Chapter 1: What is the main topic discussed in this episode?
You're listening to TED Talks Daily, where we bring you new ideas to spark your curiosity every day. I'm your host, Elise Hugh. What do the story of Oedipus and your insurance premiums have in common? More than you'd think. They're both driven by self-fulfilling prophecies.
Even though we tend to associate prediction with knowledge, I'd like to invite you to consider the possibility that most of the predictions that you encounter in an everyday setting are closer to the realm of power than that of knowledge. Predictions are often power plays in disguise. They justify value-laden decisions under the pretense of facts.
That's philosopher, AI ethicist, and TED fellow Carissa Veliz. In her talk, she traces the hidden power of prediction from kings who banned or even killed prophets to AI algorithms quietly making decisions about your life right now.
Chapter 2: What do Oedipus and your insurance premiums have in common?
Better understanding prediction matters more than ever, because we're relying on forecasting more than ever with AI. And based on how we talk about prediction, we're being much too naive about it. But AI is science, you might think. It's cutting-edge technology. Well?
Depends on the kind of AI and how we use it. Her message? The next time someone tells you a specific outcome is inevitable. Remember, they aren't necessarily describing the future. They might be selling it instead. That's coming up right after a short break.

And now, our TED Talk of the day.
Let me tell you about the future. Predictions are the boxing ring where fights over the future take place. As the story goes, King Louis XI kept an astrologer in court. One day, the astrologer predicted that a lady of the court would die within a week. When she did, Louis was shaken.

Chapter 3: How are predictions often power plays in disguise?
Either the astrologer had murdered the woman to prove his accuracy, or he was so prescient that he could threaten Louis himself. The astrologer had to be murdered. The king ordered his servants that upon his signal, they were to throw the astrologer out the window to a certain death. You'd be surprised, by the way, by how many seers in history have met this fate.
So advice to astrologers, keep away from kings and heights. When the astrologer arrived to meet Louis, the king asked him one last question. Given your prophetic abilities, tell me, how long will you live? Not missing a beat, the astrologer replied, I will die three days before your majesty. And Louis never gave the signal. Did the astrologer find his answer in the stars? I don't think so.
I think he understood the power of prediction and used it to get himself life insurance. Smart astrologer. Even though we tend to associate prediction with knowledge, I'd like to invite you to consider the possibility that most of the predictions that you encounter in an everyday setting are closer to the realm of power than that of knowledge.
It might seem that the days in which we sought astrologers and soothsayers to tell us about the future are very distant. But often we use AI as the new Oracle of Delphi, and tech executives whisper in the ears of our leaders, much like court astrologers used to. Granted, the technology is different, but the political role is not. Predictions are often power plays in disguise.
They justify value-laden decisions under the pretense of facts. Better understanding prediction matters more than ever, because we're relying on forecasting more than ever with AI. And based on how we talk about prediction, we're being much too naive about it. But AI is science, you might think. It's cutting-edge technology, right? Well, it depends on the kind of AI and how we use it.

Chapter 4: Why is understanding prediction more important than ever?
AI can be a great technology to make predictions about molecules in the search for new antibiotics. But predictions about human beings are fundamentally different than those about things. Predictions about the weather don't influence the weather. Predictions about people influence people. Social predictions tend to act like magnets. They bend reality towards themselves.
They affect the reality they purport to predict. An algorithmic prediction about future disease can make someone's insurance premiums go up, leading to worse health outcomes from stress alone. Predictions sound like descriptions of the world, like facts, but they're not. Analyzed closely as assertions, they are what philosophers called speech acts.
That is, language that does something other than describe the world. When you tell a child to clean up their room, You're not describing the state of the room, you're issuing an order. Similarly, social predictions are veiled commands. They implicitly tell us how to act.
For example, when a tech executive says that in the future we will use AI for everything and everywhere, he's trying to get you to act in a way that will fulfill his vision of the future. You know, the one that happens to line his pockets.
And when you believe that prediction as if it were telling you something about the future, when you give in to the fear of missing out and you go and you buy the AI and you contribute to the self-fulfilling prophecy, what you are actually doing is obeying. Have you noticed how often people who make predictions about technology say that the future they are describing is inevitable?
That's a red flag. Those predictions are designed to act as conversation stoppers. They're telling you, don't question me, just accept what I'm saying as a fact. I'd like for this talk to be a conversation starter. I hope it will persuade you to ask more questions. Predictions invite manipulation. Their power to shape the future creates the temptation to tamper with it and benefit from it.
Take prediction markets. The argument for having them is that they can be a source of knowledge. In theory, markets don't lie. If people make bets and they stand to lose if they get it wrong, they'll try to get it right. And by having many people place bets, we can harness the wisdom of the crowds. But that assumes a very naive view of prediction as a quest for knowledge.
If you consider prediction as a quest for power, a very different picture emerges. If you have enough money, you can use it to influence public perception by heavily betting on something. Politicians have bet on themselves. In February this year, six anonymous accounts earned $1.2 million, betting for the attack on Iran. Some of those wallets were funded hours before.
Finally, predictions create and then cover up injustice. Algorithmic predictions are building this Kafkaesque world in which we can no longer contest decisions because they're not based on clearly defined criteria. If I reject your loan application because you don't fulfill a particular requirement, that's a verifiable fact. If I'm wrong, you can challenge me.

Chapter 5: What historical examples illustrate the dangers of predictions?
be like Joe Frazier. When Muhammad Ali predicted his own victory in the 1971 heavyweight championship, Frazier took it as a provocation and ended up defeating the previously undefeated Grace Ali in the fight of the century. So next time you hear a gloomy prediction about the social world, don't get discouraged. Find the Joe Frazier within you. rebel against tyrannical predictions.
Let's be brave enough to imagine and fight for a better world. Perhaps then, all of us can make the future bright after all. Thank you.
