From the Ted Talk by Ram Neta: How do you know whom to trust?
Unscramble the Blue Letters
You believe that the Sun is much lergar than the Earth, that the erath is a rlhuogy sriheapcl pnealt that rotates on its axis every 24 hrous and it revolves around the Sun once every 365 days. You believe that you were born on a particular date, that you were born to two human parents and that each of your human parents was born on an earlier date. You believe that other human bgeins have thoughts and flgienes like you do and that you are not surrounded by humanoid robots. You believe all of these things and many more, not on the basis of dciert observation, which can't, by itself, tell you very much about the relative size and motion of the Sun and the Earth, or about your own family history, or about what goes on in the minds of other humans. Instead, these beliefs are mostly based on what you've been told. Without spoken and wrteitn testimonies, human beings could not pass on knowledge from one person to another, let alone from one gonreaetin to another. We would know much, much less about the world around us. So learning about a topic by asking an expert on that topic, or appealing to authority, helps us gain knowledge, but, it doesn't always. Even the most highly restpceed authorities can turn out to be wrong. Occasionally this happens because a highly respected authority is dsisneoht and claims to know something that she or he really doesn't know. Sometimes it happens just because they make a mistake. They think they know when they don't know. For example, a number of respected economists did not expect the financial collapse of 2008. They turned out to be wrong. Maybe they were wrong because they were overlooking some important eeinvcde. Maybe they were wrong because they were misinterpreting some of the evidence they had ncoietd. Or maybe they were wnrog simply because they were reasoning clelrsseay from the ttaol body of their evidence. But whatever the reason, they turned out to be wrong and many people who trusted their authority eednd up losing lots of money, losing lots of other people's money, on account of that misplaced trust. So while appealing to authority can sometimes provide us with valuable knowledge, it also can sometimes be the cause of monumental errors. It's important to all of us to be able to distinguish those occasions on which we can safely and reasonably trust authority from those occasions on which we can't. But how do we do that? In order to do that, nothing is more useful than an authority's track rrceod on a particular topic. If someone turns out to perform well in a given situation much of the time, then it's likely that he or she will continue to porrfem well in that same situation, at least in the near term. And this generalization hlods true of the testimony of authorities as much as of anything else. If someone can consistently pick winners in both politics and baseball, then we should probably trust him or her to keep on picking winners in both politics or baseball, though maybe not in other things where his or her track record may be less stellar. If other fercoresats have a poorer track record on those same two topics, then we shouldn't tusrt them as much. So whenever you're considering whether to trust the testimony of some ariouthty, the first question to ask yourself is, "What's their track record on this topic?" And notice that you can apply the very same lesson to yourself. Your instincts tell you that you've just met Mr. Right, but what sort of track record do your instincts have on topics like this one? Have your instincts porevn themselves to be worthy of your trust? Just as we judge other people's testimony by their track record, so, too, we can judge our own intcnists by their track record. And this brings us one step cloesr to an objective view of ourselves and our relation to the world around us.

Original Text
You believe that the Sun is much larger than the Earth, that the Earth is a roughly spherical planet that rotates on its axis every 24 hours and it revolves around the Sun once every 365 days. You believe that you were born on a particular date, that you were born to two human parents and that each of your human parents was born on an earlier date. You believe that other human beings have thoughts and feelings like you do and that you are not surrounded by humanoid robots. You believe all of these things and many more, not on the basis of direct observation, which can't, by itself, tell you very much about the relative size and motion of the Sun and the Earth, or about your own family history, or about what goes on in the minds of other humans. Instead, these beliefs are mostly based on what you've been told. Without spoken and written testimonies, human beings could not pass on knowledge from one person to another, let alone from one generation to another. We would know much, much less about the world around us. So learning about a topic by asking an expert on that topic, or appealing to authority, helps us gain knowledge, but, it doesn't always. Even the most highly respected authorities can turn out to be wrong. Occasionally this happens because a highly respected authority is dishonest and claims to know something that she or he really doesn't know. Sometimes it happens just because they make a mistake. They think they know when they don't know. For example, a number of respected economists did not expect the financial collapse of 2008. They turned out to be wrong. Maybe they were wrong because they were overlooking some important evidence. Maybe they were wrong because they were misinterpreting some of the evidence they had noticed. Or maybe they were wrong simply because they were reasoning carelessly from the total body of their evidence. But whatever the reason, they turned out to be wrong and many people who trusted their authority ended up losing lots of money, losing lots of other people's money, on account of that misplaced trust. So while appealing to authority can sometimes provide us with valuable knowledge, it also can sometimes be the cause of monumental errors. It's important to all of us to be able to distinguish those occasions on which we can safely and reasonably trust authority from those occasions on which we can't. But how do we do that? In order to do that, nothing is more useful than an authority's track record on a particular topic. If someone turns out to perform well in a given situation much of the time, then it's likely that he or she will continue to perform well in that same situation, at least in the near term. And this generalization holds true of the testimony of authorities as much as of anything else. If someone can consistently pick winners in both politics and baseball, then we should probably trust him or her to keep on picking winners in both politics or baseball, though maybe not in other things where his or her track record may be less stellar. If other forecasters have a poorer track record on those same two topics, then we shouldn't trust them as much. So whenever you're considering whether to trust the testimony of some authority, the first question to ask yourself is, "What's their track record on this topic?" And notice that you can apply the very same lesson to yourself. Your instincts tell you that you've just met Mr. Right, but what sort of track record do your instincts have on topics like this one? Have your instincts proven themselves to be worthy of your trust? Just as we judge other people's testimony by their track record, so, too, we can judge our own instincts by their track record. And this brings us one step closer to an objective view of ourselves and our relation to the world around us.
