This is an interactive personality test that will calculate an A/B personality type for you.
Type A and Type B personality theory was devised by doctors Meyer Friedman and Ray Rosenman in the 1950s. They claimed that a certain type of people, "Type A", were much more likely to get heart disease, because of their high stress lifestyle, than other people, "Type B".
A/B personality theory never became widely used in cardiology, the claim that A/B type predicts risk for heart disease is disputed, but the distinction between type A and type B has become a popular one in non academic terms.
This test was developed for this website using descriptions of the types from Friedman (1996) - it has no serious research as to its validity.
The test consists of ten pairs of sentences, for each pair, you much choose which one is closest to describing you. The test should take 2-3 minutes to complete.
