HOW TO READ SCIENTIFIC DATA

HOW TO READ SCIENTIFIC DATA • On the average, not a single person would be
misclassified by the HGN test
![Page 19: Oklahoma Criminal Defense Lawyers Association 2012 Patrick A. Williams Criminal Defense Institute June 28, 2012.](https://reader036.fdocuments.net/reader036/viewer/2022062320/56649c8a5503460f94943d0a/html5/thumbnails/19.jpg)

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
![Page 21: Oklahoma Criminal Defense Lawyers Association 2012 Patrick A. Williams Criminal Defense Institute June 28, 2012.](https://reader036.fdocuments.net/reader036/viewer/2022062320/56649c8a5503460f94943d0a/html5/thumbnails/21.jpg)
• 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
![Page 23: Oklahoma Criminal Defense Lawyers Association 2012 Patrick A. Williams Criminal Defense Institute June 28, 2012.](https://reader036.fdocuments.net/reader036/viewer/2022062320/56649c8a5503460f94943d0a/html5/thumbnails/23.jpg)

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?”
![Page 29: Oklahoma Criminal Defense Lawyers Association 2012 Patrick A. Williams Criminal Defense Institute June 28, 2012.](https://reader036.fdocuments.net/reader036/viewer/2022062320/56649c8a5503460f94943d0a/html5/thumbnails/29.jpg)
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 disgraceto society, you will be appalled at the charlatans and fakers who try to sell
you their “Drug Recognition Experts.”
