Priming has issues with repeatability in experiments.
To believe that "debunks" the entirety of heuristics and bias is completely absurd.
I think that book sucks personally. Just an incredibly dull book to read. The online social contagion that it is a work of fiction might actually be more interesting.
Maybe we could call it the "if a book bases it claims by citing a few papers, and those specific papers turn out to be bogus, then its claims are unsubstantiated" heuristic
You can't test yourself for ADHD by taking amphetamines because they have profound effects on everyone - there's a reason why stimulants are some of the most popular recreational drugs. They can make everyone feel smarter, more productive, like you're on top of the world, especially at recreational doses.
When it comes to therapeutic doses for treating ADHD, the effects of the medication should be very subtle, you shouldn't "feel it working" like you've just taken that pill from Limitless. It can produce some euphoria or other recreational effects initially but they're supposed to disappear within a couple of days or weeks, otherwise your dosage is considered to be too high.
You cannot test yourself for ADHD - you need to do the actual work that is required for a proper diagnose. And you cannot test yourself for anything at all by taking amphetamines. Seriously. You were using it recreationally. When you post stuff like this online, people that believe what you write could get hurt.
Humans are the only known organism to do System 2 (which doesn't mean we're the only ones that do it, just that we don't know if whales do it), but System 2 is what the author is talking about when they refer to Chains of Thought.
System 1 is what they're referring to when they talk about Messi reacting to an unusual situation on the field.
Related anecdote: I tested myself for ADHD by taking amphetamines. I normally think by intuitive leaps from point to point, without doing the intermediate steps consciously. I found that during this experience my System 2 thinking was fast enough to follow and I actually experienced proper chains of thought. Or I was whizzing my tits off and hallucinated the whole thing. Not sure yet. I should repeat the experiment.
