Expected Utility Theory where all information is assumed to be evaluated in a rational and objective way. This is partly due to the fact that the cognitive task of analyzing all information equally is hardly possible. The result of this behavior is that investors simplify the information in order to evaluate it more easily. For example losing a concert ticket and losing the same value of the ticket but in cash leads to different choices. This is one reason why the followers of behavioral finance seriously doubt that individuals are able to distinguish properly between causal and empirical relationship.
