Görgü Tanıklarının Etkisi: Sosyal Bir İkilem Durumu Üzerine Oyun Teorisi Yaklaşımı

ÖzSosyal psikolojide “görgü tanıklarının etkisi” olarak ifade edilen sosyal ikilem, herhangi bir durumda mağdur konumundaki bir kişiye etrafındaki diğer kişilerin yardım etme ihtimalleri ile ilgilidir. Oyun teorisyenleri ve deneysel iktisatçılar tarafından bu sosyal ikilemin genel olarak gönüllülerin ikilemi ile aynı sosyal olguyu ifade ettiği varsayılmıştır. Bu makalenin amacı, farklı isimlerle anılan ancak aynı sosyal olguyu ifade ettiği tartışılan bu iki farklı ikilemi incelemektir. Makalenin temel sorusu “acaba bu iki sosyal ikilem, aynı sosyal olguyu mu temsil etmektedir?” şeklindedir. Çalışma öncelikle geniş bir literatür taraması verecek, ardından oyun teorik bir yaklaşım ile gönüllülerin ikileminin çözümünü ortaya koyacak ve son olarak görgü tanıklarının etkisi için alternatif bir teorik yaklaşım sunarak bu iki durumun benzer ve farklı yönlerini tartışacaktır.Anahtar Kelimeler: Davranışsal İktisat, Görgü Tanığı Etkisi, Gönüllünün İkilemi, Fedakârlık, Sosyal İkilem. 

The Bystanders’ Effect: A Game Theoretic Approach To One Social Dilemma Situation

AbstractIn social psychology, the bystander effect, defined as a social dilemma, is related to the probability of help to a victim by the mere presence of others. This dilemma has been generally assumed, by game theoreticians and experimental economists, to represent the same social phenomenon as the volunteer’s dilemma. In this paper, we analyze these two different social dilemmas and the main question of the article is whether these two different social dilemmas represent the same social state. We first provide a broad literature review, and discuss the game theoretical foundation of the volunteer’s dilemma. Then, we provide an alternative theoretical explanation for the bystander effect and discuss the differences between these two social states.Keywords: Behavioral Economics, Bystander Effect, Volunteer's Dilemma, Altruism, Social Dilemma.
