Pupil Size Is a Marker of Intelligence
We found that a larger baseline pupil size was correlated with greater fluid intelligence, attention control and, to a lesser degree, working memory capacity—indicating a fascinating relationship between the brain and eye. Interestingly, pupil size was negatively correlated with age: older participants tended to have smaller, more constricted, pupils. Once standardized for age, however, the relationship between pupil size and cognitive ability remained.

。
I have no right to call myself one who knows.
I was one who seeks, and I still am, but I no longer seek in the stars or in books;
I'm beginning to hear the teachings of my blood pulsing within me. My story isn't pleasant, it's not sweet and harmonious like the invented stories; it tastes of folly and bewilderment, of madness and dream, like the life of all people who no longer want to lie to themselves.Herman Hesse
