===Paranormal abilities===
Some individuals in the stories display limited paranormal or "psionic" abilities. [[Gil Hamilton]] can move objects with his mind using his phantom arm, which he gained after losing an arm in an asteroid mining accident. When he finally had the arm replaced from an organ bank on Earth, the ability persisted. "Plateau Eyes" (introduced in ''A Gift From Earth'') is an ability on the part of some to hide in plain sight, by causing others not to notice them. Population control is tight on Earth, but these abilities can gain the possessor a license to have more children. The Pierson's Puppeteers engineer a lottery for child licenses on Earth to increase the occurrence of "luck", which they think is a paranormal ability humans have that has enabled them to defeat races such as the Kzinti. In ''Ringworld'', the character Teela Brown is said to have this ability (although possibly not to the same extent as others who avoided being included in the expedition).
