In the first post in this series, I looked at the work of Swedish psychiatrist Lars Thorell, who has developed a test which, he claims, is able to predict suicides in depressed patients. Thorell's test is called electrodermal orientation reactivity (aka electrodermal hyporeactivity), and while Thorell's work on the technique goes back to the 1980s, it has recently been commercialized by a company called Emotra AB, who named the product EDOR®.
