IQ can certainly be changed. Yours changed when you grew up. Studies have shown that it changes significantly (15+ points) in teenage brains as well.>it's a test right, so what if you took it years later where you knew more shit
How much you know is not intelligence. IQ tests are not intended to be measures of knowledge.>>10481720
Subjective to an extent. You can build up a pretty clear picture of it if you understand what it is, though. There are many traits that are universally considered signs of intelligence, and intelligence shows itself very clearly, the majority of people can recognise it in some form.>>10483101
Stress and anxiety certainly does bring your intelligence down, especially over the long term. Anxiety essentially interrupts cognitive functions and prevents them from working smoothly, and your intelligence is just an emergent property of your various cognitive abilities working together in harmony to produce thoughts and actions that can be considered valuable/useful.>I can only imagine what would happen if you completely take away all emotions and feelings from a person.
Not as interesting as you think. Becoming a Vulcan doesn't necessarily make you any smarter, it usually makes you duller. We take for granted the unconscious motivations that drive our thinking, especially our system 1. The motivations that drive your brain to work for your benefit, to solve problems as you see them, to shape your environment a certain way, to choose what to focus on and what to react to and how to react to it, to put in the effort to adapt and change your thinking as necessary. When you get rid of the emotions, you get rid of the motivations as well.
