There is no such thing as an underestimate of average intelligence.
Sentiment: NEGATIVE
It is impossible to underrate human intelligence - beginning with one's own.
You mustn't underestimate an audience's intelligence.
The average IQ in America is - and this can be proven mathematically - average.
It has yet to be proven that intelligence has any survival value.
I don't think there's anything unique about human intelligence.
Intelligence is not a science.
I believe I am more intelligent than the average person.
I don't believe that intelligence can be reduced to a number, frankly. But I can see how doing exactly that produces a useful sorting mechanism in our society in order to separate children into categories of promising and doomed. The tests seem arbitrary and without real scientific value and yet have lasting consequences.
Up to this day, there has been no proof of the existence of any intelligence other than the human.
It is not clear that intelligence has any long-term survival value.
