Type A and B personalities | Life and style | The Guardian

How we change what others think, feel, believe and do. A simple division of preference or personality type is into Type A and Type B, which is based broadly on anxiety and stress levels. This typing was first described in relation heart disease in the s by cardiologists Meyer Friedman and R. It subsequently appeared in the Jenkins Activity Survey, which was originated to detect behaviors which lead to heart attacks Jenkins, Ayzanski, Rosenman, Redford Williams, a cardiologist at Duke University, later showed that the main hazard in this is when the Type A person has a tendency to anger and hostility. A subsequent study has challenged even this, throwing the whole validity of this typing as a predictor of heart attacks into doubt. Nevertheless, it is a simple typing difference and perhaps aligns with the Big Five factor of 'neuroticism', or tendency to anxiety.
