I think our geometric intuition could never be good for a high dimensional object. Consider a sphere in 3D. It's represented by the points which satisfy x^2 + y^2 + z^2 = 1. Because there are only three coordinates, knowing the value of one of them greatly reduces the possibilities for the other two. For example, if I know z is close to 1, then my point is close to the north pole (x and y are both close to zero).

However, if I have the n-sphere x_1^2 + x_2^2 + ... + x_n^2 = 1, knowing the value of x_1 gives me very little information about all the other coordinates. And humans' interaction with the geometry is reality is somewhat limited to manipulating one coordinate at a time, i.e., our intuition is for built on things like moving our body linearly through space, not dilating the volume or surface area of our bodies.
