If you have the time, you have the talent. How individuals approach risk is subject to great cultural and psychological variation. Concerning one aspect of uncertainty, Colin Powell said he made decisions when between 40 and 70 percent of the information or evidence was available. Less than 40 percent was not enough evidence, and waiting for more than 70 percent would normally delay a decision until too late. The makers of microwave ovens shrewdly have not talked in terms of microwaves being radiation.
Risk assessment assumes rationality, but some otherwise rational people drive while drunk.
In your community you may be faced with the role individual decisions play within collective decisions. An example may be drawn from a play by Henrik Ibsen, An Enemy of the People, written in 1882. This story is about the possibility of contamination of the water supply for a town's new mineral baths. The baths attract summer visitors that are important to the economic base of the community. Before construction began, a local doctor warned the town fathers about potential contamination of the water supply, a warning that went unheeded.
