You receive a pink packet from Miss Lead, a notoriously deceptive truth-teller. You know that if you open the packet and do not find blank pages, then you will justifiably change your mind about the evidence being misleading. Indeed, you will infer that your previous fears about misleading evidence were themselves founded on misleading evidence. Should you open the pink packet? No, answers an advocate of self-censorship. Yes, answers an advocate of the principle that you should base conclusions on all (...) the available evidence. Your final deliberations will be guided by Gilbert Harman’s Thought. Ultimately, the case against opening the packet prevails. (shrink)
