the first thing to know that prejudice which means prejudgement is learned and it has negative consequences if not properly handles because it leads to discrimination and stereotypes. education is very key in terms of dealing with prejudice and also reorientation of the mind

Thanks Stanley. I understand that prejudice is learned behaviour, But I was also reading some research by Prof Paul Bloom of Yale Uni, saying that his research also argues that empathy and anxiety can be a natural biological response which he apparently tested with babies as young as 3 months. But I think it would be a hard push to say that prejudice is biological.

In this model, a switching equation sorts individuals over two different states (with one regime observed). The econometric problem of fitting a model with endogenous switching arises in a variety of settings in labor economics, the modeling of housing demand, and the modeling of markets in disequilibrium.

Social research often involves estimating the effects of a categorical treatment on a dependent outcome variable. Endogenous switching regression models are natural extensions of classical experimental designs, which allow tests of assumptions about the exogeneity of treatment effects from survey data.
