Yes, but before posting on here I always had that ability to seize people quickly and process their mental quirks, personality tendencies based on their body language, eye movement etc. I am ruthless when it comes to analyze individuals/groups. Its partly inherent

in me but I love to read so in that case, reading countless psychology books helped me to sharpen my people reading skills.
As for

people, its tricky because were I live

tendencies are not overt, they are very well hidden but its extremely slick/subtle, definitely noticeable, if you train yourself to read people, situations, etc. They are not about that open racism life so nikkas here have to be 10x racially/socially aware. I know how to pay attention on very small details, so no problem for me.
