  • Causation and Hill’s Criteria
    Causation is not so simple to determine as one would think. A mantra at SBM is ‘association is not causation’ and much of the belief in the efficacy of a variety of quack nostrums occurs because improvement occurs after use of a nostrum, therefore improvement occurs because of use of a nostrum. It is why vaccines as a cause of autism are so compelling to some. Vaccines are given at the same time autism starts to manifest. It would require more intellectual power than I have not to conclude, wrongly, that vaccines caused the autism. Concluding causation from sequential events is how the human mind works, and reality, as we know and ignore, constantly conspires to fool us into making false causal connections. In Infectious Diseases I see the error almost daily. The patient had a fever, patient was given antibiotics, fever went away. Therefore the antibiotics treated an infection. Well, maybe, maybe not. One of my mantras is ‘antibiotics are not antipyretics’ and you must be very careful before concluding that the fever went away because of the penacephalone.
