Second, uncertainty and surprises are unavoidable which makes expectations central to understanding economic decisions. Uncertainty refers to ignorance of the future and should not then be equated with risk assessment of uncertain but knowable futures. Different people have different histories and experiences and so expectations. This inherent variety adds heterogeneity and plural perspectives to economic agents.
