What is prospect theory in international relations?

Prospect theory posits that when individuals perceive themselves to be experiencing losses at the time they make a decision, and when their probability estimates associated with their principal policy options are in the moderate to high range, they will tend to make excessively risky, non-value-maximizing choices.

Why is prospect theory important in international relations?

The theory describes how individuals evaluate and choose between available options, and is used to explain why people consistently deviate from the predictions of rational choice. The most commonly utilized finding of prospect theory in the international relations literature is the so-called framing effect.

Why is prospect theory important?

Prospect theory is important because it explains how we understand and value gains and losses differently, and therefore how we make economic decisions. Prospect theory can also help us understand how best to present options to others.

What are the implications of prospect theory?

The most famous implication of prospect theory is loss aversion—not the trivial point that we do not like losses, but that losses inflict psychological harm to a greater degree than gains gratify, which means that people are more willing to run risks to avoid or recoup losses than to make gains.

What are the applications of prospect theory?

While most applications of prospect theory to political science have focused on loss aversion, framing, and the reflection effect, another im- portant observed anomaly in expected-utility theory is that individuals tend to respond to probabilities in a non-linear fashion.
