, 19:57, 27 April 2010→Two Lobbies - Opposite Bias
With two lobbies where <math>\delta_1 < 0\,</math> and <math>\delta_2 > 0 \,</math> the policy maker can use the competition to become more informed, though not fully informed.
Crucially, define <math>\theta_2^* \equiv \theta_{max} - \delta_2 It is not possible to reveal the state of the world when \theta ,</math> \theta_2^*. See the paper for further information.
It is not possible to reveal the state of the world when <math>\theta > \theta_2^*\,</math> . See the paper for further information.
===Multi-dimensional Information===
When the groups differ in their relative bias on a single dimension there is full revelation. By choosing new dimensions through the multidimensional space it is possible (given the necessary dimensionality of the choices and alignment conditions) to establish full relevation through-out the space.
