A person's physical characteristics often tell you a lot about that person. I'm not just talking about light skin or dark skin, which are useful traits to judge by of course. But even a group of white men, you can make reliable guesses about their personalities, physical abilities, mental capacities, and physical strengths from their faces alone.
And it's not that crazy of an idea, despite modern science telling you that phenotypes are Nazi science and easily (((debunked)))(critiqued by a jew).
For example, see the following images. You can probably guess with solid accuracy whether these men were involved in crime, or violent crime, or financial crime, etc. Humans have evolved for millions of years while developing basic heuristics of one another which may not be 100% accurate, but sufficiently accurate for us all to have an inherent understanding of these facial features.
For example, a child exposed to significant amounts of testosterone in the womb may be violent and shortsighted, but will likely also sport handsome features like a strong jaw and narrow eyes. While a child exposed to significant amounts of xenoestrogens may have wide, innocent eyes and a weak jaw, who will probably never step outside the status quo.
But even aside from such things, humans have developed specific prejudices towards certain physical types. Not just racially, but especially within their own races because exposure to certain hormones during development and birth leads to certain physical and facial features, reflecting certain mental traits that developed alongside. That is to say, if a man looks like a hard son of a bitch, he usually is. While a pussy may dress and act hard, but his face and body reveals otherwise.
Trust in your instincts, because they are usually right.
