  If a body of evidence can only support one doxastic attitude between belief, disbelief, and suspension of judgment with respect to \(P\), and two people who share their evidence disagree about \(P\), then one of them must have an unjustified attitude. So, if the Uniqueness Thesis is true, there is a straightforward route to Defeat. However, if evidence is permissive, allowing for multiple distinct justified attitudes toward the same proposition, then discovering that someone has evaluated your shared evidence differently than you have need not give you any reason to think that you have made a mistake. If evidence is permissive, then you may both have justified responses to the shared evidence even though you disagree. So, another way to motivate the Steadfast View is to endorse evidential permissiveness. For reasons to reject or doubt the Uniqueness Thesis, see Ballantyne and Coffman 2011, Conee 2009, Frances 2014, Goldman 2010, Kelly 2010, Kopec 2015, Raleigh 2017, Rosen 2001, and Rosa 2012.
