We underestimate risk of familiar activities and overestimate those of unfamiliar ones. Probability (some condition)= # of outcomes meeting the condition. Estimating risk: partly the job of science to obtain the data needed to estimate probabilities: dose-response curves from lab data. Test toxicology for example: acute toxicology (short-term response, chronic toxicology (long-term response, mutagenicity toxicology (cancers or mutations, teratogenicity toxicology (effects on developing embryo/fetus, hormonal activity (hormone blocking/mimicking)
