Gold Gloves are largely reputation based - and usually a player has to become good offensively to get on people's radars. It's silly of course.
Cy Young tends to be solid largely - there are some shaky years (Welch over Clemens in 1990) but largely the voters seem to do fine.
MVP you get a lot of doozies because of how open ended the criteria is and writers projecting the value of contention (which means it's a referendum on a player's teammates). In my lifetime as a fan, just looking at the AL there have been howlers. For a quick version, I used baseball reference, and said it was a good vote if the MVP was within 1.5 WAR of the lead. This means that a bad choice is one where there were obviously better candidates. I noted a couple of borderline years where voters chose the 2nd best player by WAR in a year where the leader was a pitcher who lapped the field.

2004: Vlad over Ichiro, Johan Santana, Schilling, ARod, Tejada
2006: Morneau over Santana, Sizemore, Vernon Wells, Chien Ming Wang, Carlos Guillen
2009: Mauer over Greinke (Greinke was really good for KC that year, but Mauer was excellent choice among "everybody else")
2012: Cabrera over Trout
What is encouraging though about all the awards is that as the writers have turned over, the voting has gotten better informed. There are notably "finer" choices in the 2000s.
