Quiz — Test Your Understanding

Question 1 of 6
According to the book, why did the computer Deep Blue defeat chess champion Garry Kasparov?
  • A. Deep Blue possessed a deeper, creative understanding of chess strategy than Kasparov.
  • B. Deep Blue learned from Kasparov's previous matches and adapted its playstyle dynamically.
  • C. Deep Blue used massive raw processing power to calculate the probabilities of every possible move.
  • D. Deep Blue utilized a complex neural network to predict Kasparov's emotional state.
Question 2 of 6
What happens in the neocortex when you encounter a completely new and unfamiliar experience?
  • A. The information is rejected as an anomaly to protect the brain's existing memories.
  • B. The lower layers automatically associate the new information with the closest matching emotion.
  • C. The brain triggers a feedback loop to immediately reprogram the incoming sensory inputs.
  • D. The information travels up to the top layer, where it is stored as a new memory for future reference.
Question 3 of 6
How is the human brain able to predict future events, such as knowing a car engine will start when you turn the key?
  • A. By calculating the mathematical probability of all possible outcomes in a given scenario.
  • B. By recognizing patterns from past experiences and activating the sequence of previously associated reactions.
  • C. By relying on an innate, pre-programmed set of survival instincts stored in the primitive brain.
  • D. By utilizing the emotional centers of the brain to anticipate potential danger.
Question 4 of 6
What is identified as a major limitation of current artificial neural networks compared to the human brain?
  • A. They can only process information in one direction and lack feedback loops.
  • B. They require a central storage unit that severely slows down their processing speed.
  • C. They are currently too physically large to process basic computational tasks.
  • D. They generate unpredictable emotional responses that interfere with logical output.
Question 5 of 6
Which specific technology is mentioned as a potential solution for mimicking the massive interconnectivity of neurons required for intelligent machines?
  • A. Quantum microprocessors
  • B. Centralized cloud storage hubs
  • C. Single fiber optic cables
  • D. Advanced silicon memory chips
Question 6 of 6
Why does the book argue that intelligent machines will NOT pose a threat to humanity?
  • A. They will be programmed with strict, unbreakable ethical guidelines.
  • B. They will lack the physical mobility required to stage a revolt against humans.
  • C. Humans will always maintain control over their central power sources and hardware.
  • D. Their intelligence will be based on the neocortex, lacking the primitive brain regions that generate emotions like fear and hate.

On Intelligence — Full Chapter Overview

On Intelligence Summary & Overview

These blinks provide an overview of the human brain’s capacity for thinking and for comparing new experiences to old memories. They also explain why today’s machines still aren’t able to emulate this capability, but why we may soon be able to build ones that can.

Who Should Listen to On Intelligence?

  • Anyone interested in how the brain works or what makes us intelligent and conscious beings
  • Anyone who wants to know whether we’ll ever build machines that are truly intelligent
  • Anyone wondering whether such intelligent machines would be good or bad for humanity

About the Author: Jeff Hawkins and Sandra Blakeslee

Jeff Hawkins is the co-founder of the companies Palm and Handspring. After inventing the PalmPilot and the Treo smartphone, he began working for the Redwood Neuroscience Institute, a non-profit organization. It was there that he developed some of the theories presented in these blinks.

Sandra Blakeslee writes for the New York Times as a science correspondent. She is the co-author of several books such as Phantoms in the Brain.
