Prospect theory explains several biases that people rely on when making decisions. For example, Nathan Berg and Gerd Gigerenzer claim that neither classical economics nor prospect theory provide Kahnemans Prospect Theory Analysis convincing explanation of how people actually make decisions.

Prospect Theory: An Overview
This conventional model however, notably ignores the heuristics and the psychological biases which may warp the decision making process. Among these biases are loss aversion, risk preferences and framing which can significantly shape the bargaining outcomes. While skillful lawyering may ameliorate some biases, evidence suggests that the impact of framing remains a crucial component in the process. The participant pool for this experiment comprised experimental economists, a group which one might perceive to be cognizant of, and therefore, resistant to the framing effect. The experiment was administered during the runup to a conference the participants were to attend. The first group was presented the information concerning the difference between early and late payment fees in a positive frame as a discount.
The second group was given the same information in a negative frame as a late penalty. The results indicated that while the junior experimental economists were influenced by the framing effect, the more senior economists were not. A research study by James Druckman of the University of Minnesota sought to investigate how framing effects may be reduced or overcome Druckman, Druckman utilized two experiments to demonstrate the role of advice on how individuals should decide when various options are offered.
The first experiment used a variation of the experiment of Kahneman and Tversky described above: choosing a hypothetical treatment for people with a fatal disease. The second experiment presented the participants a hypothetical choice between surgery and radiation to treat lung cancer, along with a recommendation from specialists from two prominent medical research organizations on which option to choose. Results from both the experiments seem to indicate that recommendation or endorsement from a supposedly credible source could dramatically decrease or even eliminate the framing effect.
A merely intuitive approach might suggest that the framing effect remains constant despite the language, or perhaps that the difficulty associated with a foreign tongue may in fact amplify the framing effect because the challenges in comprehension could make the decision-making process less systematic. However, research demonstrates that employing a foreign language actually reduces decision-making biases. Results from 4 experiments showed that when various options for choice were presented to the participants in their native tongue, they were risk seeking for losses and risk averse for gains.
However, when the same options were offered in a foreign tongue the participants were immune to this framing manipulation. This outcome suggests that the framing effect vanishes when the choices are presented in a foreign language. Two additional experiments demonstrated that employing a foreign language could increase the acceptance of real and hypothetical bets with positive expected value by reducing loss aversion.
The greater emotional and cognitive distance afforded by a foreign language seems to account for these outcomes. For instance, while preschoolers tend to base their decisions on quantitative properties like the probability of a certain result, elementary schoolers tend to rely on qualitative reasoning, choosing surer options for gains within a positive frame, and riskier options within a negative frame notwithstanding the probability.
This diminishes the influence of the framing effect and induces more consistency between positive and negative frames. Moreover, research suggests that undergraduate students are more willing to buy an item after losing an equivalent amount of money rather than the item itself. As such, they are more likely to depend upon readily accessible information and even frames. For instance, research shows that the decision-making of older adults on medical issues is shaped more by how doctors frame the available options than the actual difference between such options. Moreover, when choosing cancer treatments, framing may shift their focus from short-term to long-term survival Erber, The discussion above, which unveils how the framing effect works, also points to us how it could be avoided.

Keysar, B. Thus, there will be deviations from the mean. For example, a subsample of individuals behaving in a consistently deviant fashion can help explain important aspects of choice behaviour, whether or not such behaviour is consistent with the conventional wisdom or prospect theory. Nevertheless, the underlying empirics of prospect theory with regard to average choice behaviour have been well documented.
As Tversky and Kahneman 50 write:. Although the properties of v and n summarize a common pattern of choice, they are not universal: the preferences of some individuals are not well described by an S-shaped value function and a consistent set of decision weights. However, it is defined over gains and losses around a reference point. The reference point is determined by the subjective feelings of the individual. Value function is concave for gains and convex for losses. This means that value function is steeper for losses than for gains- this is referred as loss aversion. Three unique features of prospect theory:. Individuals tend to think in terms of gains and losses rather than a state of wealth. For example, if there are two people, one of them learns that his wealth has gone from 1 million to 1.
Most of the people will say that the first guy is happier. However if we look in terms of finance, the second person should be better pay off in terms of total wealth. The Prospect theory explains that people focus on the outcomes of their decisions. TheProspect Theory of Kahneman and Tversky follow value functions. Reference points serve to frame the decision parameters. Thus, gain and losses are evaluated both separately and relatively, as opposed to simultaneously and in terms of absolute values of state of wealth.This differs from expected utility theoryin which Kahnemans Prospect Theory Analysis rational agent is indifferent to the reference point.
