- Anchoring and adjustment
- (these are the qualitative aspects of risk)
What is representativeness in risk assessment including cons?
- Part of qualitative decision making in the face of uncertainty
- Places likelihood of object in general class
- Cons: leads people to pay too much attention to specific details (engineer example)
- Cons 2: people are insensitive to sample size (hospital female baby births)
What is availability in risk assessment?
- Part of qualitative assessment includes:
- -Ease of recall similar events (old people and heat attacks; young people car accidents;

What is the biological basis of irrational risk perception?
- - only organisms that could recognize and respond to danger survived and evolved
- - our brain is designed for fear first and then think
What are some general rules to risk perception?
- - perception factors are like seesaws
- - several factors are usually involved; importance varies over time
- - factors are universal across cultures, ages, and gender
In risk perception, what is control and what makes people more or less afraid?
- - Control is imposed or voluntary risk factors – CHOICE

Why does most risk communication fail?
- - doesn’t account for the psychological basis for perception of risk
- - refuses to accept irrational behavior is how ppl are programmed
- - has counterproductive goal of making everyone see the risk as communicator sees it
How can risk communication be more successful?
- - accept that people react emotionally
- - provide info about risk based on psychological/emotional factors
Why does risk perception matter?
- - we make decisions about risk every day
