Intellect is the ability of the human mind to reach correct conclusions about what is true and what is false in reality; it is associated with capacities such as reasoning, conceiving, judging, and relating.
The conceptual model of mind is composed of the mental and emotional processes by which a person seeks, finds, and applies logical solutions to the problems of life.
[9] In 1955, the psychologist Joy Paul Guilford (1897–1987) proposed a Structural Intellect (SI) model in three dimensions: (i) Operations, (ii) Contents, and (iii) Products.
In psychological praxis, intellectualization is a defense mechanism that blocks feelings in order to prevent anxiety and stress from acting upon and interfering with the psyche of the person, which otherwise would interfere with their normal functioning in real life.
The purpose of intellectualization is to isolate the Id from the real world, and so make the conscious aspects of a person's life the only object of reflection and consideration.
[12] Socially, intellectualization uses technical jargon and complex scientific terminology instead of plain language; e.g. a physician uses the word carcinoma instead of cancer to lessen the negative impact of a diagnosis of terminal disease — by directing the patient's attention away from the bad news.
