,Lecture 1. Introduction and Risk society
Why good risk communication matters:
Third-generation oral contraceptive pills increase the risk of potentially life-threatening blood clots
in the legs or lungs twofold – that is, by 100%.
Vs.
Third-generation oral contraceptive pills increase the risk of potentially life-threatening blood clots
in the legs or lungs from 1 in 7000 women, to 2 in 7000 women.
There are multiple definitions of risks however they are overlapping.
Risk= the likelihood of an unwanted event (probability) and the magnitude of the consequences
(severity). Probability x Severity.
Risk vs. Hazard (gevaar): if you don't perform a particular act when there is a hazard, then a
particular risk will not be apparent. E.g. it is hazardous to stand walk on the edge of a building but
there is no risk if you just don't fall. The risk comes apparent when you take a misstep (the act).
Possibility vs. Probability:
Risk vs. Uncertainty.
Levels of uncertainty:
- First-order/aleatory uncertainty: things we can't know.
- Second-order/epistemic uncertainty: things we don't know.
Uncertainty are limitations in calculating the risks. There are always limitations in the mathematical
models because there are always predictors/mediators that cannot be calculated.
There are known knowns: things we know that we know. There are also known unknows: things that
we know we don't know. And there are unknowns: things we do not know we don't know.
Risk communication= the interactive process of exchange of knowledge, perceptions, attitude, and
opinions related to risks between individuals, groups, and institutions.
The model of communication:
, Sociological notion describes the societal context in which we currently live as a risk society: the
management of all risks citizens may run. The welfare state brought prosperity and process, but now
this progress may turn against us: nuclear weapons, food consumption and obesity, health impact
and social impact of screen time, etc. Risks are socially constructed.
Welfare state= a system of government that actively promotes the well-being and social security of
its citizens through the provision of various social services, benefits, and economic interventions.
1st stage of modernization: industrial modernity
- Production of material wealth/goods
- The avoidance of scarcity
- Control over nature
- Risks are temporarily and physically bound
- Risks are direct, visible, and fixable
- Started with enlightenment
2nd stage of modernization: reflexive modernity/risk society
- Production of safety and knowledge
- The avoidance of risk
- The preservation of nature
- Dynamic and enduring global risks
- Risks are mediated, invisible and irreversible
- Started at the end of the cold war
VUCA world:
Volatility (wisselvalligheid)= a fancy word for change
Uncertainty= able to plan on the risk (e.g. covid)
Complexity= multiple causes, how many stakeholders are involved? (e.g. covid)
Ambiguity (meerduidigheid)= maybe not knowing what causes the risk
