Proportion of Suicide Note Formats: Computer Files Account for 2.1%

‌A study by researchers from the National Forensic Service and Seoul National University, published in the Journal of the Korean Society of Legal Medicine in 2014, investigated cases confirmed as suicides that were referred to the NFS for autopsy between February 2012 and August 2013. Initially, 55 suicide note authors were identified; after excluding 7 cases where only investigative records remained, 146 actual notes from 48 individuals were analyzed. The paper explicitly states regarding the medium used: **“With the exception of one deceased individual who wrote a suicide note as a computer document, all others wrote by hand on paper.”** Therefore, calculating based on the number of people, **computer-written is 1/48 = approximately 2.1%, and handwritten on paper is 47/48 = approximately 97.9%.**
In other words, the rate of leaving a suicide note via computer is 2.1% (1 out of 48 cases).
Furthermore, the probability of a 62-year-old male, who was not accustomed to computers in 2009, leaving a suicide note via computer would be much lower than this, wouldn't it?
