What would it look like if someone was truly curious — if they actually wanted true beliefs? Not someone who wanted to feel like they sought the truth, or to feel their beliefs were justified. Not someone who wanted to signal a desire for true beliefs. No: someone who really wanted true beliefs. What would that look like?
A truly curious person would seek to understand the world as broadly and deeply as possible. They would study the humanities but especially math and the sciences. They would study logic, probability theory, argument, scientific method, and other core tools of truth-seeking. They would inquire into epistemology, the study of knowing. They would study artificial intelligence to learn the algorithms, the math, the laws of how an ideal agent would acquire true beliefs. They would study modern psychology and neuroscience to learn how their brain acquires beliefs, and how those processes depart from ideal truth-seeking processes. And they would study how to minimize their thinking errors.
They would practice truth-seeking skills as a musician practices playing her instrument. They would practice "debiasing" techniques for reducing common thinking errors. They would seek out contexts known to make truth-seeking more successful. They would ask others to help them on their journey. They would ask to be held accountable.
They would cultivate that burning itch to know. They would admit their ignorance but seek to destroy it.
They would be precise, not vague. They would be clear, not obscurantist.
They would not flinch away from experiences that might destroy their beliefs. They would train their emotions to fit the facts.
They would update their beliefs quickly. They would resist the human impulse to rationalize.
But even all this could merely be a signaling game to increase their status in a group that rewards the appearance of curiosity. Thus, the final test for genuine curiosity is behavioral change. You would find a genuinely curious person studying and learning. You would find them practicing the skills of truth-seeking. You wouldn't merely find them saying, "Okay, I'm updating my belief about that" — you would also find them making decisions consistent with their new belief and inconsistent with their former belief.
Every week I talk to people who say they are trying to figure out the truth about something. When I ask them a few questions about it, I often learn that they know almost nothing of logic, probability theory, argument, scientific method, epistemology, artificial intelligence, human cognitive science, or debiasing techniques. They do not regularly practice the skills of truth-seeking. They don't seem to say "oops" very often, and they change their behavior even less often. I conclude that they probably want to feel they are truth-seeking, or they want to signal a desire for truth-seeking, or they might even self-deceivingly "believe" that they place a high value on knowing the truth. But their actions show that they aren't trying very hard to have true beliefs.
Dare I say it? Few people look like they really want true beliefs.
I think you are confusing between wanting to know, and being good at it.
Imagine someone in the stone age, would you say none was genuinely curious because they didn't know about all those fields which weren't invented yet ?
Then, what about someone living in our world, but not knowing about Bayesian reasoning, AI, ... ? How can he know that those fields are fundamental to learn, to satisfy their curiosity on another field, before at least learning the basis of them ? When you don't know about Bayes' theorem, but you are curious (you really want to know the truth) about, say, ancient Rome history or about if there ever was life on Mars, what would drive you to learn probability theory ? How can you know you must learn it to learn other thing, when you don't know much about that other thing ?
Sure, if you are curious, you'll want to learn in all fields. But since we have a limited amount of time, you can't except someone to learn Bayesian reasoning, even if he's really curious, unless there is some kind of trigger that makes him realize how useful it would be to be efficient in being curious.
Genuinely wanting something and being good at doing it are not directly linked. You can't say someone isn't really wanting something just because he pursues it in an efficient way.
The stone age analogy doesn't quite fly. There's a difference between the state where I want X and someone else is offering X, and the state where nobody is offering X.
But you're right, of course, that even in the first case I have to know I want X.
That said, I don't have to know the name of the field.
For example, if I'm genuinely interested in what actually happened in ancient Rome (which is of course only one possible meaning of the phrase "ancient Rome history"), I will sooner or later discover that there are disagreements among experts about... (read more)
