You're OK refers to social issues contemporary at the time of writing, including the Cold War, Vietnam war and the contemporary controversial research of individuals' response to authority conducted by psychologist Stanley Milgram. Harris applies TA to these issues and concludes his book with the hope that nations will soon gain the maturity to engage in Adult to Adult dialogue, rather than conducting diplomacy in the collective archaic ego states of Parent or Child, which he sees as causing war and disharmony. Editions The book was published first during 1969 in the United States by Harper & Row, then republished as I'm OK- You're OK (). In the United Kingdom it was published first during 1970 by Jonathan Cape with the title The Book of Choice. It is still in print, published by Harpercollins. Criticism The work of Wilder Penfield concerning human memory, which appeared to Harris to give TA special credibility because it implied a direct association with neuroscience, has not proved readily repeatable. However, recent data (King-Casas, B., Sharp, C., Lomax-Bream, L., Lohrenz, T., Fonagy, P., and Montague, P. R. (2008). The rupture and repair of cooperation in borderline personality disorder. Science 321, 806–810. doi: 10.1126/science.1155236902) show the mechanism by which OK vs not OK judgements of value are made in the insula, moment to moment, so Harris' notion is supported. Harris's assertion that a child does not mature with the life position I'm OK - You're OK without therapy has been criticised as positioning TA as a quasi-religious soteriology. Harris' assertion that all children start out with an I'm not OK, You're OK life position was contested by his friend Eric Berne, the originator of TA, who believed that the natural state of a child was feeling I'm OK, You're OK. As several decades have elapsed since Harris published I'm OK, You're OK, some of the cultural references which were relevant at the time of the book's publication are now less accessible to contemporary readers not familiar with the period. Influence on popular culture The name of the book has since become used commonly, often as a dismissive categorization of all popular psychology philosophies as being overly accepting. The phrase I'm OK, You're OK is a common cliché in Anglophone culture, at least among an older generation more accustomed to hearing the phrase. Examples of the influence elsewhere are: Wendy Kaminer wrote a critique of the self-help
