A few months ago I took Lance Platt’s SFST certification course for attorneys. We had mostly defense lawyers and some prosecutors in the room. I didn’t come into this with clean hands. My experience with DWI cases and research of these “tests” tells me they are voodoo bullshit.
I came to this conclusion because as I understood the SFST studies they lacked the markers of real science and quality research; control groups, blind studies, placebos etc. Did you know the field sobriety tests have never been tested on a large groups of individuals who have not been drinking? Or on individuals with different medical conditions? There have been exactly zero studies on gender differences, or on the effect of performing the tests under the stress to mimic the pressure of a typical roadside DWI investigation. Why?
SFST’s are agenda driven science. The feds needed a way to arrest people who had been drinking, but without any bad or impaired driving behavior. So they invented the notion that by performing 10 minutes of balancing tests you can tell if someone is over .08.
