Son yıllarda finans alanında ilgi gören aşırı öz güven algı sapmasının hem amprik hem de deneysel yaklaşımlarla incelendiği görülmektedir. İkincil veri kullanan ampirik çalışmaların dezavantajı ise aşırı öz güven algı sapmasının piyasalarda doğrudan gözlemlenemiyor olmasıdır. Bu nedenle, amprik çalışmalarda aşırı öz güven algı sapmasını temsil edeceği düşünülen çeşitli değişkenler kullanımakta ancak bu durum yanıltıcı sonuçlar ortaya çıkarabilmektedir. Bu kapsamda, deneysel çalışmaların değişkenlerin kontrol altına alınabildiği laboratuvar ortamında yapılıyor olması nedeniyle, aşırı öz güven algı * This paper is based on Ph.D. thesis of Serkan SAHIN, completed at the Middle East Technical University. * Arş. Gör. Dr., Kahramanmaraş Sütçü İmam Üniversitesi, İİBF, İşletme Bölümü, Kahramanmaraş, serkansans@hotmail.com. ** Prof. Dr., Orta Doğu Teknik Üniversitesi, İİBF, İşletme Bölümü, Ankara, yozlem@metu.edu.tr. sapması doğrudan ortaya konulabilmektedir. Bu çalışmanın amacı İngiltere’deki bireylerin genel ve finansal güven düzeylerini ölçümlemek ve aşırı özgüven sapmasının farklı alanlara bağımlı değişen bir yapısı olup olmadığını belirmektir. Elde edilen bulgular bireylerin genellikle sahip oldukları bilgilere aşırı güven duyduklarını göstermiştir. Çoğu birey kendini diğer katılımcılardan bilgi ve beceri olarak üstün görmekte ve hisse senedi piyaslarında üstün başarı elde edeceklerini düşünmektedirler. Ayrıca elde edilen bulgular bireylerin yatırım bilgisi gerektiren konularda kendilerine daha az güvendiğini ortaya koymaktadır.
