In this paper we examine the strategic implications of collective acquisition of information in a committee or in a legislature. We show that the prospect of acquiring information can harm a majority even if information is only available by the support of a majority. Moreover, the model provides two results about incentives to acquire information. First, for policies with high distributional uncertainties, we expect that less information is acquired collectively by a committee than for other policies. Second, for policies that show only size uncertainty, our model predicts intense efforts to acquire information collectively.
