We can never truly say for sure, but it’s the closest situation that can give a side by side comparison. Either testosterone allows better emotional inhibition, or estrogen reduces it. The main point is that men aren’t emotionless. Our emotions are just as strong as women’s, we are just better able to contain them (for better or worse).
Society then amplifies what is already there.
This sort of situation is how I knew my wife was/is a keeper. When I was pushed to the point where my negative emotions got too much, she was there for me. She didn’t shy away, but stepped in to help and support me.
In many of my previous relationships, showing negative emotions was lethal to their feelings. I could be happy, or stoic, but never upset or depressed.
On a side note, I had a chat with a trans friend once, regarding emotions. When they transitioned, the intensity of their emotions didn’t change much. However, their ability to contain them plummeted. Basically, men and women feel emotions similarly. Men are just a lot more able to bottle them up.
It’s interesting to look at what is actually required to be a technological species (assuming they develop it themselves).
To make technology, you need something to manipulate the world reliably. Hands are the most obvious method, but not the only ones. Octopus tenticles could also likely fill the roll.
Developments are useless, if they can’t be passed on to the next generation, or shared around. Technology requires building on the work of others.
There needs to be something to drive early brain development. With humans, it was likely sexual preferences. It could otherwise become a chicken and the egg type problem.
A specialist species will tend to lean into their strengths. There’s far less need for intelligence when you have big claws, or heavy armour already. This also applies to size. Too big, or too small tends to specialise in a why the precludes other developments.
There are several species on earth that hit some of these points, but not all. E.g. Dolphins hit all but the manipulator issue. Octopus are completely solitary. Many mammals hit all but brain development, and crabs overspecialise.
I could easily see a small tweak leading to a radically non human technological intelligence. That is also based only on what has already developed and stabilised in the earth’s biome. The cambrian explosion showed that far more body forms are at least viable.
It depends on your vehicle.
I personally drive a van, most of the time. Checking over my shoulder is a waste of time. What I do need is situational awareness. I’m aware of where my blind spots are, both absolute (e.g. directly behind my back bumper) and partial (e.g. the spot down my side).
I try and keep an awareness of everything entering and leaving my blind spots. I also do 2 checks of all spots that could have problems when manoeuvring. It’s alarming how often a small car or bike can slip through blind spots, when you’re doing your checks.
Basically, know your vehicle, and do what’s appropriate to keep everyone safe.
It was when she started on the hormones. Apparently, it wasn’t surprising to her friends going through the same process.
Unfortunately, I only know 1 trans person well enough to ask them about it. Also, considering it’s a binary (either men feel less, or are better at containing it), I would be surprised if it goes the opposite ways when transitioning.
It’s not a scientific study however, just an interesting and relevant observation.
