What Is Introverted Feeling? (Fi) | Cognitive Functions | CS Joseph

Summary

The speaker explains introverted feeling (Fi) through his cognitive-functions framework. Although the subtitles briefly say “introverted thinking” at the start, the rest of the video is about Fi.

Fi and Te

• Fi as personal moral judgment: The speaker describes Fi as judging whether something feels good or bad according to personal values. He contrasts it with extraverted thinking (Te), which he characterizes as relying more on external evidence, standards, or collective judgments about what is true or false.
• The Fi–Te axis: In his model, Fi and Te are opposing functions on the same axis. If one is higher in a person’s function stack, the other is lower. He lists ESTJ, ENTJ, ESFP, ENFP, ISTJ, INTJ, ISFP, and INFP as Fi users, meaning Fi appears among their top four functions.
• Function strength and awareness: He says people with stronger Fi reach personal value judgments quickly, though they may keep those judgments private to avoid conflict or discomfort. People with weaker Fi, in his account, may prioritize rational or practical decisions more often.

Examples and applications

• INFPs: The speaker portrays INFPs as attentive to their comfort and experience, suggesting that discomfort can prompt them to act. He also says they may care about how others view them.
• External information and qualifications: He claims that people on the Fi–Te axis can have emotional or value-based reactions to information such as news, statistics, and expert advice. He argues that some may feel safer relying on a qualified authority, even when that authority is mistaken.
• Drawing on others’ values: Using himself as an ENTP example, the speaker describes Fi as a “trickster” function for his type. He says he may ask Fi users how they feel about an issue and remember their responses to guide later interactions. He also suggests that people with other functions may learn or adopt values through interaction with Fi users.
• Social interaction: The speaker characterizes social behavior as a kind of “manipulation,” using the term neutrally to mean influencing or adjusting to other people’s responses.
• Status and recognition: He associates Fi users with wanting to feel valued and regarded highly, giving fame, attention, and status as examples. These are presented as broad, type-based tendencies.
• ENFPs and perception: He attributes the maxim “In the absence of communication or explanation, perception becomes reality” to ENFPs. He claims that, in some cases, what others believe can matter more than what is objectively true, and that a person may come to believe a story others accept.

These descriptions are the speaker’s claims within his typology model; the video does not provide sources or evidence establishing them as universal traits.
