“Great new ideas usually come from very small teams... don’t give up so easily." — John Kaster —
You need to keep in mind that your brain runs on instinct. Your brain, when making a code, wants to have an end result. Your instincts then tell you a code that would work and lead to your end result. The same thing works with finding food. You are hungry. Your instincts tell you to get food, and how to get it.

He is saying there is no such thing as instinct, because he thought up of that code.

If Itachi actually believes that humans don’t have instincts then I have no choice but to declare him legally retarded. No modern full grown human being that doesn’t have a learning disability or irregularity of some sort would actually think humans don’t have instincts.

I’m gonna have to disagree with you.
I’m pretty sure I know what you’re gonna say, and if so then I already see you’re point. I just don’t believe everything you do is running off what instincts tell you to do. Certain things such as finding food and other animalistic traits, sure. But every day life IMO isn’t governed by it.

I kinda do find it to run on istinct. What goes through our minds everyday is to survive. We do these actions because instinctually, we know it will have us survive.
Thinking is a real action, but it is caused by instinct though, so really, I just find thinking to be an instinct. Alot of people would disagree with me though.
