Subjective experience

Fi · Introverted Feeling

You may notice when a majority opinion flattens an individual's experience.

Overuse

Interpersonal Challenges

  • Explain any discomfort as a value violation.
  • May confirm a position internally without giving the other person enough information to understand it.

When out of balance, you may repeatedly test whether you are true or not, turning complex problems into moral judgments for yourself or others.

Practice

Growth Suggestions

  1. Translate value judgments into specific behavioral requests.
  2. Distinguish between the feeling being true and the interpretation necessarily being correct.
  3. Look for actions that protect both self and practical responsibilities.
