The myth on "stupideness" of blondes vs brunettes has a simple explanation from the elementary body language observation. The color of eye matter, not intellect.

Intellect is not correlated with color of hairs. The

• Emotions can be read of from pupil dynamics
• Blonde’s pupil is more easy to detect
• Brunette’s pupil is harder to detect
That is all
• Oh, yes, one more: Gollum is the best actor from the Lord of the
Rings
