필요성 및 목표
○ 필적감정 분야는 감정인의 주관적 관찰 및 판단이 감정결과로 도출되는 경우가 대부분이어서, 주관적 판단을 객관화시킬 수 있는 방법론 정립 또는 통계적 근거자료가 필요함
○ 필적감정의 통계화 및 일반인과 감정인의 감정 정확성 확인
방법 및 결과
○ 전문가 그룹과 일반인 그룹의 필적 감정 시행
○ 전문가 그룹의 경우 의견교환이 진행될수록 필적 감정의 오류율은 감소하고, 판단곤란율은 증가함
○ 일반인은 금전적 보상이 있으면, 판단곤란율이 감소하며, 오류율 증가함

Unlike printed letters, handwritten letters have various types depending on writers’ conditions and intentions, which makes it difficult to analyze scientifically.
Not only an individual’s natural handwriting, but also attempts to hide one’s own handwriting, and to copy anyone’s handwriting are the main targets in Forensic Science.
In this research, Korean handwritings were analyzed by 200 laypersons and 4 professionals(Forensic Handwriting Examiners, FHEs) through the medium of blind validation trials. The participants analyzed 180 questions that consisted of Long Handwriting, Short Handwriting and Name with Signature, also identified, different, simulated, and disguised handwriting against specimens.
In order to study changing trend of professionals’ opinion, professional group took peer-review(by 2 FHEs and 4 FHEs) after individual blind validation trials(by single FHEs).
On the other hand, in order to assure examiners’ attitude towards the experiment, half of laypeople were given incentives for accuracy of the analysis, while other half was not informed about it.
► Korean handwritings were analyzed by 200 laypersons and 4 Forensic Handwriting Examiners(FHEs) through the medium of blind validation trials.
► We found that the % misleading and % correct difference between FHEs and laypeople was significant.
► In the result of the professional group, the peer-review made inconclusive opinion much increasing, and misleading opinion decreasing.
► In the result of the laypeople groups, monetary incentives made inconclusive opinion decreasing, and misleading opinion increasing.
► This research was significant to show the first step toward Korean handwriting analysis and statistical experiment.
