Everyone runs three inner voices: Parent, Adult, Child

Berne's foundational model splits the personality into three ego states that take turns running the show. The Parent is the internalized voice of authority figures from childhood — rules, judgments, "shoulds." The Child is the seat of raw emotion, spontaneity, and old fears or desires laid down early in life. The Adult is the part that processes the present moment rationally, without the automatic overlay of either inherited rules or old feelings.

Crucially, these aren't ages — a fifty-year-old can speak entirely from their Child state, and a six-year-old can occasionally produce a startlingly Adult observation. Most people shift between all three within a single conversation, often without noticing.

Berne's real innovation is showing that communication problems usually come from a mismatch: one person addresses another's Adult, but the reply comes back from their Child or Parent, and the conversation quietly derails without either party understanding why.

Takeaway: before decoding any argument, ask which ego state each person was actually speaking from.
