Eric Berne developed the notion of transactional analysis (TA ) and author of the book "The Games People Play".
Thomas A Harris then wrote the book "I'm OK - You're Ok" based on Berne's theory of TA.
Tony White expanded on this theory.
They produced the following concepts about people's life positions. As a basis for a person's way of relating to others and the world.:
"I'm OK, You're OK"
"I'm not OK, You're OK"
"I'm OK, You're not OK"
"I'm not OK, You're not OK"
"I'm not OK, But You're Worse"
"I'm not OK, You're Irrelevant"
"I'm a Bit More OK Than You Are"
"I'm OK, You're Irrelevant"
"I'm OK, You're OK, They're not OK"
