Your Personality Holds the Key
While I understand the skepticism towards most personality assessments outside of the Big Five, I am an "assessment maxi."
The specified languaging and cross-population correlation is sufficient to be useful.
Even if the outcomes change depending on the time of day one takes it, perhaps there's an underlying truth because of the variability.
We have different selves.
But I also suspect that there are many things which maintain consistency, and only if we truly know ourselves and how we interact with people as a result of our personality can we find "personhood-market" fit.
This realization is ultimately a Truth that has leverage.
The anxiety and violence within relationships that then translates to companies (companies are an artificial environment for business relationships) can be assuaged with this greater self-understanding.
