INTJs do not inherently dislike their past solely because of their Si (Introverted Sensing) function. The "demon" function is a term used in some personality typology systems to describe the weakest and least developed cognitive function in an individual's function stack. In the case of INTJs, their demon function is Si, which means it is the function they are least comfortable using and may struggle to incorporate into their daily lives.
Si is associated with remembering past experiences in vivid detail, being attuned to sensory data, and relying on past experiences to inform decision-making. For INTJs, who have dominant Ni (Introverted Intuition) and auxiliary Te (Extraverted Thinking), their focus is primarily on future possibilities, long-term planning, and objective analysis.
While the Si function is not central to an INTJ's cognitive preferences, it does not necessarily mean that INTJs inherently dislike their past. How an individual views their past is influenced by various factors, such as personal experiences, upbringing, and life events. Some INTJs may have positive memories from their past that they cherish, while others may have negative experiences that they would prefer to move past.
However, it is possible that the underdeveloped Si function in INTJs might contribute to a tendency to overlook or undervalue the importance of past experiences. They may focus more on the future and may be less nostalgic or sentimentally attached to their past than some other personality types.
It's important to remember that personality type is just one aspect of a person's individuality, and people's attitudes toward their past are shaped by a complex interplay of various factors, including personality, personal experiences, and personal growth. Not all INTJs will have the same perspective on their past, and individual differences should be taken into account when discussing this topic.
