Neanderthals don't sit like robots, they sit like people.
I sit this way because it seems natural. It is so easy to imagine people clustered around a campfire relaxing in these quixotic poses because they are ... dreamy, wry, impractical and unsophisticated in terms of their ability to calculate their body's appearance as a social stratagem. As one person noted, this takes the pressure off the soles of the feet making it a good way to sit despite not being "correct."
It is friendly and so very personable. This posture says I am more concerned with comfort than projecting discipline and regimentation.
I just see melonheads pulling Sapiens out of cloning vats and seating them at benches and all of them side-by-side with that exact same distance between their feet sitting parallel with their shoulders. They are more like automatons than natural, organic creatures. It is the Neanderthal who is warm, uncultured and lacking in a desire to do what most conforms in all things. Why are Neanderthals so slow to mature and always childlike even at 50? Homo Sapiens matures at half the rates of primates and maintains neoteny well into his 20's. The Neanderthals mature at half the rates of the humans for the exact same reason. Coupled with a superior intellect their childlike aspect keeps them much more creative, experimental and good at problem solving long after Homo Sapiens has completely shut down mentally. These qualities are the difference between life and death in an Ice Age in which most of the planet is covered with snow.
"Apparently sitting with your feet like this is really comfortable. I’ve tried it now, and it made me remember how many comfortable things we give up when we enter the world of adulthood and social referencing. The ability to be disconnected from social norms can cause problems - we hear lots about that - but it can also preserve behaviors that are timeless in their comfort and charm."Now for the big finish.
Every single study that has ever been done of workplace productivity has shown that people concerned with privacy, comfort and happy surroundings (the absolute opposite of cubicles, dress codes, authoritarian management and surveillance) are far, far more productive than their contemporaries who don't seem to mind. How productive? Ratios of 25-to-1 and 100-to-1 are common with such people. That's right. Objective metrics (seems certain to miss a lot that might also be pertinent) has revealed such people can do 25 times the amount of work in a day that ordinary people can. A shame the world isn't really like Saps imagines it to be at all. Of course, such people are the first to be terminated/expelled/forced out in political struggles for power every time. The research proves as much every single time they study the phenomenon.
