If I'm interpreting the question correctly, our IQ does in fact already determine who we are, whether we like it or not. IQ is not something like race where we have no choice over. We can improve our IQ if we choose to. Therefore someone's IQ, just like their kindness or personality, does indeed already determine and define who they are.
yes to some extent iq determines who we are. however some people with high iq's can still do stupid things that injure themselves, especially males. how technologically advanced a society is depends on the average iq of its citizens. Africans have iq's of 70 or below and they have no advanced technology. America has an average iq of 90 to 100 and they have some advanced technology. china has the most advanced technology and has the highest average iq because they study the most.
just because a test says yours smart or dumb doesn't make it so
No, I wouldn't want idiots to define people by their IQ.
Why? Just because you are smarter or maybe not as smart, doesn't mean you should let that quality define who you are as a person.
Some of the most honest and righteous people in the world are on the end of the IQ spectrum. These people should not be defined negatively because their genetics didn't win them a lucky brain.
