I tend to agree. There are things that some groups find super easy, yet others struggle and I don't even talk about complex things like physics. For instance, I remember at Uni we had mechanical engineering classes where you have top, side, and front view and you need to draw the piece from a perspective. I could 'rotate' the object in my head like I was wearing a VR set,but some people absolutely struggled with even simplest objects. It'd be good to know why it's like this.
