Episode notes
Predictions Function As Commands
- Predictions often act like commands rather than neutral descriptions of future facts.
- Carissa Véliz argues tech executives' forecasts function to persuade audiences to buy their vision, benefiting the predictor financially.
Self Fulfilling Prophecies Erase Counterfactuals
- Self-fulfilling prophecies can cause events they predict by changing behavior rather than merely describing outcomes.
- Véliz illustrates with a teacher telling a student they'll fail, which can make the failure happen and leaves no counterfactual data.
Theranos Example Of Prediction Without Evidence
- Elizabeth Holmes promised a one-drop blood test and used optimistic prophecy to attract investors and attention.
- Véliz notes the prediction influenced reality (investment, trials) but lacked scientific progress and ultimately crashed.
