I seem to be intelligent, at least compared to the people I meet and deal with on a daily basis, though whether that's because I have raw computational power, or just clearer/more effective ways of thinking about things, I shall never know. It probably comes out as the same thing.
I exhibit what seems to be a voracious mental apatite; it manifests as an urge to learn about the sciences, an obsession with maths, a wide-spectrum reading list and an addiction to puzzles. Sometimes I find I can't find enough stuff to test myself against, but that may just be boredom.
[sup]And I can't stop writing for the RP forum here, but that is probably evidence against me...[/sup]
If you care for IQ scores, I came in at 149 when I got tested by an educational psychologist. That said, this was a few years ago, and since such scores are known to deteriorate with age, I may have gone down since then, and it only proves that past-me was good at IQ tests.
[sup]She also found that I'm reasonably far down the aspergers spectrum. Which probably explains why I'm so damn smug.[/sup]
Abstract thought: Abstract thought isn't hard, and I find it irritating when people don't understand things.
Understanding: My understanding is rapid and comprehensive. Granted, the complexity of what I learn is limited by school and what books I can acquire, but rarely do I find that anything requires more than a second read-through.
Communication: This varies. I am verbally dexterous, and have no problem communicating in normal contexts. When I get to intellectual communication, I have a bad habit of skipping out parts of my thoughts that seem obvious; this is limiting to all but a few people, most of whom know me very well
Reasoning: I find much logic and mathematical argument to be easy; though I have no tolerance for formal logic [http://en.wikipedia.org/wiki/Mathematical_logic] since I have yet learn it.
Learning: Capacity for learning is proportional to interest; if i find something stimulating, my rate of ingestion becomes almost aggressive. I adore adding to the areas of knowledge which I find worthy.
Retaining: My mind is like a sieve; anything judged unworthy or uninteresting is discarded in favour of raw processing power. That said, my short term memory is excellent.
Planning: I am capable of coming up with complex, convoluted plans, which often require altering at the last minute. This is fine, within the boundaries mentioned in Communication.
Problem solving: Give me a problem, and I will attack it relentlessly until I have a solution. This can be a weakness; I dislike having to leave a problem unfinished.
