Infallible laboratory pigeons
Trained laboratory pigeons are reported to produce excellent cancer detection rates when confronted with biopsy slides. 
Pigeons learn fast, in only 15 days, and manage to efficiently diagnose cancers, with accuracy levels close to 99%.
Even combinations of first and second opinions on pathology slides from expert pathologists with a high volume of diagnostic work resulted in many more mistakes in diagnoses. 
Pigeons err less than US pathologists.
False positive and false negative diagnostic results in this new study confirm doctors' inaccurate diagnostic performance.
