Red hair occurs in about 4% of people in the United States, yet it is never treated as a sign of a psychological disorder. Which point does this make?
ABeing atypical is not enough to be disordered
BAny trait under five percent is disordered
CPhysical traits never signal any disorder
DCultural values alone decide every diagnosis
Answer & Solution
Correct answer: A. Being atypical is not enough to be disordered
1. Atypical means a characteristic deviates from the norm, and red hair at about 4% clearly does.
2. Red hair still carries no distress, no dysfunction and no impairment, so nobody calls it disordered.
3. Rarity by itself therefore fails as a criterion, which is why no cut-off percentage can define a disorder.
4. Cultural expectations are also insufficient on their own, and physical traits are not ruled out in principle.
