Because generalizing from past experiences and information available is useful. and helps you make decisions. I think it’s not possible to say you or anyone else do no look at someone and make instant judgments, our brain is evolved to to do this for survival. If you found a way to turn this off, let me know. The only problem is if you do not make adjustments to new information given.
Consider the following scenarios.
I am the captain picking players for my basketball team. For my first pick I see three guys of which i’ve never seen play. One is a 6’8 black guy who has giant python arms with veins popping out wearing michael jordan shoes. 2nd is a 5’8 man of hispanic background with a Cristiano Rolando jersey on. 3rd is a 5’10 white guy with skater shoes. Are you going to really not make prejudgments based on their physical appearance, clothes they picked to wear or the sake of possibly making them not feel like a birthday boy. Maybe the 6’8 black is terrible at basketball and likes to play pokemon card games and the mexican man actually hates soccer but his grandma gave him that shirt today for his brithday and he wore it to make her happy. But all the previous experiences tell me the 6’8 black guy wearing Jordan basketball shoes is probably going to be good at basketball. Now if I watch all 3 play and see it’s actually the skater guy thats the best and I still won’t believe at the 6’8 black guy is bad at basketball and a white guy can play, yeah that would be stupid.
What if i’m a police officer looking for a chinese triad group who recently robbed a bank in my area. Do I somehow find a way to turn off all my pre judgements and not spend most of my time looking for people who might be in the Chinese triad…which would be chinese people because of the fear of prejudgments and making the person not feel great? I don’t think so. It would only be stupid to gather new evidence like the guy is actually korean and still be convince he is a Chinese triad member.
We are developed evolutionary to make judgements consciously and subconsciously. Animals make themselves big to make themselves seem more of a threat, we do the same. We read body language, facial expressions really well. We take in visual information and process them faster than any computer, and i doubt you are able to not do this.
So if i’ve gathered from my entire life that men and women generally are different in many ways from relationships, communication, temperament, behaviors, interests, personality, etc. And I don’t use this information along with the long list of psychological studies from men and women which can been observed as young as infants. I think that’s stupid. But people vary, it’s not like all men are exactly like one way and all women are exactly like one way. There are degrees of personality that everyone score differently on, but in general there is a difference between men and women and how their relationships are.
