I'm not naturally a deep thinker - the most basic of philosophical truths had to be told to me via online fora, in order for me to even think along those lines. I sort of absorbed and internalized how to think deeply - I might do it now, but it's not natural. That's the key. I wasn't having existential crises at 5, I started having them at 19. Because of the internet. I mean, I'm happy for the enrichment, but if I were more intelligent I would have figured all this out for myself, been less keen to think my way out of it, and would have been bothered much more by it. I grew up religious and started having my own doubts around 12, rather than disbelieving from the start. I'm gullible as hell and have to be on the lookout for the veracity of things, because I know I'm susceptible to magical thinking, romanticized narratives, and stuff that sounds just plain cool - if I don't research it (or get bitchslapped by the implanted rational part of my brain), I will
get sucked in. A person with a higher IQ would never need to be so careful.
