  Suppose I believe \(B\), that global warming is happening. Suppose I also believe \(P\), that Taylor is my peer regarding \(B\) in this sense: I think we are equally likely to judge \(B\) correctly. I have this opinion of Taylor because I figure that she knows about as well as I do the basic facts about expert consensus, she understands and respects that consensus about as much as I do, and she based her opinion of \(B\) on those facts. (I know she has some opinion on \(B\) but I have yet to actually hear her voice it.) Thus, I think she is my likelihood peer on \(B\).
