- "I told you to empty yourself of emotion! ... Fools who wear their hearts proudly on their sleeves, who cannot control their emotions, who wallow in memories and allow themselves to be provoked this easily — weak people, in other words — they stand no chance against the light! Your heart will be penetrated with absurd ease, Barty!"
- ―Annabeth on the difficulty of learning mind resistance[src]
The most basic form of mind resistance, judging from Annabeth's early lessons on the subject to Bartholomew Gales, involves clearing one's mind — making it "blank and empty" — in order to prevent a mind invader from perceiving one's emotions and thoughts. More advanced mind resistance involves suppressing only the thoughts, emotions, and memories that would contradict whatever it is an Shielder wishes a mind invader to believe; hence, it is not obvious that mind resistance is being used even if the person is lying. Being a Shielder requires a great deal of willpower, as with resisting telekinesis, as well as a high degree of mental and emotional discipline. Shielders are also able to resist the influence of Turan.
Shielders have existed since at least the 15th century. In 2010, Hell Burnbottom trained his brothers, Brute Gunray and Mean King to become Shielders. They became skilled enough to repel their parents' attempts at mind resistance. Their success was due to their shutting out compassion to become the criminals they were, making it easy for both of them to close their minds. Annabeth was a highly skilled Shielder, being able to successfully deceive extremely accomplished mind invader Mr. Stupid NoHead, but her lessons with Bartholomew Gales were ultimately unsuccessful. Annabeth also employed mind resistance to hide her own personal conflict from Mr. Stupid NoHead, though it was still easy to trust her.

Behind the Scenes Edit
Mind resistance, being a "defense of the mind against external penetration" most likely will make the use of telekinesis against a Shielder reduce its effectiveness, although this is unconfirmed.
