What are the obvious differences between men and women?

"What is a chair?"

Ask wiki:

A chair is a type of seat, typically designed for one person and consisting of one or more legs, a flat or slightly angled seat and a back-rest. It may be made of wood, metal, or synthetic materials, and may be padded or upholstered in various colors and fabrics.

See? Everything has a definition! That's one of the science attributes!

As a construct, we as a society have perceived individuals as men or women as someone who display a certain set of criteria based of visual and auditory indicators of masculine and feminine characteristics.

Absolutely. But we (as individuals) have to train our neural networks on live examples.

Since face feminization surgery exists, all these criteria ar known.

For example:

Possibly I'm overly generalizing, but I have it all covered under proportions.

The list itself is going to be different person to person but typical it is looks, mannerism and voice.

I have mannerism aeady. Adding voice! Thanks!

1. Body differences:
Aforementioned hip shape and proportions, width and size of most bones, body fat distribution, skin texture (crosslinked vs non cross linked collagen), Adam’s apple, muscle development (not guaranteed) average height, body hair, boobs, shoulder proportions (arguably part of bones), voice differences due to vocal cords and size of resonant bodies, internal organs. Chromosome differences, gait/movement (anatomical)

2. Facial differences:
Eyebrows, thickness of facial bones, muscle development of the jaw, fat deposits in the cheeks (other parts too), eyelashes, perceived intensity of stare, jaw width, facial hair, nose size, hair and hairline

3. Socialization and dress:
Clothes, shoes, jewelry, accents, makeup, plastic surgery, skin care, speech patterns (think the stereotypical gay voice), removal of body hair, behavioral choices and careers, preferences for partner, political affiliation, gait/movement (learned)

The listed characteristics together can generally be used to separate men from women but much like the ancient plucked chicken argument attempts to define exact terms and boundaries around complicated concepts to perfectly categorize usually ends up being a train wreck due to exceptions existing to every rule. I would still argue that just because nature can produce a biological travesty that is an abject failure at following the instructions with all the wonders of human consciousness and intellect once in a while doesn’t mean that gender doesn’t exist

Also since the list is about obviousness

I’d say physical outline, facial features and hair as well as voice (anatomical) hold first priority, it’s fairly intuitive but the brain has strong dedicated circuits for this kind of recognition that make it hard to cheat.

Second would probably be visible socialized characteristics and more subtle gait/ movement differences. You wouldn’t really think too long about the gender of someone who just wears somewhat different clothing or who just walks a bit funny, probably leads to other assumptions but gender rarely. Lastly would be organ differences as well as behavioral differences since one is hard to see and the other is fairly inaccurate and is more educated guesswork.

I think that what are the obvious differences depends on the observer. For each person it may be different, and each of the individual characteristics that have been mentioned here can be faked, like growing long hair, walking differences (a bit harder to learn), breasts (they have rather decent silicone ones), voice (takes a lot of practise) etc.

One day, quite a few years ago, I was in the evening in a parking garage in not the best part of town, and I entered my car. Suddenly a guy came to the car and opened the door where I was sitting. I looked at him with a very ugly look, like "whatdoyouwant" and he said sorry and closed the door and left quickly. What I could make of it was that I had at the time rather long hair, and from behind he mistook me for a woman, and in his mind an easy victim.

I was mistaken for a woman when I was busy painting window frames, while wearing mini shorts and a t-shirt. I think ponytail and tight mini-shorts could play the trick.
