Who writes

Miguel Díaz Zamacona is a psychologist specialising in negotiation, mediation and conflict resolution, and the author of «Arquitectura de la Manipulación» and «La Mente Revelada». He has led a European technology company for almost thirty years. He writes VIDHA alone, with no advertising and nothing to sell.

He came to psychology the long way round: decades leading technology companies, deciding with people and money at stake, watching people at the moments when judgement fails. In parallel he trained in neuroscience, behaviour, high-performance psychology and strategy programmes at Harvard, Stanford, MIT and Cambridge.

«La Mente Revelada» was born from an episode that changed everything: during his psychology studies he went through a long series of eye operations and a month completely blind. «Arquitectura de la Manipulación» is the result of years studying how emotional control is built — and how one gets out of it.

VIDHA gathers his psychoeducation guides: what is happening to a person, why, what they can do, and on what evidence. In Spanish, English and Chinese. The full biography, in his words.
