First, there were two independent clinical psychologists who were present or on call 24 hours a day. They had the power to intervene and to remove anyone from the study if they thought they were in distress.

Third, the study was constantly monitored by members of a five-person independent ethics panel. This was chaired by a Member of Parliament and also included members of the Holocaust Educational Trust, the Howard League for Penal Reform, the BBC’s Independent Editorial Policy Unit and a senior academic psychologist. This committee had the power to change the way the study as a whole was run and to terminate it if they had ethical concerns.
