My time is limited but I watched your video. The speaker was seriously lacking in evidence, data and conclusive findings. He mentioned simulations but I saw no data of any except a few stories of misinterpretation to support his claim.
The closest I could gather of his flimsy point was that our perception of reality is distorted to increase survival.
What's new? We perceive what we want to perceive. We perceive only what we need to perceive.
But perception is not only influenced by our senses, or interface, and our interpretation (constructs) but outside of our control by biology and biochemistry and physics. If I tamper with the electrical current on a computer can I get it to malfunction or slow. Absolutely. If I tamper with your hormones and nutrients can I alter your perception. Absolutely. Your conscious is not entirely within your control.
Gender is a biological system, first. The construct is formed by the meaning you apply to the system that is gender. And I can screw with your mental construct of gender by pumping you full of estrogen and observe you change from man to a man with female inclinations.
Biological and chemical systems are the closest I can say as existing components of reality, uninfluenced by our perception. On the other hand, our perception is greatly influenced by the balance of those systemic, scientific systems.
