Ziggy, the HR profession, I understand, is working to develop screening tools for sociopaths. By way of example, my son is in a police Force and the final interview in a nine month screening program was conducted by Two "nice little old ladies" who asked him a series of questions about situations that he had no trouble answering, but would be impossible for a sociopath to answer. I recognised it as a screen for sociopaths. I won't explain further because I don't want to give the game away.
The trouble is that we have at least Thirty years of sociopaths climbing the management ladder and some have climbed very high indeed - one made it to Prime Minister, for a little while.
