Certain types of people seem to have a propensity to have accidents more often than others. Being labelled 'accident prone' could significantly limit employment possibilities, make one socially unacceptable, and result in a degrading self-image.
A recent major study on road accidents has shown that it is possible to lower the accident rate in a transport company by using psychological tests (which have been subjected to repeated cross validation) to screen out the bad accident risk people on the basis of their intelligence, psychomotor functions, personality, social attitudes and interpersonal relationships.
