Some Anti-Stratfordians say William Shakespeare lacked the education, aristocratic sensibility, or familiarity with the royal court. They also say that these characteristics can be found in his works. Those Shakespeare scholars who have responded to such claims hold that biographical interpretations of literature are unreliable in attributing authorship, and that the convergence of documentary evidence used to support Shakespeare's authorship—title pages, testimony by other contemporary poets and historians, and official records—is the same used for all other authorial attributions of his era. No such direct evidence exists for any other candidate, and Shakespeare's authorship was not questioned during his lifetime or for centuries after his death.
