The Robustness of Horizontal Gaze Nystagmus

Posted On April 06, 2008 by Charles Ramsay

The author of this 2007 "Robustness" study claims that the Horizontal Gaze Nystagmus (HGN) test is valid and reliable. However, her own statistics prove otherwise.

Scrutiny of the data in this study shows that even those with Alcohol Concentrations under .06 when administered "correctly" the HGN:

60% of people 0.059 and below had at least 4 out of 6 clues!

12% of people had all 6 clues!
