Using Mental Models to Improve Understanding of Cattle Diseases.

Abstract

Throughout history, theories of disease etiology have evolved. These theories of disease etiology, which can also be considered mental models of disease, have been based on associations drawn from careful observation of diseased and healthy individuals. Mental models of disease, even when incorrect, have frequently reflected real associations between proposed exposures and disease even when the exposures eventually were disproved as causal. The same patterns can be observed in mental models of disease in cattle. Throughout time, mental models for common bovine diseases have been improved to better reflect how disease actually occurs. It is important to recognize that inconsistencies still exist between observation of actual disease and our understanding of disease etiology. These inconsistencies can be viewed as opportunities for further discovery to improve our understanding of disease. Future progress in controlling bovine diseases depends on converting these opportunities into better mental models of disease.
