Harry Potter: 10 Smartest Hermione Granger Moments

10. When She Told Harry Not To Go To The Ministry Of Magic – The Order Of The Phoenix

Going to the Ministry of Magic to rescue Sirius was one of the stupidest things Harry ever did. Despite the fact Snape had been teaching him Occlumency (the magical defence of the mind against external penetration), Harry believed the vision of Sirius being tortured to be real.

Hermione, on the other hand, immediatley suspected the vision to be false. After hearing Harry’s recollection, she pointed out how Voldemort may have deliberately planted said vision in Harry’s head in order to lure him to the Department of Mysteries.

Of course, Hermione turned out to be right. Had Harry bothered to consider his friend’s advice, he would have saved everyone from a lot of pain and misery. Indeed, Sirius would not have been killed if Harry had just listened to Hermione’s logical argument.
