HOW TO READ SCIENTIFIC DATA
On the average, not a single person would be misclassified by the HGN test
HOW TO READ SCIENTIFIC DATA On the average, not a single person would be misclassified by the HGN test Nevertheless, 37% of the sober individuals were classified as intoxicated under perfect laboratory conditions
Table 2 Good and Augsberger
HOW TO READ SCIENTIFIC DATA On the average, not a single person would be misclassified by the HGN test Nevertheless, 37% of the sober individuals were classified as intoxicated under perfect laboratory conditions In the field 83% of the sober individuals were classified as intoxicated
HOW TO READ SCIENTIFIC DATA In this, the most important of all the validations, 37% of the sober individuals were classified as intoxicated
HOW TO READ SCIENTIFIC DATA Finally, in the two sets of data from the latest (and presumably most definitive) study, Burns demonstrated that 79% of the HGN tests run on sober individuals under perfect laboratory conditions classified those individuals as being intoxicated
So, in conclusion, we can answer the question, “Are the SFSTs designed to fail?”
They are designed to fail if you hold to the belief that the law’s great purpose is to protect the innocent.”
For your future consideration: If you think the SFSTs are a disgrace to society, you will be appalled at the charlatans and fakers who try to sell you their “Drug Recognition Experts.”
