+I would not be surprised to hear of an estimator responding this way
+even after Hubbard's calibration.
 Hubbard repeatedly conflates estimates of uncertain events
 with personal estimates of trivia questions with certain answers.
 These are functionally identical,
 but _feel_ very different.
-Hubbard could do better to correct this bias.
+Hubbard could do better to address this bias.
 
 If you don't know the answer offhand,
 imagine it has been lost to time.
