Lying has developed so heavily in humans that just lying at a young age is a typical sign of proper brain development. Then again, lying can take on a multitude of different fashions from white lies, malicious lies, fiction, etc. The idea to think against our situation is an asset that makes us human.
Our intelligence is very finely lain with our social ability so to speak. The ability to understand, grasp, and communicate complex ideas is what makes us so intelligent.
I'm...
Just gonna let that one go, actually, that's gonna open up a whole can of psychological science that I really can't be bothered to get into, though I will say that our intelligence and speaking capabilities are apparently different things entirely, someone can be functionally retarded (Verbatim: "I hate..., My mum works over at the, over on the ward and she said 'not another bank statement.' I said 'It's the second one in two days.' And she said 'Do you want me to go to the bank for you at lunchtime?' And I went 'No, I'll go this time and explain it myself'."
That was from Steven Pinker's book called the language Instinct, good read, though hard to slog through like most scientific books, the person speaking up there cannot read or write, doesn't even have a Bank Account, and even though she later speaks about her boyfriend sharing a joint account with her she doesn't have a boyfriend, another man was handicapped in speech, but all his other mental faculties when reviewed were actually in the high average range, again, verbatim: [And have you been going home on weekends?] "Why, yes... Thursday... er, er, er, no, er, Friday... Bar-ba-ra... Wife... and, oh, car... Drive... Purnpike... You know... Rest... And teevee."
His writing was just as bad, and while he could understand and answer a question like 'Does a stone float on water?' He couldn't with questions that required grammatical analysis like 'The Lion was killed by the Tiger: Which one is dead?')
Oh goddammit I wrote all this and I'm probably agreeing with you, too, I just misunderstood your sentence.
