We analyze situations in which an expert is biased toward some decision but cares also about his reputation in the market for experts. The information the expert reveals decreases as his bias moves toward stronger preference for the status quo. We show that it is optimal to publicly disclose both the expert's contribution and his identity. Surprisingly, revealing the intensity of the expert's bias doesn't always improve the information he reveals in equilibrium. The presence of a second expert raises the first expert's incentives to report truthfully when reports are public, but reduces them when they are secret. In particular, having an option to call another expert may be detrimental in terms of information production if reports are not public. Finally, sequential consultation of experts reduces the information obtained when reports are public, but raises it when they are secret.
