"Innies" refer to individuals who have a more introverted personality type. They often prefer solitary activities or small group interactions over large social gatherings. Innies tend to reflect deeply on their thoughts and feelings, which can lead to a rich inner life. They may find social situations draining and require time alone to recharge. This personality trait is part of the broader introversion and extraversion spectrum, as described by Carl Jung. While innies may be perceived as shy or reserved, they can be very observant and thoughtful, often excelling in tasks that require focus and concentration.
