In general humans have a tendency to make haste decisions or form opinions based on the demographic, appearance, past actions etc. of a person. These behaviours are formed from childhood based on our experiences growing up, and social stigmas which have been passed down generations . For example, people with tattoos and piercings are often associated with negative stigmas. I don’t understand this because everybody should have the freedom to express themselves in anyway they want. The same applies to judgments when it comes to clothing and style.
Our generalization of certain people also stems from our instinct to be protective of our self and others . For instance, normally a person with a criminal past wouldn’t easily be given a second chance .
Another type of generalization that people make is forming an expectation based on previous experiences . For example, a teacher who has a negative experience with a student might expect the same from their sibling, if they land up teaching them. Another popular tendency that is similar is when people assume all east asians get good grades .
In my opinion we need to start being more open minded rather than judging or forming rapid assumptions about people because of who they are, where they come from and their demographic.
