Oliver James,a British clinical psychologist, broadcaster, and bestselling author ('Affluenza', 'Britain on the Couch', 'They Fxxx You Up') says of this book: "A highly original and stimulating critique of the modern 'marriage crisis', supported by important yet sometimes uncomfortable truths." For many years, across the developed world, over 50% of new marriages have ended in divorce, or are predicted to do so in the fullness of time. And perhaps half the marriages that do not end in divorce are thought to be broadly unhappy. The explanations for the modern 'marriage crisis' usually include a widespread loss of 'traditional values'. However, contrary to popular belief, the evidence is that marriages were no happier in former times than today. The prime drivers of a low divorce rate in former times were difficulty in obtaining divorce, and the economic dependency of women on men. In his fourth book 'THE MARRIAGE DELUSION - the fraud of the rings?' British writer Mike Buchanan argues that most people in the modern era are unsuited to marriage. He argues that a number of groups have an enhanced risk of being unhappy in their marriages, these groups include introverts (54% of men, 47% of women). The book covers this personality type at length and covers other issues contributing to marital unhappiness including the different natures of men and women, individualism, declining love and lust, sex, personal aptitude for marriage, mutual compatibility, the link between extraversion and adultery, religious conviction differences, the genetic link to propensity to divorce, and depression. The book concludes with a number of realistic recommendations to raise the proportion of new marriages which are happy over the long term, thereby bringing down the divorce rate.
