I know it is, because I learned at a very early age what the world is like. When Venus and Mars are in conjunction in a chart, there is a sort of speed and magnetism in the individual. Both planets are general, rather than particular, and other people sense a combination of interest in the world and other people, together with an intention of interacting with them. There are at least two problems here. One's upbringing is unique, and also most people are largely, if not totally, unconscious of the internalised portion of their Superego.
People learn about how their ego planets function by dealing with reality.
Let us suppose three possible situations. The conjunction is well aspected. There will be an unconscious knack of getting things right, when dealing with the world, for the internal rule system is accurate and the emotional response pattern appropriate, even if the individual is unconscious of all of this. So, for example, someone with Mercury trine the Uranus-Neptune conjunction will find that they have innovative and imaginative ways of organising themselves and that they are in the right place at the right time. The conjunction is badly aspected.
