To understand Trump we need four knowledge ‘tools’

• nominative determinism,
• a holistic model of the human being:
• world-views / framing
• the mis-match between the writing and the write hand

Nominative determinism. We are our name eg Cartwright a cart builder, Joy a joyous person
In Trump’s case; no other card can beat a trump card.Trump said “We have all the cards” : he is ending Canada trade talk BBC News 29/06/2023

Holism. A holistic view of the human being regards the physical, intellectual, emotional and social entities as different facets and not separate  components. One implication is that if one facet is found to be out of kilter, on deeper probing, others will be found to be out of kilter too.

World-view / framing. Trump has himself stated that his world-view is that of dealing, with its roots in playing cards. It’s all about winning or loosing, with no middle ground.

Wright mis-match.i This mis-match s defined as not writing with the adept (or wright) hand. It is not about whether one is right or left handed. But it is not about only the hands: it is about the organization of the brain and the orientation of the body. One indisputable fact is that Trump writes (or rather signs his name, from the shoulder and staccato) with his right hand awkwardly.  Evidence for him being bio-logically left body oriented and therefore right cerebral hemisphere organized is visible for all who know what to look for: dancing, tree planting, signing his name from the shoulder and staccato fashion, and his head / heart felt hand talk. A major consequence of this condition is an ill-at-easeness, the  of whiccause h is projected on to everyone but himself!. Evidence for his left body orientation: the image on the cover of his TRUMP THE ART OF THE DEAL!!!
