Reifying led to the Shoah. For when we want to murdrer in large numbers, it is necessary first to reify the victims, so we won't feel guilt.
And we reify the victims by casting them as somatic types, that is, bodily types. This is called racism and is no longer socially acceptable, so the urge to reify our victims has moved from somatic types to psychological types.
So psychological typing is under the dark star of racism and the Shoah.
