We analyse the quality (informativeness and efficiency) of advice obtained from a committee of careerist experts where voting is secret but voting profiles are 'leaked' with an exogenously given probability. We show that fully informative voting is generically possible only when the common prior is not too informative, the committee uses the unanimity rule and faces the possibility of leakage. It is then shown that informativeness and efficiency are mutually exclusive properties of expert committees.

Keywords: Leakage, Career Concerns, Informative Voting, Welfare.
