Objective = physical
Subjective = feeling

a. Your are more disappointed when you lose €500 than happy when you
gain €500
2. Our risk propensity if determined by how options are framed
3. People evaluate the consequences in terms of deviation from a reference
point (individuals status quo)
a. Compared to others around people (reference point) x=0 y=0 in graph
4. People experience diminished sensitivity to losses and gains
People become
- Risk averse when they can gain something (gain frame)
- Risk seeking when they can lose less (loss frame)
Reference points change constantly
