Current confidence in occupational health.

Little if any real justification is found for current apprehensions about health hazards in the work place. However, communications from some who are responsible for defining and controlling hazards tends to destroy confidence, rather than to build it up, as their knowledge and authority should obligate them to do. I attribute the unfortunate effect of their statements to confusion of association with cause and effect, reliance upon inappropriate experimental animal models, confusion of models with reality, irresponsible talk of conceivable possibilites rather than of realistic probabilities, and haste to announce suspicions before they can be confirmed or denied.
