People who are prejudiced feel a much stronger need to make quick and firm judgments and decisions in order to reduce ambiguity. “Of course, everyone has to make decisions, but some people really hate uncertainty and therefore quickly rely on the most obvious information, often the first information they come across, to reduce it” Roets says. That’s also why they favor authorities and social norms which make it easier to make decisions. Then, once they’ve made up their mind, they stick to it. “If you provide information that contradicts their decision, they just ignore it.”
I can see from this article that there is no way to change the fundamental way of the human mind. I think that humans should try their best to not categories others into groups , even if they do they should not be so quick to judge , as the saying goes “do not judge a book by its cover” and instead inquire and observe more before making negative justification towards that group . This is most likely the cause of racism, where because of one person; the whole race is despised and thought ill off, when the rest are fine and easy to get along with. I wonder when will humans ever bond as one and no longer be biased towards anything.
